AUGUST, ZOE VOL, V. APRIL, 1904. No. 10 A COLLECTION OF MEXICAN PLANTS. T. S. BRANDEGEE. Dr. C. A. Purpus, whois gathering cacti and orchids in Mexico, has made a most interesting collection during the past year, mainly from Ixtaccihuatl, a very high mountain not far distant from the City of Mexico, A comparison, in Biologia Centrali-Americana, of the mountain floras of Mexico makes no mention of that of Ixtaccihuatl, and it seems as if this collection might be the first one from that locality, Most of the plants collected are known from other parts of Mexico, and many of them have been previously ob- tained by Mr. C, G. Pringle on Nevada de Toluca, but a number of undescribed forms were found. ‘The plants from the high alpine region are especially interesting and a great number of them belong to genera growing upon the mountains of the “United States of the North.” MMontia fontana and Sagina Linnei seem to be identical with the northern plants. Ranunculus is repre- . sented by R&R. sibbaldioides and Donnianus—there are several species of Cerastium that seem to have been very abundant. Po- tentilla is represented by species rarely collected: P. ranuncul- oides, candicans, Richardit and comarotdes. Arenaria, Draba, Viola are well represented, and many other common northern genera were collected. Many thanks are due Dr. J. M. Greenmann for determinations of doubtful species. Thelypodium Mexicanum. Perennial, glabrous and glaucous, the leafy stems ascending 4-5 dm. high; larger leaves 10-12 cm. long, 2-3 cm, wide, spatulate, entire, acuminate, thin in texture, APRIL 18, 1904 180 A Collection of Mexican Plants. [ZOE broadly auriculate-clasping, upper leaves similar and smaller; in- florescence in a terminal spike and on short branches from the axils of the upper leaves; flowers light purple, petals linear, nar- rowed at the base, 3 mm. long; immature siliques 1 cm. long ona longer pedicel. ; Collected on Ixtaccihuatl, 1903. Thelypodium australe. An erect perennial, stems hirsute, especially below; leaves glabrous 2-4 cm. long, somewhat spatu- late, obtuse, entire, 5-7 mm. wide, narrowed to near the base then broadly auriculate; petals rose-purple, 3 mm. long: stigma slightly 2-lobed; immature siliques ascending, 2m. long on a shorter pedicel, forming a loose spike more than 2 dm. long. The specimens are young and do not have mature fruit. Col- lected on Ixtaccihuatl, 1903, at 9-10,000 ft. elevation, growing in open woods. No. 304. Dalea Lemmoni Parry, was collected at Ixmiquilpan, Hidalgo, July, 1903, No. 405. The type of the species was found by Lem- mon near Ft. Bowie, South Arizona, and a variety, daxa Wat- son, has been distributed with Pringle’s sets, No. 1758, from Za- catecas, but this variety seems like a distinct species. Dr. Pur- pus’ plant extends the range of D. Lemmonii much southward. Machaonia fasciculata Gray, was collected on the Sierra de la Mesa, near Ixmiquilpan. The specimens agree with Dr. Gray’s short description. The upper leaves are simply, and the lower fasciculately ternate. No. 446. Spermacoce ambigua. Glabrous' or hirtello-puberulent; stems 4-winged; stipular bristles few, longer than the sheath; leaves opposite, the lower ones apparently fascicled on account of the development of young shoots in the axils the larger ones lin- ear-lanceolate, attenuate into a petiole 2-3 cm. long, 5 min. wide; inflorescence axillary or in terminal spikes of small I-5 flowered cymes, the uppermost minutely bracted; internodes 1-2 em. long; peduncles and pedicels 1-2 mm. long; flowers tetra- merous; Corolla 2 mm. long, short funnel-form, lobes short, lin- ear-lanceolate; style -shortly branched; fruit turbinate, 1% mm. long; short calyx lobes persistent. VoL. 5] A Collection of Mexican Plants. 181 This plant is a doubtful Spermacoce. Its general aspect is that of a Linum. Only tops were collected and they seem to have belonged to a fruticulose plant, but it may have been an annual. The fruit is not quite mature, so that the appearance of the perfectly ripe seed is unknown, It separates into two un- equal one-seeded carpels that are entirely covered on the inner faces by the very thin dissepiments. The ovary is affixed at its middle to the septum and the radicle is inferior. No. 417. Cordoba, Vera Cruz. Gentiana perpusilla. Annual, stems several, one-flowered; basal leaves crowded, margins light-colored, 1 cm. long, ovate- spatulate, acuminate, connate-sheathing; stems slightly exceeded by the corolla that is green outside and light blue within; its lobes are short, the plaits broad and acuminate; capsule clavate- obovate at length exserted on a long stipe beyond the corolla. This minute species is very near G. humilis. It was collected in wet meadows above the timber line of Ixtaccihuatl. Gilia Purpusi. Annual, stem simple, erect, 1-2 dm. high, puberulent; leaves 3-4 cm. long, pinnate into 8-12 ovate, acute, sharp-incised leaflets that are cuneate at base into a short petiolule, gradually decreasing in size from the terminal one, upper leaves with few linear-lanceolate leaflets and the uppermost becoming the bracts of the few, loosely flowered panicle; corolla rotate, 15 mim. in diameter, deeply 5-cleft, light blue, lobes ovate; calyx 5- parted into linear, acute, white-margined lobes, longer than the capsule; seeds numerous, mucilaginous when wetted. This species is nearest G. zzcisa, from which it differs mainly in having numerous pinnate leaves instead of a few basal lyrately- pinnatifid ones. Collected at Viesca, Coahuila. No. 132. Castilleia Purpusi. Perennial, frutescent, hirsute; stems 1 dm. high, usually simple from long subterranean root branches; lower leaves linear-lanceolate, obtuse or acute, slightly attenuate at base, 114-2 cm. long, 3-4 mm. wide; upper leaves and bracts trifid, the central lobe much the longest; calyx deeply cleft in front, slightly so behind, the lobes entire or emarginate; corolla 3% cm. long, when fully grown exserted beyond the calyx lobes one-quarter its length: galea tomentose, green upon the 182 A Collection of Mexican Plants.

Col- lected on rocky slopes above the timber line of Ixtaccihuatl. No. 320. Krynitzkia Mexicana. Annual, 1 dm. or more high, rough- hispid, stems slender, branched; leaves oblanceolate, 1 cm. long; flowers in the axils of the leaves and bracts: corolla equalling the ovate-lanceolate, yellowish-hispid calyx lobes, 3 mm. long, crests inconspicuous: nutlets 114 mm. long, ovate-triangular, the angles rounded except near the base, strongly muricate-granulose on the rounded back and plane faces, the ventral angle beveled from the apex % the length of the nutlet to the deeply exca- vated deltoid scar; gynobase subulate—pyramidal. This plant is to be compared with K. pusilla Gray, a species with the flowers in small spikes that have a naked appearance as the mature fruit and calyx gradually falls away from the base upward. . Mexicana is upright, more leafy, the flowers not in spikes and bears very different, larger nutlets. Collected at Viesca, Coahuila, 1903, No. 126. Mr. Pringle’s No. 8301, also from Coahuila, is a larger form of the same species with more mature and rounder nutlets. NEW SPECIES OF MEXICAN PLANTS. BY J. M. GREENMAN. Cerastium lithophilum.

PALMS OF BAJA CALIFORNIA. BY T. S. BRANDEGEE. Washingtonia filifera, W. Sonora, Erythea armata and £.. edulis are grown in the gardens about San Diego, and a few young plants of EArythea Brandegei are established. The seeds of £. Brandegez have been extensively planted in Southern California recently, and it seems as if this palm should grow well in its new habitat, for it will not experience as much frost and ice as it does on its native mountains. Wendland based the genus Washingtonia upon a palm pre- viously known as Brahea filifera. W.vrobusta was later added to the genus, but is by many considered to be doubtfully distinct, and there seems to be a good deal of uncertainty concerning both these species. In Botanische Zeitung, 37, 1878, Wendland describes the genus Washingtonia and writes that credit is due to Herr J. Linden of Ghent for the first importation, perhaps in the year 1869—at the time of this description seed collected a few years after 1870 in Cantillas Cafion had been distributed. One of the earliest notices of the palms now known as Washingtonia is in Botanische Zeitung, 34, where Pritchardia filamentosa is men- tioned as a garden name for plants raised in Europe, said to have been collected about Arizona and the Colorado River. The locality from which the seed came that Wendland examined later is not stated.. Under the rule, “once a synonym always a synonym,’ the name Washingtonia has been changed to Neo- washingtonia, but, in common usage, the new name is disregarded. 188 Palms of Baja Caltfornia. [ZOE In Pflanzenfamilien the genus is considered by Drude a sub- genus of Pritchardia. Much of the W. filifera now cultivated in California probably came from seed collected along the western edge of the Colorado Desert and Cantillas Cafion, a locality in Baja California, just below the boundary line near Campo. This palm is a native of the dry climate of the interior, generally growing on the eastern slope uf the mountains, where in the bottom of the cafions their roots will find plenty of water. I do not know a locality where they are found in a cafion running toward the western slope, but they may grow in such situations in Central Lower California, where so many plants of the Colorado Desert find their way to near the Pacific Coast. Washingtonia Sonore was described from specimens collected about Guaymas by Dr. Palmer, and it is not improbable that the species may extend northward along the Gulf of California to the region about the Rio Colorado, from which the first plants of W. filifera came. This palm grows also at Mazatlan and along the coast of the Cape Region of Lower California. On account of its love for the ocean breezes, it is a more suitable palm for the upper California coast than W. Jilifera from higher altitudes and a desert climate. At San José del Cabo the residents recognize two forms of W. Sonor@, which they name ‘‘Palma blanca” and “Palma rubra.” A way of distinguishing with certainty these two varieties is by cutting into the trunk and the color of the wood, white or reddish, is then evident. There seems tu be no other definite character by which the two varieties can be dis- tinguished. Erytheas are palms of much slower growth than the Washing- tonias. £. armata, or the blue palm, is abundant in Northern Lower California, growing in cafions or along the sandy bottom of dry streams after they leave the mountains, on both eastern and western slopes. £. edulis, the Guadalupe palm, is endemic upon Guadalupe Island. On the eastern slope of the island it is confined to the cations, but on the western slope it often covers large areas. VOL. 5] Notes on Cactee. 189 E. Brandegei,* a description of which recently appeared in Gartenflora and is here reprinted for the benefit of those who may not have access to that publication, grows abundantly in the mountains of the Cape Region of Lower California, in the cafions or often covering mountain slopes on northern exposures. Gen- erally, the dead leaves fall away, leaving a hard, smooth trunk less than two feet in diameter, even though it may reach an altitude of 125 feet. When it reaches a great height, the trunks lose the stiffness of the other species of the genus and wave with the wind. It is known tothe people of the Cape Region as ‘‘I,a Palmia,’’ and a form of it not well distinguished they name “Palma negra.’”’ A few trees in cultivation about San José del Cabo are called Palma de Tlaco. The young buds, two feet long, are cut from the top of the tree and eaten by the people of the vicinity—they are soft and taste very much like a raw turnip. The young shoots of E. edulis also are eaten by the Mexicans. NOTES ON CACTEA. KATHARINE BRANDEGEE. The first ‘‘Nachtrage’’ of Dr. Karl Schumann’s ‘“‘Monographia Cactacearum’’ has appearod. It is a pamphlet of viii-171 pages, and covers the period 1898-1902. Perhaps the most noticeable thing in the work is the absence of the ‘‘Cat.’’ citations so numerous in the previous publication, but the many named ‘‘Reiches,’’ bringing together all sorts of heterogeneous elements, are still in evidence, *Erythea Brandegeei, C.

[ZOE The sequence of the subfamilies is not changed, but is suggest- edin the preliminary pages. In theearlier workit ran: Subfam. i. Cereoideze; ii. Opuntioidee iii. Peireskioideze. In the later this order is reversed, the seed coats are not mentioned, and the classification rests principally upon the presence or absence of barbed setze (glochidia). It is perilous in the present state of our knowledge to generalize upon the surface structure of seeds as is evidenced by his statement that the seeds of the Cereoidez are “always shining, brittle and black.’’ Certainly they are not always shining, and they are commonly red or yellowish-brown in two sections of Mamillaria (Coryphantha and Lactescentes). ‘“‘Always”’ is a dangerous word in this family of plants. . Some of the new species of mamillaria described by Prof. Coulter,* alternatus, brunneus, capillaris, densispinis, eschauzieri, maculatus, Pringlei, radians-pectenoides, omitted from Monog. Cact., have not been included in the Nachtrage, although the author’s attentiont was called to the matter, Such omissions, which are but examples of many others, it is . needless to say, seriously injure the value of the work.

It has been collected also at Topolobampo, Sinaloa, by Captain Porter, by Dr. Purpus not far from Guaymas, and abundantly in Northern Sonora by Mrs. Main.

A NEW CALAMINTHA. BY T. S. BRANDEGEE, Calamintha Chandleri. Stems frutescent, branching, 1 m. high, forming clumps, upper parts pubescent: leaves orbicular or broadly ovate, with truncate or cuneate base, obtuse, crenate- serrate or entire, 1 cm. long and broad, slightly pubescent on the upper face, more so on the lower: petioles pubescent, 5 mm. long: flowers single or in 2-4-flowered cymes in the axils of the leaves; peduncles and pedicels 1-2 mm. long: bracts linear- lanceolate: calyx tubular-campanulate, slightly bilabiate, 6-7 mm. long; the teeth about 1 mm. long, triangular, acuminate, those of the lower lip slightly longer: corolla 13 mm. long, pubescent outside, cream-white; the tube straight, as long as the calyx; lobes of the lower lip 3 mm. long and broad, the middle one largest, those of the upper lip short: stamens conniving in pairs: style bearing a few scattered hairs nearly its whole length.

The collection upon which this paper is based was made in - Sinaloa. August, 1904, I landed at Altata and from there went to Culiacan. The flora about this city and along the railway to Altata was collected during the months of September and Oc- tober. In November the plants growing about Cofradia and in the Cerro Colorado were collected. Cofradia and Cerro Colo- rado are east from Culiacan thirty or more miles, and near to the boundary line of the State of Durango. Cerro Colorado is a small mountain with peaks of red rock that are perhaps 2000 feet above sea level. Abundant rains fell during August, September and October, bringing forth a luxuriant vegetation and making it possible to find many species, ‘The following pages contain in addition to descriptions of new species, only names of those plants whose distribution seems worthy of note.

Acaulescent: leaves linear, 4-6 mm. wide below the middle, 3-3.5 dm. long, attenuate to each end, margins entire, more or less flocculent-pubescent: the 2-dm. long peduncle and linear-acuminate bract-leaves white with a de- ciduous tomentum: lower bract-leaves armed with short, recurved spines: flowers 10-14, in a simple raceme 6-8 cm. long; pedicels about 8 mm. long; petals twice the length of the 2-cm. long sepals: bracts nearly as long or exceeding the sepals. Growing on the ground about the summit of Cerro Colorado. The color of the flower-bracts and sepals is light red and probably the petals when fresh are also red. The species is nearest P. Jaliscana, differing in its white tomentose peduncle and raceme, longer flower-bracts and smaller flowers. ‘The specimens must have been more tomentose when young. Thalia geniculata 1, Growing in shallow ponds about Culiacan. Trophis sp. Perhaps a form of 7. Americana. ‘The spikes of pistillate flowers are 1-4-flowered. A small tree growing on Cerro Colorado. Populus dimorpha. A rough-barked tree with a trunk be- coming 2 m. in thickness, spreading branches and 20 m, or more high: leaves of the young trees linear-lanceolate, attenuate into a very short petiole, 1-3 cm. long, 2 mm. wide, serrate: leaves of older trees deltoid-ovate, long-acuminate, 10 cm. long, 7 cm. wide, crenate-serrate, truncate or cuneate at base: petioles flat- tened, 5 cm. long: pistillate aments about 7 cm. long, growing from wood of the preceding year, much exceeded by the young 198 Plants from Sinaloa, Mexico. [ZoR growth of the present year: capsule ovate-acuminate, 2-valved, 7 mm. long, opening in September. Common along the Culiacan, Humaya and Tamazula Rivers. The young trees bearing only linear leaves resemble willows, and until I saw older trees bearing also deltoid leaves was it cer- tain that they belonged to Populus. ‘Trees that bear both sorts of foliage have numerous intermediate leaf forms. ‘The aments growing from the almost leafless part of the branches gives the fruiting tree an appearance different from a typical cottonwood. All other species of the genus bloom in the early part of the year and soon mature their fruit. The wood is very soft and is brought into Culiacan to be made into boards. Staminate aments and pistillate flowers were not seen. Okenia hypogea C. & S. Leaves with sinuate margins, sta- mens, 7, peduncles elongated to 15 cm. and more. Collected on sand dunes near Altata.

A bush 2-4 meters high, glabrous throughout; dicecious: leaves ovate-acuminate, cordate, 5-7 cm. long, 3-5 cm. wide, dark green and shining, pinnately veined, the margin bearing numer- ous sessile glands; petioles 3-7 cm. long; stipules represented by sessile glands; pistillate flowers usually solitary, terminating the branches; pedicels 2-3 cm. long; calyx lobes 5, distinct to the base, foliaceous, ovate, 5mm. long, margined with sessile glands, glutinous and shining; petals ligulate, equalling the calyx, white or sometimes with a tinge of purple, distinct; disk entire; styles the same number as cells of the ovary (two with my specimens), distinct to the base and divided to the middle: capsule subglobose, 2 cm. in diameter: stami- nate flowers cymose-cory mbose, the peduncles shorter than the leaves; calyx lobes elliptical, slightly united at base; stamens 10; glands of the disk five. Common at middle elevations of the Cape Region mountains of Baja California. In general habit much resembling /. canescens of the same region, a species there also dicecious. I have plants of both species in cultivation and they thrive well in their new habitat. The - construction of the flower of /. vernicosa shows that it belongs to § Adenoropium of Benth. & Hook. My specimens of the Cape Region incorrectly named /. cordaita belong to this new species. Specimens of /. canescens from Altata are moncecious.

A plant evidently near C. caudata of the Cape Region of Baja California. Its local name is ‘‘Quadratos’’ and the fruit is said to be edible, but as is the case with many Mexican plants said to be good to eat, a good appetite is the first requisi- tion. This plant is erect, about a foot high, and bears large deltoid 3-lobed leaves. The fruit, about a dozen to each plant, 1-2 inches long, is born on a spike, is bright red, 5-angled, ovate, truncate at top and with five sharp points in place of the “tails’’ of C. caudata. It was found only in fruit and but one plant was seen with the fruit attached. At maturity the whole plant disappears and only a circle of the bright red fruit marks the place where it grew.

Bidens refracta Brandegee, is very common about Cofradia. The species was first found at Miraflores, Baja California, and the type locality is the only one known on the Peninsula, where it was probably introduced from Sinaloa, Bidens Alamosana Rose, is common on the low lands along the rivers near Culiacan. It becomes 8 ft. high and the large, orange-colored rays are conspicuous. Bidens oligantha.
