Thalictrum peninsulare (Brandegee) Rose. 
Thatictrun resiculosum peninsilare Brandegee, Zoe 4: 399. 1894, 
Mr. Brandegee describes it as follows: 
“ Thalictriun vesiculosinin Lee. var. peninsulare. Plants about 1m. high, glabrous 
throughout, excepting a minute glandular pubescence on the margins of the sheaths, 
somewhat glaucous; stems striate: leaves tripinnate, distant; leaflets slender-petio- 
ulate, thin, sometimes 3 em., but ordinarily less than 2 cm. long, green above, glau- 
cous below, spatulate, ovate or obovate, 3 to 6, commonly, 3-lobed at apex, the lobes 
entire; panicle loose and spreading somewhat leafy; pedicels elongated, filiform: 
flowers usually hermaphrodite; sepals 4, 2 mim. long, oblong-elliptic or oval, pur- 
plish, with conspicuous parallel veins; filaments filiform, flexuous, more or less dilated 
toward the top, in full development exceeding the linear 4 to 5 mim. long, mucronate 
anthers, ovaries about 5, stipitate; style filiform 6 to 8 mm. long, strongly papillose 
on the back, tapering to the extremity, stigmatic nearly the whole length, the thin 
margin rolled in; heads nodding in fruit, akenes 5 to 6 mm. long, usually concave on 
the inner angle, stipitate, tipped by more or less of the base of the style, the flat- 
tened sides and back strongly veined and nodulose.—Common at middle elevations 
in the mountains of the Cape Region. 
“This plant is geographically so far removed from the South American type that 
comparison of specimens may show them to be specifically distinct.” 
Thalictrum jalapense Roze, sp. noy. 
Stems 9 to 10 dim. high, glaucous; leaves 3 or 4 ternate; leaflets small, nearly orbic- 
ular, 1 fo 1.5 em, in diameter, glabrous above, pubescent by short papillose hairs 
beneath, few-toothed, strongly cordate at base; inflorescence paniculate; sepals pur- 
plish, somewhat glandular; stamens long, mucronate-tipped; akenes small, strongly 
reticulate-nerved. 
Collected by J. N. Rose near Jalapa, August 17, 1901 (no. 6188). 
This species comes near 7. strigulosum Hemsley, but has smaller leaflets and these 
glabrous above, glandular sepals, ete. It is also found at much lower altitudes. 
Thalictrum stipitatum Rose, sp. noy. 
Stems 18 to 30 em, high and closely resembling 7. obliqniin, except that the leaf- 
lets are even smaller and often entire, at most with a single tooth on a side, and the 
akenes more tapering at base, forming a very decided stipe. 
Collected by C. G. Pringle in a wet barranea above Cuernavaca, altitude 1,950 
meters, September 21, 1896 (no. 6511), and distributed as 7. gibbosum. 
Thalictrum subpubescens Rose, sp. nov. 
Rather stout, 9 to 15 dm. high, with glabrous or glabrate stems; leaves large, broad 
in outline, 3 or 4 times ternate, the rachis and under surface of leaflets softly pubes- 
cent; leaflets orbicular, rather large, 2 to 3 em. in diameter, with a few rounded 
teeth, glabrous above; inflorescence panicalate; anthers long-apiculate; akenes 
strongly reticulated. 
Collected by C. G. Pringle on moist banks in Sierra de las Cruces, altitude 3,000 
meters, August 14, 1896 (no. 6414). 
Perhaps nearest 7. tomentellum Rob. & Sea., but stouter, with larger leaflets, these 
glabrous above, ete. 
BRASSICACEAE. 
NEW SPECIES OF DRABA. 
Heretofore only four species of Draba have been known from 
Central Mexico. The five new species here proposed have been 
repeatedly compared with the descriptions of these old ones. Several
