As suggested by Hemsley, the foliage of this species somewhat resembles 
that of some of the vetches. The leaflets are much smaller than those of any 
other species. They are dark or dull green and glabrous above, but much 
paler and loosely villous beneath. The pubescence was not mentioned by 
Martens and Galeotti, and Brand describes the stems as glabrous. Our speci- 
mens, which are of the same and only collections cited by Brand, have numerous 
loose villous hairs on the stems, especially about the nodes, the pubescence 
being still more abundant on the petioles. The corolla is violet, according to 
Galeotti’s label, although this was not mentioned in the original description. 
Brand describes the stamens as “longiuscule exserta.” but in all the flowers 
examined by the writer they are well included. Martens and Galeotti state 
that the stigma is exserted, but they make no such statement concerning the 
stamens.

TYPE LOCALITY: Colombia. Brand cites a specimen collected in the Province 
of Bogotéi at 2,800 meters by Triana (no. 2180). This may be the type col- 
lection, although Memsley says the plant was collected in New Granada “ with- 
out any special locality.” 
RANGE: Colombia.

The writer has seen no specimens of this. Hemsley states that {t was col- 
lected at Ibaque on the Quindiu by Purdie, at Antioquia by Jervise, and at 
Tolima de Nevado by Goudot. 
13. Cobaea pachysepala Standley, sp. nov. PLATE 29, 
Stems stout, angulate or striate, glabrous except about the nodes, there 
sparsely villous; petioles glabrous or sparsely short-villous; leaflets equal, 
similar, 60 to 85 mm. long, 23 to 27 mm. wide, narrowly oblong, tapering from 
about two-thirds the distance above the base to an acuminate mucronate apex, 
rounded to subcordate at the base, dull green, slightly paler beneath, glabrous, 
or sparsely villous-ciliate when young; peduncles solitary, stout, straight in 
anthesis but curved or coiled in fruit, 12 to 18 cm. long; sepals united only at 
the base, lanceolate, 20 to 24 mm. long, rather abruptly attenuate, thick and 
leathery, puberulent outside near the base, finely tomentulose inside along the 
margins; corolla yellow, 5.5 to 6 cm. long, narrowed rather abruptly near the 
base, 4 to 4.5 cm. wide in the throat, finely and sparsely villous outside, the lobes 
short, 15 to 20 mm. long, rounded-ovate, obtuse, apparently erect; stamens 
about equaling the corolla, the filaments stout, villous near the apex, the 
anthers about 6 mm. long; style about 12 mm. longer than the corolla, the 
stigmas stout, 2.5 mm. long; capsule oblong-oval, 57 mm. long, 21 mm. broad, 
obtuse, glabrous; seeds numerous (about 8 or 9) in each cell, oblong-oval, 
about 2 cm. long, obtuse or rounded at the apex, subcordate at the base, broadly 
winged.

It is difficult to tell with which of the previously described species this should 
be compared, for it is not very closely related to any of them. Perhaps it is 
nearest Cobaca triflora, but it differs widely in the size and form of the leaflets, 
as well as in the numerous seeds. The leaflets are different from those of any
