long, purplish red, villous at the base, the anthers yellow, 15 to 20 mm. long; 
style filiform, green, longer than the corolla, the stigmas slender, 1 cm. long; 
disk thick, 5-lobed, the lobes again 2-lobed; ovary 3-celled; fruit not known. 
The type of this species is plate 5757 of Curtis’s Botanical Magazine, the 
present description being drawn from the plate and from the accompanying 
description by Hooker. The plant figured was grown at Kew from seeds sent 
from Caracas, Venezuela, by Mr, A. Ernst. It flowered in the Palm House of 
the Royal Gardens in December, 1868. The same illustration is reproduced by 
Hemsley as a text figure in volume seventeen of The Garden, page 353. 
As soon as one places Hooker’s plate beside the excellent one of Rosenbergia 
pendulifiora published by Karsten, it is obvious that two very different plants 
are represented. Cobaea hookeriana differs from Karsten’s species in the less 
acute leaflets, longer, glabrous calyx lobes, larger corolla, broad, bifid, pale green 
corolla lobes, acute sinuses, short stamens, and elongated stigmas. The fact 
that both plants come from Venezuela means nothing, when one considers the 
number of species of the genus found in Guatemala. Although the seeds from 
which Hooker’s plant were grown were sent from Caracas, they may have come 
from some locality far distant from that city. 
As stated under Cobaea pendulifiora, Brand cites the Botanical Magazine plate 
as that species, although his description excludes it. Hemsley’ attempts to 
reconcile the differences between the iwo plates, apparently, stating that the 
length of the stamens and the color of the corolla is variable,

3. Cobaea panamensis Standley, sp. nov. PLATE 27. 
Stems very slender, glabrous, purplish green; leaflets subequal, narrowly 
oblong to oblanceolate, 6 to 8 cm. long, 15 to 25 mm. wide, abruptly acute or 
acuminate, oblique and rounded to subcordate at the base, thin, glabrous, 
bright green, slightly paler beneath; petiolules 4 to 8 mm. long; peduncles 
solitary, pendulous, slender, 15 to 21 cm. long; calyx lobes united only at the 
base, glabrous, green, linear-lanceolate, 25 to 35 mm. long, long-attenuate; corolla 
deep brownish purple, the tube campanulate, 18 to 20 mm. long, with acute 
sinuses, puberulent outside, glabrous within, the lobes 6 cm, long, 5 or 6 mm. 
wide at the base, tapering to the long-attenuate tips; filaments very slender, 
purple, 9 to 11 cm. long, much exceeding the corolla, villous at the base; anthers 
purple, 1 em. long; style slender, 10 to 13 em. long, glabrous; stigmas slender, 
8 mm. long; immature capsule elliptic, acute, glabrous. 
Type in the U. S. National Herbarium, no. 677661, collected in sunny but cool 
places, between the Rio Ladrillo and Los Siguas Camp, southern slope of Cerro 
de la Horqueta, Chiriqui, Panama, altitude 1,200 to 1,700 meters, March 18, 1911, 
by H. Pittier (no. 3270). 
From the other species with much elongated and very narrow corolla lobes, 
this may be distinguished by the deep purple corolla with long-attenuate lobes. 
It is most closely related to Cobaea pendulifiora, but differs in the narrower, 
long-attenuate, glabrous calyx lobes, acute sinuses of the corolla, and dif- 
ferently shaped leaflets.
