STANDLEY—STUDIES OF TROPICAL AMERICAN PHANEROGAMS. 453 
The writer has seen no specimens of this species. Brand refers here a 
specimen collected by Polakowsky (no. 395) between Augusta and Zapoto, 
’ Province of Cartago, Costa Rica, and one collected by Warscewicz (no. 2, 
in part) in the province of Veraguas, Panama. 
The calyx lobes are figured by Orsted as villous-ciliate, at least in part of 
the flowers illustrated, but this character is not mentioned in any of the 
descriptions.

SPECIMENS EXAMINED: 
Costa Rica: Bordes du Rio Pedregoso au Copey, alt. 1,800 meters, Tonduz 
(Inst. Fis. Geogr. Costa Rica, no. 12217). Foréts de la Esmeralda, Vol- 
cin de Barba, alt. 2,000 meters, Biolley (Inst. Fis. Geogr. Costa Rica, 
no. 7178). Bord des ruisseaux prés de chaléts de Turrialba, alt. 2,500 
meters, Pittier (Inst. Fis. Geogr. Costa Rica, no, 867). 
Well distinguished by the densely villous calyx lobes and by the form of 
the corolla. Brand! made this the type of a new section of Cobaea, which he 
called ‘“Aschersoniophila.” 
The fruit had not been seen by Brand. It may be described as follows: 
Capsule elliptic in outline, 5 cm. long, 2 cm. in diameter, acute, glabrous, 
glaucous; seeds 3 in each cell, 20 to 25 mm. long, 11 mm. wide, with very broad 
thin entire wings. 
Brand? refers here a specimen collected by Warscewicz (no. 2, in part), no 
locality being stated. Since the remainder of this number came from Veraguas, 
Panama, it is probable that Cobaea aschersoniana also should be credited to 
Panama. 
6. Cobaea viorna Standley, sp. nov. 
Stems slender, glabrous, or sparingly puberulent about the nodes; petioles 
glabrous; leaflets thin, bright green, glabrous, similar and subequal, oval to 
oblong, 25 to 50 mm. long, 10 to 18 mm. wide, acute, mucronate, unequal and 
rounded or subcordate at the base, on petiolules 4 to 11 mm. long; peduncles soli- 
tary, 15 to 24 cm. long, much exceeding the leaves; calyx segments united only at 
the base, linear-oblong, 23 to 30 mm. long, 4 to 5.5 mm. wide, acute to abruptly 
acuminate, glabrous; corolla greenish yellow, 3.5 to 4 cm. long, the tube cam- 
panulate, sparingly puberulent outside, the lobes slightly shorter than the tube, 
ovate-triangular, acuminate, erect; filaments 35 to 55 mm. long, slender, villous 
at the base; anthers yellow, 1 cm. long; capsule oval in outline, 42 mm. long, 
20 mm. wide, acute, glabrous, the cells each with 2 seeds. 
Type in the U. S. National Herbarium, no. 256782, collected between Rodeo 
and Malacate, Guatemala, altitude 420 to 1,050 meters, January 20, 1895, by 
BE. W. Nelson (no. 3745). 
Most closely related to Cobaeca lutea, but with smaller flowers, a greenish 
corolla, elongated peduncles, and longer calyx lobes. In general appearance 
the plant suggests some species of Viorna, this resemblance being due to the 
form of the buds, the appearance of the leaves, and the long peduncles.
