Banisteriopsis illustris sp. nov. 
Sericeous, or the upper leaf-surfaces tomentellate; stems erect, 
divaricately branched, the branches purple, glabrate; stipular 
es 6 mm. lon 
blades 2-7 cm. long, 2-6 cm. broad, ovate, abruptly eee 
nate and acute, jee Recher into the petiole, green or brownish 
above, white-silky beneath; principal conde mostly 3 pairs, 
a pee two-thirds their length, 
m b 
purple, oo thin, the margin little thickened, finely many- 
nerved, the nerves regularly arching outward; tubercles small, 
rather sharp 
“A bush, 7 ft. high; Apolo, 4800 ft., Mar. 9, 1902”’ (Wo. 62). 
No. 192, from the same locality, Apr. 15, 1902, of which Mr. 
Williams says, ‘‘A stout vine-like bush,” is the same, as is No. 165 
from the same locality, Apr. 16, 1902, of which Mr. Williams says, 
“A stout vine, trailing over bushes.” 
Rusby’s No. 511, and Bang’s No. 1365, are probably the same. 
The species is near B. argeniea A. Juss. 
Banisteriopsis Williamsii sp. nov. 
Lower leaf-surfaces and inflorescence puberulent; branches 
slender, purple, widely branched, the branches recurved: petioles 
ab m. long, bi-glandular near the summit; blades ae cm. 
long, 3-4 cm. ks oval, abruptly short-acuminate, 
lightly asce eas prominent Hieaabe ath, the venation slender, 
coarsely reticulate; See lo small, triangular-lanceolate; 
samara immature in ee ecimen, oblanceolate, nearly straight, 
purple, thin, the body Ba sharply tu tuberculat 
“Very slender, 15 ft. high; Mapiri, 1600 i Sek 15, 1901” 
(No. 809). A part of No. 484 from Tumupasa, 1800 ft., Jan. 14, 
1902, is the same. The other portion of my specimen is another 
species of Banisteriopsis, probably undescribed, but too young for 
positive determination, 
The species above described is well distinguished by its mucro- 
nate-aristate leaves.
