SOUTH AMERICAN PLANTS. 7 
A very distinct species, both in the form of the leaf and the 
shape of the corolla; the leaves are 1} inch long, 7 to 9 lines 
broad, the petiole, which is slender and caniculate, being 
4 inch long; the lobes of the calyx are narrow, almost linear, 
and slightly hairy; the berry is red, of an oval shape, $ inch 
long, 4 inch in diameter; the seeds are flattened, with a hairy 
testa resembling that recorded in the following section, 
§ Perizoma. Corolla brevis, medio et fauce constricta, intus 
annulo carnoso lanato instructa.

I met with this species in 1825, when its details were re- 
corded by drawings from the living plant; it was also col- 
lected about the same time by Dr. Gillies, from whose speci- 
mens Sir William Hooker gave the excellent figure and 
description above quoted. I had long ago separated this 
from Atropa asa distinct genus under the name of Perizoma, 
and had prepared a drawing to exemplify it; but upon 
examining with more attention the species of the foregoing 
section that exist in Sir William Hooker’s herbarium, I was 
led to the conclusion that it is better to place it as a distinct 
section of Salpichroa, on account of the close resemblance of 
the most essential characters of the flower and the seeds ; the 
presence of the hairy perigynous ring and the different size 
and shape of the tube of the corolla not —- more than a 
sectional difference. 
This is a weak plant trailing ayiong?! gle or on : the 
ground. The stem is slender, sub-4-angular, somewhat 
flexuose. The leaves are sometimes almost glabrous, often 
slightly pubescent on both sides, with very short articulate 
hairs, the margin and petiole being ciliated. The flowers are 
usually solitary (or geminate when the axils present ternate 
leaves); they are cernuous upon slender pubescent lateral
