Busbeckia, sp. Mart. MSS. 
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 Afropa as a 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 offering more than a 
Sectional difference. 
This is a weak plant trailing among bushes, 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 
irs, the margin and petiole being ciliated: The flowers are 
usually. solitary (or geminate when the axils. present ternate 
ves); they are cernuous upon slender pubescent lateral 
peduncles, The calyx is deeply cleft: into 5 long sharply- 
pointed, almost linear erect segments; it is slightly pubescent 
and persistent, it does not increase much. in size nor become 
patent as the fruit ripens. The corolla is short and tubular, 
ad,in proportion, quite white and smooth, and sensibly 
contracted both in the middle where the filaments are inserted, 
as well as in the mouth; the segments of the border are 
narrow, acuminated' and reflected ; the æstivation is slightly 
induplicate, the inflected edges adhering by their woolly mar- 
8s; near the base of the tube is seen a somewhat fleshy 
"ng, which is covered with long, woolly, white, articulated 
The stamens are equal, short, slender, and glabrous ;
