954 . Mr. CoteBrooxe’s Description 
by Geertner Pygeum. Nothing more of his plant was seen by 
him besides the fruit; and as no marked difference sufficient to 
discriminate the species is presented in the mature fructification, 
it is possible that the species now described may be the same 
which he named Pygeum zeylanicum. It seems prudent, how- 
ever, to give provisionally a distinct trivial name to a plant, 
which most probably is specifically different. 
Two plants of the natural order of the Asclepiadeæ have been 
selected fur insertion in the present communication: the first of 
them, a species of Dischidia; only one species of that genus 
having been hitherto described. It was figured by Rumphius, 
being native of the Molucca islands. ‘The present sort is indi- 
genous in the north-east of Bengal: and the ingenious botanist, 
by whom the genus was constituted, has intimated, that India 
possesses other species of it not yet examined in a perfect state *. 
Another plant now described is a Tylophora; in which genus the 
specific characters of eight sorts have been established by its 
author: but none I believe have been delineated by figure. — — 
One more plant of a known genus is here described; and, in 
deference to authorities of the Linnean school, under the generic 
name of Macrolobium. I should be disposed, however, to follow 
Lamarck in separating very dissimilar plants, which Schreber has 
collected into one group. If this be allowed, and Lamarck's ge- 
neric name be retained, the plant now described net: be de- 
signated Vudpa bijuga.
