354 Mr. Coleerooke's Description 



by Gfertner Pi/geii>n. 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 

 uhich he named Pi/geum zeylanicum. It seems prudent, how- 

 ever, to give provisionally a distinct trivial name to a plant, 

 w'hich most probably is specifically different. 



Two plants of the natural order of the Jsclepiadece have been 

 selected for 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 Tybphora ; 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 may be de- 

 signated Vu'dpa bijuga.
