The above generic character is another of the contribu- — 
tions from the pen of Mr. Brown, which we have been so a 
fortunate as to be the means of imparting to the public. 
To those who are aware of the vast store of knowledge from 
which the various groups for the use of science are com- 
bined by that eminent naturalist, the circumspection and 
sagacity with which they are adopted, and the accuracy with 
which they are defined, no appreciation of ours can be ne- 
cessary to enhance the value of the present we now offer in 
the three genera constituted and defined by that masterly 
hand in this fasciculus. 
Cryprostsara is founded upon a single species, native of 
the peninsula of India, where it was first observed by Dr. 
Roxburgh and strangely mismatched by him with the species 
of the genus Nerium, belonging to the Apocynew ; while our 
plant belongs to the third section of Mr. Brown’s Asclepi- 
adew, distinguished from the other sections by granular 
solitary pollen-masses and filaments which are distinct in 
whole or in part. CryprosreGia is however conceived by 
Mr. Brown to be the link by which the two orders connect 
through his genus Crypro.eris also a native of India and 
a climber. :
