40 _ PENTANDRIA DIGYNIA. Asclepias. 
The Hindoos make two species of this plant on ac- 
count of the variety of the leaves; and I long thought 
they were so, till searching more narrowly, and taking up 
many of the roots. I then frequently found every varie- 
ty of the leaves on different branches, issuing from the 
same root ; which confirmed me in their being one plant. . 
This is probably what Retz calls name P. Emetica but I 
am pretty clear Dr. Konig did not give it that name. To 
the best of my remembrance, he always conceived the 
broad leaved to be P. Indica, and the narrow to be Cero- 
_ pegia tenuifolia, The plant sometimes employed as.a 
substitute for Ipecacuana, is what Konig described un- 
der the name Asclepias vomitoria; a drawing and des- 
cription of it will be found in my collections, viz. N. 608. 
Asclepias asthmatica, The roots, whether dried or fresh, 
have a pleasant, peculiar fragrance, which I cannot des- 
cribe, 'Yhey are known on the Coromandel coast by the 
name. of country Sarsaparilla ; and as such were often 
employed by our Medical Gentlemen. |The natives em- 
ploy them in medicine more than we do, particularly for 
the thrush in children, For this disorder the dried bark is 
reduced to a fine powder, and fried in butter; the propor- 
tion uncertain, as is often the case with Hindoo prescrip- 
tions, the quantities being in general guessed ; about a 
dram of this is given, night and morning. They are also 
employed, with some other roots in the cure of venereal 
complaints,
