Tylophora.'] AsclepiadcCB. 1 59 



Roots many, long, fleshy ; stems very long, slightly 

 branched, strongly twining, pubescent or hairy ; 1. 1-2J in. 

 (larger on main stem), oblong-oval or rotundate, cordate or 

 rounded at base, suddenly and very shortly acuminate or 

 apiculate, nearly glabrous above, more or less densely 

 pubescent beneath (at least when young), petiole \-\ in., 

 pubescent; fl. large (for genus), on very long, hairy, filiform 

 ped., numerous, in 2 or 3 nearly sessile umbels at end of short 

 peduncle, bracts filiform, hairy ; cal.-segm. lanceolate, very 

 acute, coarsely hairy; cor. \ in. diam., lobes ovate, acute, re- 

 curved ; column prominent, coronal processes gibbous below, 

 abruptly narrowed into free points; follicles 2-3^ in., divaricate 

 or deflexed, slender, fusiform, glabrous; seeds \ in., broadly 

 oval, coma f in. 



Low country, chiefly in the moist region up to 4000 ft.; rather common. 

 Fl. Sept.-Feb. ; greenish-purple. 



Also in India, Burma, Malaya, and Mauritius. 



There is a specimen (without ticket or number) in Hermann's 

 Herbarium and two drawings, but the plant was not taken up by 

 Linnteus. Linn, f.'s description was from Ceylon specimens of Koenig's, 

 whose (MS.) name, Asclepias voiniforia, is frequently given by old 

 authors. Cynanclnan bracteatum^ Thunb. Cyn. 7, may be this. Her- 

 mann's S. name, ' Manughawjel,' would be now written Maha-nuga-wel. 



The root is a valuable medicine, possessing all the properties of 

 Ipecacuanha, and is often called by that name. The leaves also have 

 the same properties, and are an official drug in the Indian Pharma- 

 copoeia.
