generic name is derived by Mr. Miers from iffy down, and *xa8o f 

 a slender stem, in allusion to the character of some of the species. 

 The genus includes a very natural group of Solanea, mostly na- 

 tives of Peru and New Grenada, and all from South America. 



Descr. This is usually stated to be a shrub, but the specimen 

 sent to me is so green and succulent, that it is probably at most 

 suffruticose ; branches more or less spreading, terete, glabrous. 

 Leaves, the lower ones solitary and alternate, upper ones in un- 

 equal pairs, subovate, shortly petiolate, acute, sinuate, often angu- 

 lato-dentate, glabrous, paler and with prominent nerves beneath. 

 Peduncles axillary, solitary, forked or trifid, bearing two (rarely 

 three) handsome, drooping/oows. Calyx glabrous, rotate, with 

 five spreading acute waved segments. Corolla an inch or more 

 long, of two colours ; the tube conico-cylindrical, purple, hairy, 

 striated; the limb of five spreading, green, narrow-lanceolate 

 segments, with a small tooth in each sinus. Stamens from the 

 base of the corolla, much exserted. Filaments hairy at the base. 

 Anthers blue-purple. Ovary globose, sunk in a two-lobed fleshy 

 disk. Style as long as the stamens.
