 on roadsides, etc. (Panama, Cuminc/, n. 1092; Bahia, 

 Gardner^ n. 889,) and frequently cultivated, and perhaps 

 sometimes naturalized in E. India, ( Wallich. Cat. n. 4292 ; 

 Philippine islands, Cuming, n. 1261, and 1372 J). — It varies 

 much in hairiness; the smoother forms are the M. pudica, 

 Kunth, or M. pudlhunda, Willd., the more hairy are the iSI. 



pudica^ Linn., Willd., or M. Tuspidida, Kunth. 



31. U. Endgmionis {Mnvi. Herb. Fl. Bras. 131.), from 

 the interior of the province of Bahia, is unknown to me; but 

 from his description, I am unable to see how it differs from 

 the smoother forms of '^l. pudica. 



32. M. polydactyla (Humb. et Bonpl. in Willd. Spec. 

 iv. 1033.), suflfruticosa, aculeis infrastipularibus sparsisque re-
