PuNGO AxDOX(;o.. — An annual, erect herb ; leaves membranous, 

 curved ; flowers yellow. In moist places planted with manioc, near 

 Calunga, at the sides of the river Mi^ge ; fl. and fr. April 1857. 

 No. 5849. An annual, erect herb, simple below, alternately branched

This species has been united with M. sessiliflorum by 0. Kuntze, 

 Rev. Gen. PL iii. 2, p. 237 ; he calls both Nigrina sessiliflora. Our 

 plants are doubtfully placed here and should be compared with the form 

 suhpetiolatum (O. Kuntze, I.e., p. 238), the type of which I have not seen. 



3. M. rigidum Hiern, sp. n.

 12 in. high, branched from the base or simple ; stem rigid, more 

 or less hispidulous ; branches erect or ascending, rather slender
