14 PANICACE^. 



nodia 0, Styles very long, filiform, bifid. Grain enclosed with 

 the internodes of the rachis, not adherent.

 spikes racemose, each enclosed in long bracts. The affinity to Zea 

 appears to be recognized even by those not botanists, as in its 

 native country it is known as "Wild Maize." 



Leaves much like those of Maize. Species 3, or perhaps 1 species 

 and 2 varieties, all belonging to Mexico.
