This is a small tribe, numbering' only sixteen species 

 classed in seven genera. They are nearly all natives 

 of the Tropics, chietly in the Old World. Indian corn,

Trihe II. — Andropogone(F. 



Spikelets in spike-like racemes, two at each joint of the articu- 

 late rachis, one sessile and hermaphrodite, one pedicellate, the 

 latter hermaphrodite, staminate. neuter, or reduced to the pedicel 

 alone: glumes usually four, the first and second empty, larger 

 and much firmer in texture than the others, the third usually 

 empty, with a staminate flower in its axil, very rarely awned, the 

 fourth or flowering glume hyaline, usually awned, awn usually 

 twisted or geniculate. 



This tribe contains about four hundred species divided 

 amou,ii: twenty-nine genera, of which the genus Andropo- 

 gon. with one hundred and ninety species, is by far the 

 largest and probably the most important. Sugar cane 

 belongs to this tribe in the genus Saccharum. Our best 

 known representatives of the Andropogoneje are the 

 common broom sedge. Andropogon virgin iciis. and the 

 big blue stem. Andropogon prorinciaUs. In the same 

 genus are now classed our species of sorghum. The 

 members of the tribe are distributed throughout the 

 tropical and warmer regions of both hemispheres.
