Also in Tropical America from Mexico to Brazil. The varieties proposed by 
Hackel in his monograph of the Andropogonece represent hardly more than 
ordinary fluctuations. 
Franchet described the sessile spikelets as ? , having evidently overlooked 
the very small anthers. It is very doubtful whether they ever become exserted 
from the spikelets, as are the long narrow stigmas. It may be that these spike- 
lets behave like cleistogamic flowers during the earlier stages of flowering. The 
anthers, small as they are, contain pollen which is apparently quite sound.

Spikelets 2-nate, one sessile, the other pedicelled, similar in shape, 
different in sex, on the fragile rhachis of many-jointed solitary 
spatheate racemes which are frequently gathered in fastigiate 
bundles, rarely the lowermost 1-3 pairs homogamous ; joints and 
pedicels filiform, compressed, solid or slightly grooved, disarticulating 
horizontally ; spikelets deciduous, the sessile with the adjacent 
joint and pedicels. Florets 2 in the fertile spikelets, the lower
