Plate 20. Panicum miliiforme Presl. Luzone. — a, View of spikelet, 
showing first glume; b, view of spikelet showing the second glume; ¢, 
anterior view of third glume showing its palea; d, dorsal view of flower- 
ing glume; e, dorsal view of palea, which is partly inclosed by the 
flowering glume. 
Plate 21. 1, Panicum phleiforme Presl. Mexico. Specimen frag- 
mentary.—a, View of spikelet showing first glume and a part of third; b, 
view of spikelet showing second glume from the back; c, lateral view of 
spikelet; d, dorsal view of flowering glume; e, anterior view of same 
showing palea. 2, Panicum polyrrhizum Presl. Monterey, Cal. —a, View 
of spikelet showing first glume; b, view of spikelet showing second 
glume; c, dorsal view of flowering glume; d, anterior view of first 
spikelet, the outer glumes removed showing palea; e, inner view of palea 
showing lodicules and stamens. 
Plate 22. Panicum stipatum Presl. —a, Spikelet showing very minute 
first glume; b, spikelet showing second glume; c, back of flowering 
glume; d, opposite face of flowering glume with inclosed palea, showing 
also attached palea of third glume. 
Plate 23. Alloteropsis distachya Presl. Monterey, Cal.—a, Spikelet 
showing first glume; b, view of the spikelet showing second glume; c, 
anterior face of second glume; d, palea, lodicules, and stamen of the 
staminate flower; e, fertile flower. —f, Joint of a rachis, a sessile spikelet 
and a pedicel of a pedicellate spikelet of some species of Andropogon. 
This spikelet, from which this drawing was made, was found only in 
one instance, inside the third glume, occurring there through some 
accident doubtless. It was upon this supposed compound spikelet that 
Presl based his genus Alloteropsis. The grass, however, is a species of 
Panicum.

spikelet; b, inner view of third glume showing its palea; c, back of 
flower; d, anterior view of same.
