NAZIEHZ—MELINIDE A 175 
a short spike. The allied genus Pleuraphis furnishes a 
few important forage grasses in the Southwest. Pleura- 
phis Jamesi Torr., is called galleta in New Mexico, a 
name which is applied in California to P. rigida Thurb. 
Other grasses of interest belonging to this tribe are 
Nazia, one species of which, N. aliena (Spreng.) Scribn. 
extends from the tropics into Arizona, and Osterdamia 
(Zoysia), one species of which O. matrella (L.) Kuntze 
(Zoysia pungens Willd.), the Japanese or Korean lawn- 
grass is occasionally cultivated in California, and along 
the seacoast of the south Atlantic states. The first 
mentioned genus is peculiar in that the fascicles of 3 to 5 
spikelets form a bur, the second glume of each spikelet 
being provided with hooked spines. In Osterdamia the 
spikelets are single instead of in groups. 
TripeE IV. MELINIDE (TRISTEGINE) 
213. This is a small tribe of about 8 genera, none of 
which is represented in the United States. The spikelets 
are borne singly in panicled racemes with a continuous 
axis. The most important genus is Arundinella, reed-like 
grasses, several species of which are found in tropical 
America.
