100 MR. G. BENTIIAM ON GRAMINE®. 
tanthus, Steud., is founded on two Australian species, most pro- 
bably of Danthonia, but which, from the evidently incorrect 
character given, it is impossible to identify without seeing the 
specimens. Crinipes, Hochst., is the Abyssinian species pub- 
lished by A. Richard as D. abyssinica, Hochst., in which the outer 
empty glumes are exceptionally shorter than the spikelet. 
Tribe XI. CHLORIDEÆ. 
This tribe is characterized amongst Poace& almost exclusively 
by the inflorescence. The spikelets are sessile in two rows iu 
unilateral spikes, the rhachis of which is neither articulate nor 
notched as in Hordeew; and the spikes, sometimes solitary and 
terminal, are more frequently several, either digitate at the end 
of, or scattered along, the peduncle or axis of the single panicle. 
The inflorescence is thus nearly that of Paspalum, whilst the 
spikelets are those of Festuce&, with the lowest or single perfect 
flower hermaphrodite, and the awns, when present, terminal and 
straight, not dorsal or twisted as in Agrostew and Avenew. The 
following twenty-seven genera are mostly, but not quite all, tro- 
pieal or subtropical; the first fifteen have one fertile and only 
rarely a second male flower in each spikelet ; the next ten have 
two or more fertile flowers; all,except a few very small genera or 
exceptional species, have the rhachilla continued beyond the 
flowers, and often bearing one or more empty glumes. The last 
three genera enumerated under the tribe are anomalous dicecious 
grasses, connecting Chloride: with the subtribe Sesleriez of Fes- 
tuceæ, but showing the inflorescence of the present tribe at least 
in the male individuals. 
1. Micnocnroa, Br., comprises three species, of which two are 
endemie in Afriea and the third widely spread over the warmer 
regions of the New as well as the Old World. They are slender 
tufted grasses with filiform leaves and single slender terminal 
spikes and small awnless one-flowered spikelets without any 
continuation of the rhachilla. 
2. SCHGNEFELDIA, Kunth, is a single tropical-African species 
with one to four erect spikes at the top of the peduncle; the 
spikelets are one-flowered without any continuation of the rha- 
chilla as in Mierochloa, but not so small; and the flowering 
glumes bearing long capillary awns, give the spikes an elegant 
crinite aspect. :
