N.S. Wales. Port Jackson, U. S. Exploring Expedition ; “an introduced

The species is dispersed over the tropical regions both of the New and the Old 
World, chiefly near the sea. 
11. XEROCHLOA, R. Br. 
Spikelets with 1 terminal hermaphrodite flower and frequently a 
male one below it, few in a short simple or branched spike almost 
enclosed in distant sheathing bracts along the main axis of the panicle, 
with a bract under each branch or spikelet. Glumes 4, thin, the outer 
one short, the 2nd longer, the 3rd the longest with a large very promi- 
nently 2-nerved palea and often 3 stamens. Terminal flowering glume 
shorter and very thin. Palea broad, closely enveloping the flower and 
ut. Styles united almost up to the rather long plumose stigmas. 
Grain enclosed in the thin palea, free from it. 
The genus is limited to Australia.

barbata, with a similar habit and foliage. The flowering bracts appear 
to be rather narrower and more distant, more frequently terminating 
m a point or lamina, Spikes branched, with 5 or 6 spikelets on each 
branch, but the whole not much exceeding the outer bract. Glume 
and pale: as in X. barbata, except that they are all glabrous.—F. Muell.
