or nearly so, about 2.5 mm long, in pairs, the longer pedicel 2 to 3 
mm long; first glume obsolete or wanting; second glume as long as 
the spikelet, obtusish, 3-nerved; sterile lemma as long as the spikelet, 
acute, 5-nerved ; fertile lemma as long as the spikelet, pale, acute. 
Type in the United States National Herbarium, no. 1161280, col- 
lected in wet places in pinelands, Herradura, prov. Pinar del Rio, 
Cuba, June 26, 1922, by E. L. Ekman. 
This species has been referred to °° Syntherisma simpsoni (Vasey) 
Nash, of Florida, which differs in having spikelets 3 mm long, the 
second glume and sterile lemma 7-nerved. 
The type specimen has glabrous spikelets. In the other two speci- 
mens cited the spikelets are minutely pubescent along the nerves.

Spikelets embedded in one side of an enlarged and flattened corky 
rachis disarticulating at maturity, the spikelets remaining attached; 
first glume small; second glume and sterile lemma about equal, the 
latter with a palea or staminate flower; fertile lemma chartaceous. 
Stoloniferous perennials with short flowering culms, rather broad 
short obtuse blades, and flat terminal and axillary racemes.

Extensively creeping, the flat stolons with long internodes and short 
leafy branches, the sheaths equitant; flowering culms 10 to 30 cm 
tall, the blades commonly 10 to 15 cm long; racemes 5 to 10 cm long; 
spikelets 4 to 6 mm long (fig. 113). 
Open grassland, at low altitudes, especially near the coast, southern 
United States to Argentina. An excellent pasture grass. Used for 
lawns in loamy or mucky soils. In Cuba called ‘‘camalote’’, ‘‘cam- 
bute’, “gramon de costa’, and ‘“‘caflamazo amargo.”’ Bermuda 
Islands and Bahamas to Trinidad and Tobago; to be found on prob- 
ably all the West Indian islands.

Inflorescence a single terminal spikelike raceme, the rachis usually 
with membranaceous wings, partially embracing the row of spikelets; 
spikelets apparently subsessile and solitary in a single row, but 
actually in pairs, the spikelets of each pair back to back, the pedicel
