Orthoclada rarifiora Beauv. Ess, Agrost. 69. pl. 14. f. 9. 1812. 
A stoloniferous perennial; flowering culms ascending, leafy, simple, commonly 
1 meter long; blades slender-petioled, lanceolate, mostly 12 to 15 em. long, about 
2.5 cm. wide; panicle large, as broad as long, the long slender naked branches 
and capillary branchlets at first erect, finally stiffly divergent, bearing 1 to few 
spikelets at the extremities. 
Rich woods, southern Mexico to Brazil; also in Guadeloupe and Trinidad. 
Originally described from Cayenne. Panicum rariflorum was also described 
from Cayenne. 
96. STREPTOGYNE Beauv. 
Spikelets several-flowered, subsessile in a long one-sided raceme; glumes 
unequal, much shorter than the elongate terete callus-tipped florets; lemmas 
firm, tapering into a slender awn; palea about as long as the lemma; stigmas 8, 
elongate, persistent, coiled, the mature fruits hanging by these entangled stigmas. 
1. Streptogyne crinita Beauv. Ess. Agrost. 80, pl. 16. f. 8. 1812. 
An erect perennial, 1 to 1.5 meters tall, with elongate leaves mostly aggregated 
at the base and reaching beyond the base of the inflorescence, the blades 1 to 1.5 
em. wide, and a slender spike 80 to 50 cm. long, the axis rather firm, the short- 
pediceled slender spikelets appressed, about 3 cm. long, excluding the slender 
awns and curled stigmas. 
Rich woods, Veracruz and Trinidad (Tabaquite, Caparo Forest) to Brazil. 
“ Carolina,” the locality given with the original description, is an error. Beau- 
yois also mentions Guiana. 
97. UNIOLA L. 
Spikelets strongly compressed, few to many-flowered, the lower 1 to 4 florets 
empty; glumes and lemmas keeled, firm, the glumes small, the lemmas faintly 
many-nerved ; paleas rigid, the keels broadly winged. 
Spikelets 8 to 10 mm. broad, in a drooping panicle__._________ 1. U. paniculata. 
Spikelets less than 2 mm. wide, closely aggregated in numerous spikes, forming 
a long narrow erect inflorescence_ _.-2 U. virgata.
