Panicum stenodes Griseh . Fl. Brit. ¥7. Ind. 547. 1864. "Hab. Jamaica!, Pd. [Purdie], 

 in savannahs, Manchester." The type specimen, bearing data as published, is in 

 the Kew Herbarium. 



Panicum Mans Spruce; Griseb. Fl. Brit. W. Ind. 548. 1864, not Ell. 1816. This 

 name is given as a synonym of P. stenodes and credited to "PZ. Spruce." We have 

 not seen Spruce's specimen and the name is here referred to P- 

 stenodes on the authority of Grisebach. 



DESCRIPTION. 



Plants in small tufts, 25 to 50 cm. high, glabrous throughout; 

 culms erect or reclining, very slender and wiry, producing 

 from the middle nodes slender branches about equaling the 

 main culm, both this and the branches bearing small, solitary 

 or fascicled panicles from the upper nodes; sheaths very short, 

 about 1 to 2 cm. long; blades 1 to 4 cm. long, 1 to 2 mm. wide, 

 the upper often reduced to mere points, erect, firm, involute; panicles short-exserted, 

 the lateral often partly included, 1 to 2 cm. long, 1 to 2 mm. wide, subracemose; 

 spikelets 1.4 to 1.6 mm. long, about 0.7 mm. wide, elliptic, rather turgid; first glume 

 about half the length of the spikelet, blunt, nerveless or 1-nerved; second glume 

 and sterile lemma equal, scarcely exceeding the fruit, 5-nerved; fruit 1.3 mm. 

 long, 0.6 mm. wide. 



This species is distinguished from P. tenerum by its more slender culms, numerous 

 branches, and smaller panicles of smaller spikelets.
