 "Gravelly banks near Jalapa, State of Vera Cruz, altitude 1,250 m. (4,000 feet). C. G. 

 Pringle, No. 8089. 1899." A second specimen, Liebmann 323, is cited but the first 

 is taken as the type. The Pringle specimen, which is in the National Herbarium, is 

 in the early branching state. The culm appears to be decumbent or creeping, sending 

 up erect branches. 



description. 



Vernal culms ascending from a decumbent, widely spreading or creeping base, 

 rooting at the lower nodes, softly villous or nearly glabrous, the nodes more or less 

 short-bearded; sheaths shorter than the internodes, villous or, especially the upper- 

 most, glabrate; ligules ciliate, 2 to 4 mm. long; blades 

 spreading, rather thick, more or less velvety-pubescent 

 or villous on both surfaces, the uppermost 5 to 13 cm. 

 long, 9 to 13 mm. wide, linear-lanceolate, subcordate, 

 the lower lanceolate, more cordate, shorter and wider; 

 panicles 4 to 11 cm. long, half to two-thirds as wide, 

 usually densely flowered, the numerous branches 

 spikelet-bearing from the base; spikelets 1.8 to 1.9 mm. 

 long, 1 mm. wide, elliptic, acute, sparsely pubescent; 

 first glume about one-third as long as the spikelet, pointed; second glume and sterile 

 lemma slightly exceeding the fruit at maturity; fruit 1.5 mm. long, 0.8 mm. wide, 

 elliptic, abruptly pointed.
