2. Arthrostylidium ekmanii Hitchc., sp. nov.° 
Culms climbing, slender (the main cane 2 mm thick), at first 
scabrous, becoming glabrous, the branches in fascicles at the distant 
nodes (25 cm apart), drooping, 20 to 30 cm long, these branching, 
bearing several appressed branchlets; sheaths glabrous, striate, the 
summit bearing several flexuous implicate bristles 5 to 7 mm long; 
blades (only those of the fertile branches seen) ascending, linear- 
lanceolate, glabrous except the pubescent tip, 3 to 6 cm long, 4 to 8 
mm wide, the petiole about 1 mm long; spikelets single or 2 or 3 in 
a raceme at the ends of the branchlets, 3 to 5 cm long, the usually 
4 or 5 fertile florets loosely arranged on a glabrous slightly zigzag 
rachilla (this not hidden by the florets); glumes narrow, somewhat 
unequal, the first 3 to 7 mm long, the second a little longer; lower 
lemma empty, longer than the glumes; fertile lemmas brownish 
(exposing the pale rachilla joints), 9 to 12 mm long, widest (about 
1.5 mm) about one-third above the base, gradually narrowed to an 
obtusish somewhat boat-shaped tip; palea from a little shorter to a 
little longer than the lemma, bowed out about the middle of the floret, 
flat and puberulent between the strongly compressed keels, the 
margins overlapping toward the tip; upper floret narrow, reduced.
