6. Arthrostylidium distichum Pilger, in Urban, Symb. Antill. 2: 342. 
1901. 
Branches solitary or in small fascicles; culms slender, a line of 
pubescence on one side, the nodes pubescent; sheaths bearing at 
summit several stiff bristles 5 to 15 mm long; blades approximate, 
regularly spaced, dorsiventral, lanceolate-acuminate, glabrous, sca- 
brous on the margins, 1.5 to 3 cm long, 4 to 6 mm wide; spikelets 8 
to 15, 1 to 2 cm apart. 
The type collection, Wright 3808, bears imperfectly developed 
spikelets. ‘The only other collection with spikelets is Ekman 10946 
and this also bears abortive spikelets. All the spikelets are reflexed 
above the base. A few spikelets of the Wright collection have two 
florets about 5 mm long above the empty glumes. 
Rocky banks, Cuba and Hispaniola.

Branches solitary, appressed or slightly spreading; blades often 
reflexed, rather rigid, 5 to 10 cm long, 4 to 6 mm wide; racemes 15 
to 30 cm long, the spikelets appressed, more or less imbrieate or 
somewhat distant, the axis straight; spikelets usually with two per- 
fect florets and a terminal narrow imperfect one; lemmas short-awned. 
At upper altitudes plants not more than 30 to 100 cm tall.

appressed, the floriferous ones 25 to 35 cm long, bearing several 
leaves on the lower 15 cm; sheaths glabrous, somewhat cross-veined 
6 Culmi graciles, ramis solitariis vel paucis appressis; vaginae glabrae, apice setas paucas 3-5 cm longas 
ferentes; laminae glabrae lineari-lanceolatae 5-15 cm longae 7-10 mm latae; panicula angusta gracilis elon- 
gata 10-20 cm longa; spiculae circa 6 mm longae reflexae.
