little shorter than the spikelet, very minutely scaberulous at the tip, 
5-nerved, the midnerve evident only at the tip, the intermediate 
pair indistinct, the lateral pair distinct near the margin on the ventral 
side of the floret, the margins of the lemma ap- 
proximate but not in contact along the middle of 
the face; palea nearly as long as the lemma, scab- 
erulous like the lemma at the acute tip, convex on the 
back, the 2 nerves wide apart, the apex enclosed at 
the tip (fig. 225). 
Type in the United StatesNational Herbarium, no. 
1387466, collected along the edge of the Rio Piloto, 
at 300 m altitude, Sierra de Nipe, proy. Oriente, Cuba, 
September 8, 1922, by E. L. Ekman (no. 15045). 
The species was collected by Dr. Ekman (no. 
10085) at the same locality, October 19, 1919, grow- 
ing in moist sloping ‘“manacales”’,® but the speci- 
mens are sterile. The species is said by Dr. Ekman 
to be very rare. It is named for M. K. Beyer, a 
Norwegian, who accompanied Dr. Ekman on many 
Sierra de Nipe excursions. 
The species is not closely allied to any other, but 
for convenience is assigned to the group Tenera in 
which the culms are stiff and wiry. In habit it 
resembles P. distantiflorum, but the branches of the 
Ficure 225—Pani- panicle do not end in a bristle, but frequently bear 
fan stineniote 1x abortive spikelets, suggesting a trend toward elimi- 
Fea pauen of the spikelet, as in P. distantiflorum and 
its allies.

Florida. 
Culms erect, 1 to 2 m tall; lower sheaths, especially on the innova- 
tions, compressed-keeled; blades flat from a usually folded base; 
panicles condensed, terminal and axillary, 10 to 25 cm long, rarely 
over 5 cm wide, the long solitary or fascicled 
branches erect, naked at base, with appressed 
branchlets bearing crowded spikelets on short 
pedicels; spikelets about 2.5 mm long, glabrous, 
acuminate (fig. 226).
