Campulosus floridanus n. sp. 
A perennial with short creeping scaly rhizomes; culms erect, 
puberulent or scaberulous below the inflorescence, otherwise glabrous, 
60 to ICQ cm. high; sheaths glabrous, the basal numerous, becoming 
fibrous with age; ligule a more or less lacerate membrane, the upper 
acute, 2 mm. long, the lower shorter; blades firm, mostly becoming 
involute, attenuate at apex, glabrous, 10 to 15 cm. long, the upper- 
most shorter, i to 3 mm. wide; spike long-exserted, single, erect, 
straight or somewhat curved, often twisted, 8 to 15 cm. long, the 
outer side of the rachis smooth and rounded, the margins somewhat 
incurved; spikelets densely imbricated, pectinate, consisting of 2 
glumes, 2 sterile lemmas, a fertile floret and i or 2 upper reduced and 
sterile florets; glumes unequal, the first lanceolate, acuminate, i- 
nerved, thin, 2 mm. long, the second firm, acuminate, ridged with 2 
nerves, the third nerve weak, smooth or scaberulous on the nerves, 
about 6 mm. long, the awn slightly below the middle, straight and 
divaricate at maturity, about 5 mm. long, tuberculate at base; first 
sterile lemma about 3.5 mm. long, long- villous on the base and margjns, 
bifid at apex, with a straight awn from between the lobes, reaching 
about the apex of the fertile floret, the palea wanting; second lemma 
similar to the first, but with longer awn and villous chiefly above the 
middle, the palea well-developed; fertile lemma about 5 mm. long, 
sparsely villous above the middle, awnless, the palea nearly as long; 
reduced floret not as long as the spikelet, sometimes with a second 
smaller rudiment above.

This species has been referred to C. chapadensis Trin. of Brazil. 
That differs in having scabrous sheaths and blades and usually 2 
flexuous spikes, in the tuberculate second glume roughened on the 
midnerve, and in the more densely villous florets. 
Gymnopogon Chapmanianus n. sp. 
A cespitose somewhat purple perennial; culms erect or stiffly 
ascending, 25 to 40 cm. high; leaves mostly towards the lower part of 
the culm; sheaths glabrous, striate, more or less inflated, strongly 
overlapping; ligule a very narrow ciliate-margined membrane; blades 
flat, smooth beneath, scaberulous above, scabrous on the margins, 
rather leathery, stiffly spreading, abruptly narrowed or somewhat 
cordate at base, pungently pointed, 4 to 7 cm. long, 4 to 6 mm. wide; 
panicle fan-shaped, consisting of numerous slender, straight, ascending 
branches about 15 cm. long, arranged along a sulcate, scabrous axis
