NEW OR NOTEWORTHY GRASSES 
about 10 cm. in length, floriferous to the base; spikelets nearly sessile 
along the branches, somewhat remote but regularly arranged, usually 
not reaching the one above and opposite, 2- to 3-flowered, or more 
rarely 4-flowered, the florets distant and zig-zag on a slender rachilla; 
glumes narrow, attenuate-pointed, i -nerved, smooth, scabrous on the 
keel, 3 to 3.5 mm. long, as long as or longer than the florets; lemmas 
somewhat compressed, scarcely keeled, 3-nerved, the lateral nerves 
faint, minutely and rather sparsely pilose, more densely pilose on the 
callus and on the inrolled margin, about 2 mm. long, the apex slightly 
bifid, the midnerve of the lower floret extending as a straight slender 
awn I to 2 mm. long; rachilla usually extending above the base of the 
uppermost floret. 
Type specimen in the U. S. National Herbarium, no. 733684, 
collected in a sandy meadow at Sanford, Florida, September 25, 1907, 
by Agnes Chase (no. 4135). 
Confined to central peninsular Florida. Other specimens in the 
National Herbarium are : Sanford, Chase 4134 ; Titusville, Chase 3999 ; 
Brevard County, Drawdy 6062 ; Bartow, Combs 1 186; Tampa, Combs 
1356; Braidentown, Combs 1334, Tracy 7102; Manatee, Chapman in 
1886. 
This species is distinguished from G. amhiguus by the ascending 
spikes and the shorter awns and from G. brevifolius by the ascending 
spikes that are evenly floriferous to the base. On the Chapman 
specimen above mentioned is a note by Dr. Chapman which says, 
"If we have two species [of Gymnopogon] then we must have three 
for I have one with 2-4 perfect flowers in the spikelet." 
WiLLKOMMIA TEXANA Hitchc. Bot. Gaz. 35: 283. I903. 
At the time this species was published it was stated that the name 
Willkommia had been applied to a group of Compositae before it was 
used by Hackel for a genus of grasses. Under the American Code as 
revised this earlier use does not invalidate Willkommia Hack. Will- 
kommia Schultz-Bip. was mentioned only as a synonym of a species 
of Senecio^^ and hence was not properly or technically published. 
The following specimens, all from Texas, are now in the U. S. 
National Herbarium: Ennis, J. G. Smith in 1897; Beeville, Smith in 
1897; Kingville, Tracy 8903; near Houston, Thurow 10; Waller, 
Thurow II in 1906; Harvester, open ''hard-pan" spot, Hitchcock 
1205 in 1906.
