Panicum lindheimeri Nash, Bull. Torrey Club 24: 196. 1897. “The type was col- 
lected by F, Lindheimer in 1846, no. 565.’’ The type, in Nash’s herbarium, consists 
of two rather slender vernal culms geniculate at the lower nodes, sparsely papillose- 
pilose below, beginning to branch at some of the nodes, No locality other than 
Texas is given on the label of the type nor on that of Lindheimer 565 in the National 
Herbarium, but on that of another specimen of this collection in the herbarium of 
the Missouri Botanical Garden the following data are given: ‘‘Springs, banks of the 
Guadeloupe, near New Braunfels.”

‘‘Type specimen collected on the bank of Kaweah River at Three Rivers, Tulare 
County, Cal., no. 1286, Coville & Funston, July 26, 1891.’? The type, in the National 
Herbarium, consists of two branching culms, one sending out a rootlet at the second 
node (indicating that the culm was prostrate); sheaths and lower internodes rather 
strongly papillose-pubescent. 
This is the species described under P. nitidum Lam. in Britton’s Manual.¢ 
DESCRIPTION. 
Vernal culms stiffly ascending or spreading, 30 to 100 cm. high, glabrous, or lower 
internodes ascending-pubescent, the nodes swollen; sheaths less than half as long as 
the elongated internodes, ciliate on the margin, otherwise glabrous, or the lower 
ascending-pubescent; ligules 4 to 5 mm, long; blades usually firm, 5 to 10 cm. long, 
6 to 8 mm. wide, at first ascending, soon spreading, papillose-ciliate at the rounded 
base, glabrous on both surfaces, or minutely puberulent beneath; panicles 4 to 7 
cm. long (rarely longer), nearly as wide, branches ascending or spreading, loosely 
flowered; spikelets 1.4 to 1.6 mm. long, 0.8 to 0.9 mm. wide, obovate, obtuse, turgid, 
pubescent; first glume one-fourth as long as the spikelet 
or less, usually obtuse; second glume and sterile lemma 
scarcely equaling the fruit at maturity; fruit 1.3 to 1.4 
mm, long, 0.8 mm. wide, elliptic, obtuse. 
Autumnal form usually stiffly spreading or radiate-pros- 
trate, internodes elongated, with tufts of short, appressed 
branches at the nodes; blades reduced, involute-pointed 
and often conspicuously ciliate at base, 
This common and widely distributed species is variable 
as to pubescence. Usually the plants are glabrous except the lower internodes and 
sheaths, but sometimes the pubescence extends nearly to the summit. ‘These more 
pubescent specimens, such as the type of P. funstont from California, Macown 26338 
from Ontario, Chase 3464 from Maryland, and Tracy 7947 from Texas, in the vernal 
form resemble less pubescent specimens of P. tennesseense but can be distinguished 
by the smaller spikelets. In the autumnal form the stiffly radiating culms with the 
tufts of short branches also distinguish this species.
