324 LAMSON-SCRIBNER: NOTES ON MUHLENBERGIA 
treated, although no. 1028 represents the usual form as shown by 
more recently collected material, for example nos. 2113 and 2116, 
collected by S. B. Parish in 1890, both from the region of the 
San Bernardino Mountains. 
The following is a description of the species M. Parishii as 
here understood: 
An erect, rigid, rather stout glabrous perennial 4—6 dm. high, 
from creeping woody rootstocks, with many-jointed culms, fas- 
ciculate-branched at the base, flat, scabrous leaves, densely 
flowered contracted panicles, and scabrous spikelets 3-4 mm. 
long. Culms minutely scabropubescent for a short distance 
below the nodes; nodes usually seven; sheaths mostly longer than 
the internodes, terete or slightly compressed, scabrous; ligule 
about I mm. long, lacerate and subciliate on the margins; leaf 
blades usually erect or ascending, rather rigid, very acute, 3-12 
(usually 5-7) cm. long, 3-8 (usually about 5) mm. wide, the mar- 
gins more or less revolute in drying; panicles 6-12 cm. long, 
lanceolate or linear in outline, more or less interrupted below; 
branches of the panicle erect or appressed, solitary or the lower 
in pairs, densely flowered to the base, or the longer lower branches 
naked below; spikelets broadly lanceolate, somewhat compressed, 
crowded and more or less glomerate, sessile or on very short 
pubescent pedicels; glumes broadly lanceolate, acute, acuminate, or 
pointed with a short awn, rather firm in texture, scabrous, strongly 
so on the prominent midnerve excepting near the base, nearly 
equal, as long as or a little shorter than the lemmas; lemmas 
broadly lanceolate, 3-4 mm. long, scabrous, copiously hairy near 
the base with hairs about 1 mm. long, awned or nearly awnless; 
awn when manifest rarely exceeding 2 mm. in length; palea 
broadly lanceolate or oblong, acute or minutely 2-toothed at the 
apex, hairy near the base and similar in texture to the lemma. 
The hairs at the base of the lemmas and paleas vary in length 
and in abundance but are always conspicuous. 
Allied to M. Lemmoni Scribn. but differing in the stouter 
culms, broader leaves, and larger and more scabrous spikelets. 
No. 1076, Parish Brothers, from the San Bernardino Mountains 
of Southern California, collected in July, 1881, and now in the 
National Herbarium, is assumed to be the type. A second, and 
the only other specimen in the National Herbarium, was collected 
in 1882 by the Parish Brothers and distributed under the same 
number (1076). They both represent luxuriant forms of Vasey’s 
M. californica, differing only in a more rank development of the
