322 LAMSON-SCRIBNER: NOTES ON MUHLENBERGIA 
that of M. pauciflora, doubtless due to the condition of the speci- 
mens as noted above. ‘Culms densely caespitose, terete, erect, 
simple, rather rigid, about 1 ft. high. Leaves involute, filiform, 
about 7 to each culm, minutely scabrous outside, especially 
towards the tip, strigose scabrous within, 4-6 in. long, the lower 
ones shorter; ligules broader than the leaves, decurrent along the 
sheath, % line long, irregularly cut, continued on each side into 
two lanceolate, acute teeth or auricles one line long. Panicle slen- 
der, contracted, 2-3 in. long, rather densely flowered. Empty 
glumes nearly equal, 1—nerved, with slender acuminate points, I 
line long. Flowering glume nearly or quite smooth at the base, 
3-nerved, scabrous on the keel above, 114-2 lines long, terminat- 
ing in a slender awn 4-6 lines long. ~Palea nearly equaling its 
glume. 
‘Dry cliffs, Santa Rita Mountains, alt. 7,000 ft. Jinly.

There are two sheets of specimens in the National Herbarium, 
collected and labeled by Dr. Vasey himself, M. neo-mexicana, one 
from Watrous, New Mexico, 1884, and one from Las Vegas, New 
Mexico, collected in 1886. On both tickets there is written in 
Dr. Vasey’s hand “published in Bot. Gazette, Dec., 1886.”’ 
In the original description of M. neo-mexicana the type is not 
indicated. Probably several specimens were consulted in drawing 
up the diagnosis, for the range is given as “‘ New Mexico and 
Arizona,” and the culms are described as ‘‘mostly branched near 
the base from thickened nodes.’’ The Las Vegas specimens have 
simple culms while the Watrous specimen is branched as described 
by Vasey, and this specimen is assumed to be the type of his 
species. 
Among the numbered specimens in the National Herbarium 
referred to M. pauciflora Buckl. as here understood are the 
following: 
Texas: C. Wright 732, 1849. 
Cotorapo: Frank Tweedy 391, 1896. 
New Mexico: E. O. Wooton 1047, 1893; F. S. Earle 164, 1900 
(culms branched, panicles strict, 5-10 cm. long); E. W. D. Holway 
*The ‘no. 480” here cited was a private number for the collection made by 
Pringle in 1881 and is not the no. 480 of his distributed sets of 1884.
