LAMSON-SCRIBNER: NOTES ON MUHLENBERGIA 325 
culm and leaves, due doubtless to peculiarities of environment. 
The culms are 6-8 dm. long, leaves 10-18 cm. long, and panicles 
10-16 cm. long. In all essential characters they are identical 
with M. californica and we have no hesitation in uniting the 
species. 
MUHLENBERGIA LEMMONI Scribn. Contr. U.S. Nat. Herb. 1: 56. 
1890 
M. huachucana Vasey, Contr. U.S. Nat. Herb. 3: 69. 1892. 
Original description: ‘‘Culms much branched below, slender, 
erect or decumbent, 30-45 cm. high; leaves 2.5-7.5 cm. long, 2 
mm. wide, acuminate; panicle spikelike, 5-12.5 cm. long, inter- 
rupted below, the upper branches sessile, the lower pediceled and 
subdivided, sometimes 2.5-5 cm. long, erect; spikelets about 3 
mm. long without the awns; empty glumes ovate-lanceolate, 
awn-pointed, nearly equal and but little shorter than the flowering 
glume, which is hairy below and with an awn half as long as 
itself. Ballinger (Runnels Co., Tex.) (G. C. Nealley).’’ (Scribner 
Ee.) 
Type, G. C. Nealley 726, 1890, in National Herbarium. 
The sheet containing this specimen has also a ticket upon which 
‘Type No. 1079”’ is inscribed. 
The original description of M. huachucana is very similar to 
the above. It is as follows: ‘‘Culms tufted, much branched at 
the base, 12-18 in. high, leafy; leaves 4—6 in. long, 2 lin. wide, 
erect, rather rigid, scabrous; panicle 2-4 in. long, narrow, the 
lower branches sometimes in twos, all densely flowered, erect, 
contiguous; spikelets 2 lin. long, sessile; empty glumes about 
equal, 114-2 lin. long, ovate, acuminate-pointed, the long points 
scabrous; flowering glumes about 3 lin. long, 3-nerved, with a 
short awn; palet about as long as its glumes. Both flowering 
glume and palet villous-pubescent below. Huachuca Mountains, 
Arizona, J. G. Lemmon.” (Vasey.) 
The type of M. huachucana is not indicated by the author of 
that species, but thére are two specimens in the National Herba- 
rium so named by Dr. Vasey himself both of which were collected 
by J. G. Lemmon, one in July 1882, mo. 2915, Huachuca Mts., 
Arizona, the other in 1883, 20. 392, Arizona, without other data.
