one generally on a stalk a fourth inch long, all of them fer- 
rugineous in color; bracts very short, only the lowermost 
prominent and that one little exceeding the pedicel of the 
spike; perigynium very small, trigonous and not inflated, 
smooth and nearly or wholly nerveless, contracted both ways, 
abruptly terminated in a short and entire beak; scale twice 
longer than the perigynium, lance-pointed, the margin dull 
brown and the mid-nerve broad and lighter colored.—Beaver 
Cafion, Idaho, Aug. 7, 1895. P. A. Rydberg (no. 2,339). 
/ 5. Carex Congdoni, n. sp.—Closest ally of C. Yosemitana 
Bailey (C. Sartwelliana Olney), from which it differs in the 
nearly or quite complete absence of pubescence on the leaves 
and sheaths, an androgynous terminal spike (pistillate at top), _ 
and especially in the shape of the perigynium, which is lance- 
olate and very gradually attenuated into the beak-like top, 
and slightly toothed. The perigynium of C. Yosemitana is 
ovoid, prominently widened above the middle and very 
abruptly contracted or rounded into a short and entire beak; 
that of C. Congdon is narrowly lanceolate or spindle-shape. 
I suspect that the terminal spike of C. Congdoni may be found 
to be sometimes wholly staminate. The Atlantic ally of 
these plants is C. vestita Willd.—California: Mt. Warren 
Pass, Tuolumne county, and east side of Mt. Warren, Mono 
county. J. W. Congdon, 1894. 
/ 6. Carex Arkansana, n. sp.—(C. rosea Schk., var.? Ar 
kansana Bailey, BoT. Gaz. 18: 87.) Sufficient material has 
now accumulated to show the true character of this plant, 
and it is clearly unlike C. rosea. It differs in its larger and 
glomerate spikes, the very broad and prominently spongy- 
based perigynium, and particularly by the two or three leafy 
bracts (from 1 to 5" long) which subtend the lower spikes. 
It differs also from Carex Muhlenbergii var. australis by i 
slender habit and long narrow leaves, by the long and leafy 
bracts, and especially by the spongy and broad-based pet! 
gynium. I have the plant from La Fourche creek, near Little 
nd 
from three places in Indian Territory: Muskogee, M. A 
v7. Carex Eggertii, n.sp.—An ally of Carex bullae” 
Schw., but more /upudina-like: coarser, with broad flat leave* 
spikes two to four and approximate, whitish, longer than in
