546 MACKENZIE: NOTES ON CAREX 
strongly peduncled, few-several-flowered, the scales ovate or 
obovate, obtuse to acute, I-3-nerved, purplish brown with lighter 
midvein and conspicuous hyaline margins; pistillate spikes 2-5, 
usually 2—5-flowered, the upper one or two approximate or little 
separate, sessile or peduncled, the others widely separate, basal 
and strongly peduncled, the perigynia erect-ascending, the rachis 
zigzag; bract of upper spike green, scarcely sheathing, slightly 
purplish-tinged at base, normally exceeding inflorescence; scales 
ovate, acute to short-cuspidate, with several-nerved green center 
and hyaline margins and more or less strongly purplish-brown 
tinged, nearly as long and nearly as wide as, but not enveloping 
or concealing perigynia; perigynia sparingly puberulent, green, 
3-5-4.5 mm. long, the body short- to long-oval, 2.25-3 mm. long, 
1.75 mm. wide, 2-ribbed and otherwise nerveless or nearly so, 
triangular-suborbicular in cross-section, strongly stipitate (0.75-1 
mm.), abruptly contracted into the scarcely ciliate-serrulate, 
hyaline-tipped, obliquely cut, in age shallowly bidentate beak, 
0.75-1 mm. long; achenes triangular with strongly convex sides, 
closely enveloped by perigynia, 2-2.75 mm. long, nearly 1.75 mm. 
wide, truncate and slightly apiculate at apex, rounded at base; 
style slender, not enlarged at base, readily detached; stigmas three. 
The type specimen was collected by Mr. W. W. Eggleston 
(6605) southeast of Tierra Amarilla, Rio Arriba County, New 
Mexico, in the pifion belt at an altitude of 2,320 meters in the 
spring of 1911 (sheet 660821, United States National Herbarium). 
His numbers 6536, 6540, 6542 and 6610, collected in the same 
locality, also represent this species. Fendler’s 889 collected in 
New Mexico in 1847 (H) also belongs here. 
Carex geophila differs in the characters given in the key and in 
addition the. present species has narrower leaves, more slender 
staminate spikes, few-flowered pistillate spikes, strongly reddened 
culm bases and scarcely ciliate-serrulate perigynium beak. 
9. Carex geophila sp. nov. 
In large very dense clumps from tough, rather slender, much 
branched rootstocks, not stoloniferous, the culms from very 
, slender, very rough on 
the sharp angles; sterile culms strongly aphyllopodic. Leaves 
with well-developed blades 5-10 to a fertile culm, the blades 
flat with slightly revolute margins, 1.5-2.5 mm. wide, 2-15 cm.
