MACKENZIE: NOTES ON CAREX 435 
the plant now under discussion. In the absence of opportunity 
to examine the original specimen, I am not changing the applica- 
tion of the name. Tuckerman’s Carex neglecta (Enum. Method. 
19) is the oldest specific name for the species, but the name 
“neglecta” had previously been used by other authors for other 
species. It is interesting to note that both Tuckerman and 
Wahlenberg (if his name is correctly applied) erroneously placed 
this species among those with the staminate flowers below the 
pistillate. 
The best characters to separate the three species in question 
may be contrasted as follows: 
Stig gm ] 1 ot twisted, elongated light ish | 
tabeing or but robes contracted into beak, inccimolcusunly. whibe! 
hyaline at the o 
Stigmas stouter, i short, deep brownish red; perigynium con- 
tracted into beak, conspicuously white-hyaline at the orifice. 
Leaf-blades averaging 2.5 mm. wide; spikes usually with nine to 
twelve perigynia; perigynia 3.25—-4.5 mm. long, widely radiating. C. convoluta. 
Leaf-blades ps little more than 1 mm. wide; spikes usu 
with two to six perigynia; perigynia 2.5-3 mm. long, more 
ascending.

237. 1805; Riedgr. Nachtr. 15. pl. 222, f. 179. 1806

Carex rosea var. staminata Peck; E. C. Howe, Rep. New York 
State Mus. Nat. Hist. 48: 132. 1895. 
Densely cespitose, the culms 2-5 dm. high, slender, 1-1.75 
mm. wide at base, aphyllopodic, smooth or slightly serrulate on 
the angles above, usually exceeding but at times equalled by 
leaves, light brownish tinged and fibrillose at base. Leaves vith 
well-developed blades three to six (usually four or five) to a culm, 
on lower fourth, but not bunched, the blades erect-ascending, 
I-2 mm. wide, 3 dm. long or less, light green, flat, strongly minutely 
serrulate on the margins and on the veins towards the apex, the 
sheaths tight, not septate-nodulose. Spikes four to eight, andro- 
gynous, in an elongate terminal head, 5 cm. long or less, 5~8 mm. 
wide, the lower three to five separate, the upper three or four 
aggregated. Staminate flowers apical, inconspicuous, with the 
four to twelve ascending or at maturity widely radiating perigynia 
below. Bracts bristle-form, that of the lowest spike conspicuous, 
10 cm. long or less, those of the upper spikes much smaller and 
often rudimentary. Scales triangular-ovate, greenish hyaline, 
C, rosea. 
C. radiata.
