MACKENZIE: NOTES ON CAREX 539 
blades inserted towards the base, the blades ascending, 1 mm. wide, 
usually less than 6 cm. long, roughened on the margins and towards 
the apex; leaves of sterile culms more numerous and with longer 
and somewhat wider blades; staminate spike solitary, erect, 
sessile, 2-4 mm. long, 0.5-I mm. wide, inconspicuous and often 
exceeded by the closely contiguous pistillate spikes, the scales 
ovate-lanceolate, closely appressed, acute, straw-colored with 
hyaline margins and tinged with reddish brown; pistillate spikes 
one or two, sessile or short-peduncled, approximate, suborbicular 
or short-oblong, 2-4 mm. long, 3 mm. wide, containing about 2-8 
ascending perigynia, normally with an additional, widely separated, 
basal spike; lower bract 5-10 mm. long, not sheathing and hardly 
colored at base; the upper much shorter; scales ovate, acute or 
short-acuminate, wider but shorter than the perigynia, tinged with 
reddish brown, the midrib green and the margins hyaline; peri- 
gynia puberulent, obovoid, obtusely triangular, nerveless or 
nearly so, the body 1.5 mm. long, I mm. wide, tapering to a 
stipitate base 1 mm. long, and abruptly contracted into a short 
(0.5 mm. long) beak with emarginate or shallowly bidentate orifice; 
achenes triangular (rather obtusely), short-oval, 1.5 mm. long; 
stigmas three 
The arstien forms of Carex varia Muhl. often resemble forms 
of Carex deflexa in which the basal spikes are not developed. 
They are, however, strongly cespitose and have squamiform bracts, 
which are normally hyaline-margined at base and do not usually 
exceed the culms.
