BEPOET OF THE STATE BOTANIST. '71 



The broad glaucous leaves and drooping spikes on long fili- 

 form peduncles characterize this species. 



There is a late form (Forma serotina) in which the new growth 

 develops fruit soon after the old fruit has matured. In it the 

 s.aminate spike is inconspicuous or abortive, and the pistillate 

 spikes are erect and on peduncles much shorter than usual. 



Staminate spikes clavate; pistillate 2-5, erect, mostly on in- 

 cluded stalks; bracts about the length of their long sheaths or 

 obsolete ; perigynia acutely angled, finely nerved (obscurely in 

 80) with a short recurved or straight beak ; leaves radical, prom- 

 inently 3-ribbed (narrow and 1-veined in 80). 



Leaves narrow, l-veined pedunculata. 



Leaves Sribbed, bracts conspicuous 1 



Bracts obsolete, sheaths purple plantaginea. 



1 Leaves 2"-5" broad, dark green Careyana. 



1 Leaves 3''-12" broad, whitish-green platyphylia. 



77. Carex Careyana Torr. 



Stems l°-2° high, erect-spreading, smooth ; leaves rough be- 

 neath or smooth throughout, 2"-5" wide, shorter than the culm,

 i'-l' long, usually with a scale-like or slender green bract, scales 

 purplish or brown ; pistillate spikes 2-3, loosely 2-S fiowered, 

 the uppermost sessile at the base of the sterile, the others scat- 

 tered, sometimes the lowest remote on a partly included stalk 

 I'-iy long; bracts leafy, as long as their sheaths; perigynia 

 acutely triangular-ovate, 2"-2^" long, closely nerved, with an 

 oblique or recurved beak, twice the length of the ovate, acute or 

 mucronate purple-brown scale.
