BEPOBT OF THE STATE BOTANIST. 71 



Tbe 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, 1-veiced pedunculata. 



Leaves 3-ribbed, bracts conspicuous 1 



Bracts obsolete, sheaths purple plantaginea. 



1 Leaves 2"-6" broad, dark green Careyana. 



1 Leaves 3*-12" broad, whitish-green platyphylla. 



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, 

 dark green ; staminate spike clavate, 5"-10" in length, its stalk 

 ^'-1' long, usually with a scale-like or slender green bract, scales 

 purplish or brown ; pistillate spikes 2-3, loosely 2-8 flowered, 

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

 tered, sometimes the lowest remote on a partly included stalk 

 I'-l^' 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. 



Woods and ravines. Eare. May. Cayuga, Genesee and 

 Jefferson counties. 



78. Carex platyphylla Carey. 

 Stems 8'-15' high, slender, erect, at length widely spreading, 

 smooth ; leaves shorter than the culm or rarely exceeding it,

 4"-lo" long, its peduncle i'-l' in length or rarely subsessile,
