96 EKPOET OF THE STATE BOTANIST. 



inate spike linear or sub-clavate, 1' long, often inconspicuous, 

 sessile or shortpeduncled ; pistillate spikes 1-3, usually 2, densely 

 flowered, globular, contiguous or subdistant tbe uppermost ses- 

 sile, the lower shortpeduncled, erect, fi'-Q" thick ; bracts leafy, 

 longer than the culm ; perigynia turgid-ovate or ovoid, 25-30 

 nerved, G"-9 " long, smooth, widely spreading and deflexed, taper- 

 ing into a long bidentate_ beak, about twice the length of the 

 broadly ovate, acute scale. 



Wet places in the central and western part of the State, rare 

 in the eastern part. July. 



The large yellowish-green spikes, mostly contiguous and of a 

 bur-like aspect, sufficiently mark this tine species. It is related 

 to the next following species to which it has sometimes been sub- 

 joined as a variety. It is C. AsaGrayi Bailey. 



Var. hispidula G-ray. Perigynia hispidly -pubescent. Greene 

 county. 



118 Carex intumescens Rmlge. 



Stems 15-30' high, slender, erect, acutely angled, smooth be- 

 low the middle, sometimes with a few short stolons ; leaves 

 l^"-3" broad, rough, longer than the culm, dark green ; staminate 

 spike cylindrical, |'-2' in length, subsessile or on a stalk i'-iy 

 long ; pistillate spikes 1-3, 5-10 loosely or subdensely flowered 

 (rarely 1-3 flowered), globular, contiguous or approximate, ses- 

 sile or the lowest on a short stalk 3"-6" in length, dark green, 

 often becoming blackish in drying; bracts leafy, sheathless, 

 much surpassing the culm ; perigynia turgid-ovoid, 15-20 nerved, 

 widely spreading, tapering into a long, smooth or roughish bi- 

 dentate beak, about twice longer thau the oblong-ovate cuspi- 

 date scale. 



Wet places in fields or woods. Very common. June, July. 



This species has more slender culms, darker foliage, fewer 

 flowered spikes and fewer nerved perigynia than C. Grayii, to 

 which it is closely related. It is quite variable. In shaded 

 places there is a very slender form with one to three perigynia 

 in a spike; also in open places there is a very slender form with 

 two to three scattered spikes having one to five rather small 

 perigynia in each. These sometimes assume a reddish-brown 

 polor even before maturity.
