1922] Wiegand,—Carex laxiflora and its Relatives 199 
15-50 mm. long, alternately flowered, loose, the rhachis smooth; scales 
oblong-obovate, broadly acute to subtruncate, mucronate or cuspidate, 
rarely muticous, whitish; perigynia 3.0-4.5 mm. long, broadly fusi- 
form, substipitate; apex short, slender, straight or slightly oblique, 
usually beak-like, whitish, subhyaline; nerves strong, 24—36.—Rich 
woods and banks in dry loamy soil: northwestern Nova Scotia and 
southern Maine to the District of Columbia and in the mountains 
to North Carolina and Tennessee, westward to Wisconsin and Illi- 
nois, also in Oregon. 
The broadest basal leaves are often absent at flowering time; 
hence much of the confusion in the synonomy of the older authors 
between their C. laxiflora and vars. plantaginea, patulifolia, and 
intermedia. The perigynia vary considerably in size and number of 
nerves, but the variations are gradual and varieties cannot be satis- 
factorily established.

C. laxiflora, var. Michauxii Bailey, Mem. Torr. Club l. c. as to the 
Michaux synonym at least.—Plants rather stiff and coarse, pale or 
glaucous; culms 0.8-1.8 mm. in diam., minutely granular-scabrous 
on the angles at least above; basal sheaths brown; broadest basal 
leaves 7-15 mm. wide; broadest cauline 2-7 mm. wide, all rather 
stiff; angles of the cauline sheaths smooth or slightly scabrous; bracts 
usually shorter than the culms; spikes scattered, the staminate pale, 
conspicuous, usually stout and clavate, usually peduncled; scales 
firm; anthers 3.2-4.3 mm. long; pistillate spikes (larger 15-35 mm. 
long) rather loosely and somewhat alternately flowered; rhachis, 
smooth; scales oblong, acute, cuspidate; perigynia 3.8-5.0 mm. long, 
broadly ellipsoidal, short-stipitate, more or less curved outward; 
apex evenly and gradually acute, firm; nerves 30-45.—Upland banks 
and woods: eastern Massachusetts to Alabama. 
The leaves differ in color and texture from those of C. anceps, and 
the perigynia contrast more in color with the scales, also they average 
larger. In distance between the flowers of the pistillate spikes this 
species lies between C. anceps and C. sfyloflexa. Two specimens 
have been examined which extend the previous known range from 
New Jersey to eastern Massachusetts. These are: Trumbull, 
Connecticut, 1908, E. H. Eames, no. 3934 (Herb. New Eng. Bot, 
Club), and Morse’s Pond, Wellesley, Massachusetts, 1910, K. M. 
Wiegand (in Herb. Wellesley College and New York State College 
of Agriculture).
