ovate, cuspidate, sparsely glandular-ciliate: lower stem-leaves similar

above: heads pedunculate, many-flowered, peduncles more or less 
bracteolate: involucre broadly campanulate, about 1.5 cm. broad: 
bracts indistinctly 2-seriate, herbaceous, the inner obovate, subacute, 
margin spinulosely denticulate scarious toward the base about 9 mm. 
long, outer bracts narrower, about 7 mm. long, rarely denticulate, all 
slightly glandular-hispidulous: corollas white, radiate about 12 mm. 
long, tube about 4 mm. long, outer lip oblong, about 8 mm. long, 3 mm.

CAREX PAUPERCULA Michx., var. brevisquama, n. var., squamis 
3-4 mm. longis perigynium subaequantibus. 
Scales 3—4 mm. long, about equalling the perigynium.— QUEBEC: 
Tle-aux-Coudres, Charlevoix Co., June, 1917, Bro. M.-Victorin, no. 
4021 (TYPE in Gray Herbarium). 
Remarkable in its very short scales which give the plants a distinc- 
tive aspect, the long-acuminate scales of typical C. paupercula being 
5-8 mm. in length and much exceeding the perigynia.— M. L. FERNALD, 
Gray Herbarium.
