1. Sratice labradorica (Wallr.) Hubbard & Blake, comb. nov. 
Root long, slenderly tapering, white within. Scapes 1-7, glabrous 
or densely shortly spreading-pubescent, 2.8-27 cm. high. Leaves 
in a dense basal tuft, narrowly linear, shortly subulate-pointed or 
slightly apiculate, glabrous or rarely ciliate, 1-nerved or the broader 
3-nerved, the nerves slightly impressed above, 3.5-8 cm. long, 0.7- 
1.5 (-2) mm. wide. Heads hemispheric, 1.5-2.1 em. in diameter. 
Two outermost bracts lance-ovate, acuminate, scarcely mucronate, 
glabrous, with brownish center, about 8 mm. long; next three empty, 
broadly elliptic, mucronate by the excurrent brown midrib at the 
rounded apex, 8 mm. long, 5 mm. wide. Spikelets 2-3-flowered. 
Fruiting bract suborbicular-cuneate or -obovate, broadly rounded at 
the somewhat undulate apex, scarious-membranaceous, very slightly 
greenish-nerved in middle, with brownish center and often purplish 
border, 7.5-8.5 mm. long. Pedicels glabrous, short; scar of attach- 
ment oblique, ovate. Calyx obconic below, with funnelform limb, 
6-7 mm. long; proper tube 3-3.3 mm. long, 10-ribbed, densely 
ascending-pilose on all the ribs as well as on the cross-ribs (i. e. those 
connecting the main and intermediate ribs), and more or less densely 
ascending-pilose between them, at least toward the summit of the 
proper tube; limb 5-lobed, whitish to pale lavender, scarious, the 
5 brown or purplish-brown short-pilose nerves evanescent in the middle 
of the lobes or running to their apices and prolonged into a cusp; 
lobes deltoid or lance-deltoid, from acuminate to apiculate, short- 
cuspidate, or long-cuspidate, about 1.2 mm. long; intermediate teeth 
truncate, emarginate, or rounded, about 0.3 mm. high. Petals lilac.
