Gentiana polyantha, n. sp.—Glabrous annual, 3—6 dm. high, 
erect, consisting of a main axis and usually a pair of slender erect 
floriferous branches from each of the several-many nodes: leaves 
numerous, nearly all subtending cymose flower clusters; lower 
leaves oblanceolate, nearly sessile by a broadish base, 2-3 cm. 
long; middle stem leaves sessile, somewhat longer, from oblong 
to lanceolate; gradually passing into linear-lanceolate ones with 
broad base: the thyrsiform inflorescence often extending nearly 
to the base of the plant: calyx with 2 ovate-lanceolate foliaceous 
Sepals as long as the corolla tube, and 3 much smaller somewhat 
unequal nearly linear lobes: corolla blue or purplish; its tube 
10-13 mm. long; its ovate lobes about 5 mm. long, a broad lacerate- 
Setaceous scale fully half as long at the base of each.
