(176 ) 
almost of the same length: corolla about 15 mm. long, pur- 
plish: fruit not seen. 
This species is evidently closely related to A. hypogilottis 
L., but distinguished by its long slender calyx-lobes. 
The type was collected by J. B. Tarleton at Five-finger 
Rapids, July 5, 1899 (no. 78).

Aragallus varians Rydb., n. sp. 
Cespitose perennial: leaves all basal, 1-2 dm. long, nu- 
merous: stipules lanceolate, scarious, long-acuminate, densely 
silky-villous, 1-2 cm. long: leaflets 30 or more, more or less 
verticillate, linear-oblong, silky-villous, obtuse, 1-2 cm. long, 
3-4 mm. wide: scape about 2 dm. high, slender, terete, spar- 
ingly villous: spike short, 4-5 cm. long, dense: bracts linear- 
lanceolate, long-attenuate, about 1 cm. long, exceeding the 
calyx: calyx tube often dark, cylindrical, about 5 mm. long, 
silky-villous: lobes linear-subulate, 2-3 mm. long: corolla 
about 1 cm. long, yellow: fruit not seen. 
Apparently related to A. Atichardsoniz and A. splendens, 
but easily distinguished by its yellow flowers and the fact that 
the leaflets are not always verticillate. 
The type was collected by J. B. Tarleton on Lewis River, 
June 28, 1899 (no. 33b).
