almost of the same length: corolla about 15 mm. long, pur- 

 plish : fruit not seen. 



This species is evidently closely related to A. hypoglottis 

 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. Richardsonii and A. sfilcudens, 

 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).
