“ Anogra cinerea sp. nov. 
Branched perennial, stem 3-4 dm. high, whitish, cinereous, 
strigose when young ; leaves lanceolate to ovate-lanceolate, mostly 
subsessile, 3-5 cm. long, sinuate-dentate or denticulate, cinereous ; 
calyx glabrous or sparingly long-hairy, acuminate ; tips free and 
rather long; petals 15-18 mm. long; pods divergent at right 
angles to the stem, 3—3.5 cm. long, almost straight. 
This species is nearest related to “Anogra latifolia (Ocvothera 
pallida latifolia Rydb.), but differs in the almost glabrous not 
cinereous calyx and the narrower leaves.
