MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 135 



men) not at all glandular, simple or branched above. Stipules ovate or ovate-lanceolate, 

 acute, often more or less toothed. Basal leaves 1-2 dm. long, pinnate ; leaflets 4-6 pairs, 

 often very densely villous but sometimes only a little hairy, obovate or cuneate, 

 toothed toward the apex, generally obtuse. Stem leaves similar but with fewer leaflets, 

 those subtending the subcapitate many-flowered cyme nearly equalling the flowers. 

 Hypanthium woolly-hirsute, cupulate ; bractlets linear, shorter than the lanceolate acute 

 sepals. Petals broadly spatulate, about 5 cm. long and 3 cm. wide. 



It is very nearly related to H. capitata and H. fusca, and slightly hairy specimens 

 are somewhat hard to distinguish from these species. It has about the same range as 

 H. parviflora. Specimens seen :

Stem erect, rather simple, 4-6 dm. high, nearly glabrous below, glandular-hirsute 

 above. Stipules broadly lanceolate, 2-3 cm. long, acuminate, more or less toothed. 

 Basal leaves 2-3 dm. long, pinnate, nearly glabrous ; leaflets 5-7 pairs, obovate or oval, 

 2-3 cm. long, deeply incised-toothed. Stern leaves similar, but the upper with narrower 

 oblanceolate acute leaflets, those subtending the subcapitate cyme simple, broad and 

 palmately divided into lanceolate, acuminate, glandular ciliate segments which about 

 equal the flowers. Hypanthium glandular-hirsute, deeply cup- shaped; bractlets linear, 

 nearly equalling the triangular-lanceolate acuminate sepals. Petals broadly cuneate, 

 5-6 mm. long and 4 mm. wide, much exceeding the sepals. 



H. capitata is very nearly related to H. fusca, and may be but a variety of that species. 

 There are no specimens in the collections I have seen that fully resemble Douglas' type 

 specimens; those collected by Cronkhite are the only ones that may be included in 

 H. capitata, but they are also so close to H. fusca that they may be referred to it. 



Oregon: Douglas; Cronkhite, 1864.
