rather before the leaves, usually becoming lateral from the development of only one of the 
buds near the extremity of the flowering branch: pedicels 4—6 lines long, villous. Invo- 
lucre nearly as long as the pedicels, very deciduous; the leaflets ovate, acute, yellowish, or 
tinged with purple. Teeth of the calyx minute, crowning the ovary. Petals lanceolate, or 
ovate-lanceolate, acuminate. Style filiform; stigma slightly dilated. Immature fruit twice as 
long as broad, somewhat hairy. This species, remarkable as the only one of the section 
Tanycrania found in America, is closely allied to C. mas of Europe and C. officinalis of Japan, 
differing only, so far as our imperfect materials show, in the slight characters given above. Dr. 
Bigelow’s specimens have the foliage and the young fruit. A branchlet gathered by Mr. Prat- 
ten exhibits the flowers just developing.

sides, Duffield’s Ranch, Sierra Nevada; May 12; with unexpanded flowers. We incline to 
the opinion that this species is more siearly allied to C. alba (stolonifera) than to C. sericea, 
It varies in the degree of pubescence and in the breadth of the leaves,
