MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 63 
Potentilla multisecta Rydb. Bull. Torr. Bot. Club, 28: 597. 1896. 
Innustrations: Pare 20, f. 6; dissection of flower, f. 7; stamen, f. 8; pistil, f. 9; 
fruiting hypanthium and calyx, f. 10. 
Stem erect, slender, 1-2 dm. high, more or less silky-strigose. Stipules ovate-lan- 
ceolate, acute, about 5 mm. long. Basal leaves with petioles 5-10 cm. long, more or less 
silky, digitate or pinnate with approximate leaflets; leaflets 8-7, the lower smaller, all 
dissected into linear or linear-oblong divisions. Stem leaves much reduced and_ few. 
Hypanthium silky, in fruit 5-7 mm. in diameter; bractlets and sepals oblong-lanceolate, 
acute, nearly equal. Petals obcordate, about one-half longer than the sepals. 
This was also included in P. dissecta by Watson. It is probable that this plant is the 
original P. dissecta Pursh, the description of which fits it, as well as P. Ranunculus 
Lange, better than the species for which the name is used, viz. P. diversifolia Lehm. From 
this, P. multisecta differs not only in the finely dissected leaves, but also in the smaller 
flowers. The leaves are not truly digitate, but the outer leaflets are attached a little 
lower, as in P. decurrens; all are divided into linear segments. ‘This species therefore 
connects the Aureae with the Multijugae, especially with P. pinnatisecta and P. muallefolia. 
It ranges from Nevada to British Columbia and Wyoming. 
Nevada: §. Watson (King’s Exp.), No. 330, 1868 (type); M. E. Jones, 1891. 
Wyoming: F. H. Burglehaus, 1898. 
Montana: F. W. Anderson, No. 125, 1885; Rydberg, No. 2691, 1895. 
British Columbia: Macoun, No. 7245, 1890 and 7246 (in part), 1891. 
§ 9. GRACILES. 
39. Potentilla subcoriacea. 
Stem from a thick perennial root, 8-5 dm. high, strigose and more or less glandular upward. 
Leaves dark green and shining, nearly glabrous, thick and somewhat coriaceous, digitate, with 5-7 
broadly obovate cuneate leaflets 8-5 em. long. Bractlets lanceolate, shorter than the sepals. Petals 
yellow, broadly obcordate, one-half longer than the sepals. 
This species most resembles P. ranuneuloides Humb. & Bonpl., from which it differs mainly in the 
size of the plant, the thicker and larger leaves and the glandular pubescence on the upper part of the 
stem. 
Mexico: C. G. Pringle, No. 5258, 1892. 
40. Potentilla etomentosa Rydb. 
Potentilla rigida Newberry, Pac. R. R. Rep. 6: Part 3,72. 1857. Not Wall. 1828.
