Parr 4, 1908] ROSACEAE 381 
Inflorescence cymlose, but by shortening of the branches the flowers are often conglomer- 
ate in small axillary or terminal clusters. Hypanthium campanulate or urceolate, at least 
in age contracted at the mouth. Sepals and bractlets 4, l-nerved. Petals none. Disk 
more or less developed, with the 2 stamens borne on the inner edge; filaments short, seldom 
more than half as long as the sepals: anthers extrorse, opening by a transverse slit. 
Pistils 1-8, usually more or less stipitate ; styles slender, basal; stigmas capitate.

Sarmentose-stoloniferous perennial, profusely rooting; stems and peduncles silky-stri- 
gose, the former 1-3 dm. high; basal leaves long-petioled; stipules brown, scarious, and 
entire; petioles 1-10 cm. long, strigose; blades reniform, 9-11-lobed, sparingly strigose 
above, sericeous and strongly veined beneath, 1-4 cm. in diameter; lobes rounded, deeply 
serrate; stem-leaves short-petioled or the uppermost sessile, with fewer lobes; stipules foli- 
aceous and more or less cleft; inflorescence cymose, but its branches often racemiform ;
