RowLEE: Two NEW WILLOWS 159 
becoming more lax as the capsules mature ; scale membranous 
and green at first, becoming tawny, with 3 or 4 prominent par- 
allel veins, oblong, more than twice the length of the pedicel, 
rounded at the apex, crisp-hairy on the back; capsule large, 
prominently rostrate, clothed with short spreading silky hairs, 
about 8 mm. long at maturity, pedicel short (1 mm.), about twice 
the length of the yellow gland; style glabrous, 1 mm. long, sur- 
mounted by four stout stigmas ; style and stigmas reddish-brown ; 
stamens 2, filaments with a few spreading hairs at the base. 
This beautiful shrub is obviously related to Salix glaucops 
Anders., but differs in having glabrous serrate leaves. Its leaves 
and buds suggest S. /ucida.
