SALIX LUTEA platyphylla, n. var.—S. cordata var. Bebb in 
Kine, U.S. Geol. Explor. goth Parallel 5:325. 1871.—Shrub or 
small tree 3-6 m. tall; branchlets virgate or somewhat divaricate, 
yellow, shining, glabrous; buds yellow: stipules mostly small, 
semicordate to sublunate; petioles very slender, 8-15 mm. long, 
yellow, glabrous; blades differing from those of the species in 
being broader and shorter, elliptic-obovate, acute or short-acumin- 
ate at apex, broad and rounded or obliquely subcordate to cordate 
at base, 1.5-3 cm. wide, 4-8 cm. long, common sizes being 2 by 4, 
2-2.5 by 5, 2-2.5 by 6, and 2.5 by 7 cm., while sprout leaves reach 
such dimensions as 3.5 by 8,4.5 by 9, and 4-4.5 by 11 cm.: aments 
same as in the species except that capsules are longer stalked, 
pedicels ranging from 1 to 2.5 or sometimes 3 mm. in length. 
This variety occurs rather commonly in the Wasatch Mountain system 
from southwestern Utah to Idaho and ranges thence northwestward into 
Oregon. It is probable that it is more abundant than the specimens cited 
would indicate. It is separated from S. Jutea by the broad, ovate-lanceolate 
leaves and the more elongated pedicels, 1. 5—2 5 or 2mm. long. In flowering 
specimens, however, neither the broad leaves nor the elongated pedicels are 
certainly distinguishable. It is almost exactly the form described by BEBB a5 
“S. cordata var.” NutTatt describes S. lutea as having ovate-lanceolate
