(not ‘‘northwestern,” as SCHNEIDER states). The specimens so determined 
by him are listed later. Two chief districts are involved. The localities in 
00 
miles to the southeast, forming part of the watershed between the Rio Grande 
and the Pecos rivers. I am by no means convinced that all of this material 
represents S. Gooddingii instead of a form of S. nigra.

SALIX LAEVIGATA araquipa (Jepson), n. var.—S. laevigata forma 
araquipa Jepson, Fl. Calif. 339, 1909.—The original description by 
Jepson reads as follows: 
Forma araguipa Jepson, n. form. Small tree; one-year-old shoot with 
dense close tomentum; brown tuft of hairs on old wood at base of season’s 
shoot very conspicuous; leaves reddish brown above; catkins long and dense. 
Arbor parva ramulis annotinis cum denso appresso tomento; valde manifestus 
caespes fusci pili basi horni ramuli in ligno vetere; folia rufo-fusca supra; 
amenta longa artaque.—Dry gulches, Araquipa Hills, Solano County, May 2-6, 
1891, W. L. J 
The type came from “dry gulches, Araquipa Hills, Solano 
County (California), May 2-6, 1891, W. L. Jepson.’ This county 
lies northeast of San Francisco. I have not seen the type specimen, 
but an examination of the material in the National Herbarium, as 
well as that in my own herbarium, shows that this variety is found 
rather rarely in central California, but occurs commonly in the 
southern part of the state, comprised in Los Angeles, Orange, 
Riverside, San Bernardino, and San Diego counties. The vesture 
of the seasonal twigs, the buds, the petioles, and even the basal 
portion of the midrib, especially beneath, makes such a striking 
contrast with the glabrous and shining epidermis of the typical 
form that forma araguipa seems worthy of varietal rank. It 
should be noted, however, that the conspicuous tuft of brown hairs
