6. S. Piperi Bcl)l> in Gard. and Forest viii, 482 (1895). — Ball apud 

 Piper & Beattie, Fl, Xorthw. Coast, 116 (1915). — S. lasiolepis var. Bige- 

 lovii Auct., non Bcbb, ex parte. — This willow has been best described in 

 a field note sent to Bebb by Piper who collected it first. He said: " During 

 several seasons that I was especially interested in the collection of AVillows, 

 I found, near Seattle, only three plants, with one or two at other points. 

 Two of these, staminate, grew, one in a swamp near Lake Union, the other 

 not far distant in a Sphagnumbog on high ground. Both had several stems 

 rising from the same root eighteen to twenty feet high, not much branched 

 till near the top; branchlcts dark colored and smooth. The one pistillate 

 plant grew at the edge of Lake Washington, three miles from the staminate 

 mentioned above, in the old gravel beach of the lake. This, also, had sev- 

 eral stems three to four inches in diameter, with a smooth dark grayish bark, 

 sparingly branched; branches erect. Owing to its extreme isolation the 

 aments were imperfectly fertilized — perhaps by the pollen of Salix Scoul- 

 eriana, which grew in the vicinity and flowered at the same time." Bcbb 

 stated that S. Piperi is most nearly related to S. Hookeriana but differs " in 

 the entire absence of that grayish pubescence on both leaves and twigs so 

 characteristic of S. Hoolceriana. The leaves in one form are similar in out- 

 line, In others much narrower, with a very irregular repand margin. The 

 beautiful silkv aments are Hke those of S. Hoolceriana. The filaments.
