and S. densijlora, to the Siberian S. hctulifolia. Dr. l'^. L. Greene 

 apparently was the first one to point out that the Alaskan species 

 differed from all the other North American relatives in having 

 refiexed sepals. As this is a character found in the original ^. 

 bt'tulifolia he removed from that species all but the Alaskan plant. 

 The latter, however, differs considerably from Pallas's figure of 

 S. bctJilifolia, and also from Siberian specimens of the same in the 

 Torrey Herbarium. After some search among the literature on 

 the genus, I found that the Alaskan plant had been described by 

 C. K. Schneider. That ^^ Stevcni is distinct from .S". bctulifolia, is 

 evident. There may be some doubt, however, whether it is spe- 

 cifically distinct from S. BcauvenUana of which Schneider made it 

 a variety. I have seen no specimens of 5. Beauverdiana, but 

 from the characters given by Schneider, it seems distinct enough. 



It is strange that the oldest specific name and publication of 

 the beautiful little shrub of the mountains of California and Ore- 

 gon, usually known as S. arbusaila, should have been overlooked 

 so generally. Only in a single one of the later German works on 

 woody plants is the name mentioned ; and still, ^. splcndetis Bau- 

 mann was amply published. 



To 6". Hclleri, I refer, besides the type, the following specimens : 



California: Summit, Central Pacific Railroad, July, 1877, 

 H. Edivards. 



S.Japoiiica is occasionally found escaped from cultivation. I 

 have seen the following specimens : 



Pennsylvania: Point Pleasant, July 11, 1898, C. D. Fretz ; 

 Liberty, September i, 1906,/. K. Small. 



S. salicifolia is not found native on this continent. What has 

 gone under that name, is partly 5. latifolia, and partly S. alba. 

 The former is distinguished by its broad, obovate or oblanceolate 

 leaves and almost glabrous inflorescence. When the flowers first 

 open, they are usually more or less pinkish ; but in age they be- 

 come white. Even in " Gray's New Manual," 5. alba is described 

 as 5. salicifolia. The two resemble each other in the narrower 

 leaves and the pubescent inflorescence, but differ in the flowers, 

 which in 5. alba are white instead of deep pink, and in the leaves, 

 which are broader above instead of below or at the middle.
