is a most untrustworthy character ; Jepson calls it ' ' ovate ' ' ; Piper 

 "pyramidal," while Greene, when making determinations for Baker's 

 Sierran collections, referred to S. callicarpa forms with obviouslj^ 

 dome-shaped cymes. 



S. microhotrys Kydb. is described as being completely glabrous. 

 I have not seen Bessey's type from Pike's Peak, but have examined 

 a fairly representative series of the red-berried elder from the Colo- 

 rado-Montana region and believe that such an examination will lead 

 inevitably to the conclusion that in the Cordilleran section, S. race- 

 mosa shows every gradation from being conspicuously pubescent to 

 glabrate or even nearly glabrous.

1883. 



Type locality. — Not given, "first collected in New Mexico by 

 Fendler" (the only Samhucus collected by Fendler is his No. 286 from 

 "Margins of Santa Fe Creek.") 



Range. — Washington and Montana to California (east slope of 

 the Sierra) and New Mexico. 



Zone. — Canadian. 



Specimen examined. — Snow Valley, Ormsby County, Nevada, 

 2,460-2,615 m.. Baker 1155. 



This collection is the only one of the black-berried elder seen by 

 me from the Sierra. Bolmider 5052, from the Tuolumne region, 

 10,000 feet, lacks the fruit but was referred here by Dr. Gray because 

 of foliage character. R. A. Ware 2689c, from Lambert's Dome, 

 Yosemite, 9,100 feet, is perhaps to be referred here.

 rounded; leaves pubescent and thick 1. S. rotundifolius 



Corolla glabrous within; nutlets of the drupe obovate, cuneate, or conical at 

 base; leaves glabrate and thinner 2. S. oreophilus
