Elaeagnaceae. 



Shepherdia. Buffalo Berry. 

 (Family Elaeagnaceae). 



Shrubs or small trees, often 

 twig-spiny, with glistening fringed 

 silvery or red-brown peltate scales : 

 deciduous. Twigs nearly terete, 

 rather slender: pith small, round, 

 continuous. Buds rather small, 

 solitary or early multiple through 

 branching, stalked, oblong, with 2 

 valvate scales or a second pair 

 visible when these are parted. 

 Leaf-scars opposite, half-round, 

 minute, slightly raised: bundle- 

 trace 1: stipule-scars lacking. 

 (Lepargyraea). 



Winter-character reference to 

 Shepherdia argentea: Schnei- 

 der, f. 132. 



Shepherdia is confused with 

 Elaeagnus frequently, and her- 

 barium collections do not escape 

 this confusion entirely. Unlike 

 either Elaeagnus or Hippophiie, it has opposite leaves. Meyer, 

 in Linnaea, volume 7, p. 443, speaks of its buds being super- 

 posed, a condition resulting from branching, probably, if the 

 record does not rest on error. 



Scurf silvery. (1). S. argentea. 



Scurf red-brown. (2). S. canadensis. 



Winter-character references to Elaeagnus: E. angustifo- 

 lia. Bosemann, 49; Schneider, f. 132. E. argentea. Bosemann, 

 49. E. multiflora (E. longipes). Shirasawa, 235, pi. 2. E. um- 

 bellata. Shirasawa, 234, pi. 2.
