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 Hippophtie, 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.
