THE TRKn: WILLOWS OF ALASKA 283 



AmpIIfoUa resembles alaxcnsis in its size and robust growth, the 

 usually densely villous character of its twigs, its very large catkins, the 

 staniinate catkins of the two being scarcely distinguishable, its long 

 styles, and its slender stigma lobes. It has no real affinity with that 

 species, however, but its nearest relative along the Alaska coast is 

 possibly Salix barclayi Anders., a shrubby willow of abundant and 

 wide distribution in that region. At our camp on the west side 

 of Yakutat Bay, among the mouths of the streams that flow from 

 the glaciers of the St. Elias mountain range, a series of sand dunes 

 skirted the beach for a few miles and upon and near the dunes 

 grew this willow, associated with alaxensis. It was ordinarily 10 to 

 15 feet high, with a trunk 3 to 4 inches in diameter, but some trees 

 attained a height of 25 feet, with a trunk a foot thick. The numbers 

 collected here are 1122, 1123, 1153, and 1158. Mr. Kearney, working 

 meanwhile in Disenchantment Bay, a name applied to a portion of the 

 upper waters of Yakutat Bay, collected specimens at the Hubbard 

 Glacier (1061, 1062, 1074), ^^ -^SS Island (1013a), and on Haenke 

 Island (1089). At these localities, as on the sand dunes below, it 

 sometimes flowered and fruited as a shrub. Such specimens do not 

 show in all respects the full vigor and typical characters of the larger 

 plants, but they are believed to represent the species as influenced by 

 various adverse conditions, such for example as drifting sand and 

 shifting gravels. 



SALIX BEBBIANA Sargent. Bebb Willow. 



Salix roj/ra/« Richardson in Franklin, Journ. Pol. Sea. 753. 1823. Not 



Thuill. 1799. 

 Salix bebbiana Sargent, Gard. & For, 8 : 463. 1895. 



Type locality not given, but the description was based on specimens 

 collected on Sir John Franklin's first expedition, in the interior of 

 British America. 



This willow is widely distributed, extending almost entirely across 

 British America and occurring in most of the northern portions of the 

 United States, extending southward in the East to Pennsylvania, in the 

 Rocky Mountain region to New Mexico and Arizona, and on the 

 Northwest Coast to Oregon. The leaves in the Alaska specimens are 

 elliptical-lanceolate or ovate-lanceolate, either rounded or acute at the 

 base, acute or acuminate at the apex, sparingly pubescent when young, 

 becoming nearly smooth in age, usually crenate-denticulate, but some- 

 times entire, commonly 3 to 5 cm. long. Salix bebbiana was not ob- 

 served by the members of the Harriman Expedition, but three speci-
