the capsules are not pubescent. The leaves are rather silvery 

 or light colored beneath. 



The silky willow, Sali.v sitchensis, is a very beautiful 

 shrub or tree on account of the leaves, which are very dark 

 green above and covered with silky pubescence beneath. Al- 

 though this species, in my estimation, is well worth knowing, 

 it is rarely noticed as it does not belong to the pussy-willow 

 type. It is more abundant along streams or rivers. The cat- 

 kins are long and slender. The staminate have one stamen to 

 a scale, the scales being light brown in color. The pistillate 

 aments have pubescent capsules. After the silky willow, Salix 

 Mackensiana begins to show its long pointed catkins, the bright 

 red anthers at the tip of the ament contrasting well with the 

 older yellow ones at the base. These flowers come out with 

 the bright green leaves. The scales are light brown, and the 

 capsules are smooth. Some of the leaves are cordate at the 

 base, and are often glaucus beneath. 



The gland willow, Salix lasiandra var. Lyallii is a very 

 gorgeous species, but in spite of this it blooms quite unnoticed 

 for most of the trees are leaved out and the other flowers are 

 abundant. The common name is given on account of the 

 glands where the petiole joins the blade. This species reaches 

 the height of a tree and is common about sloughs and situa- 

 tions where the water stands on the ground part of the year. 

 The tree is easily recognized from afar by the bark, which is 

 furrowed longitudinally. There are five or more stamens to a 

 scale, the scales being a light yellow in color. The capsules 

 are smooth. 



Nuttall, in his North American Silva, said of Salix 

 scssili folia : 



"This beautiful and very distinct species of willow formed 

 dense tufts on the rocky borders of the Oregon, at the con-
