Salix 1 745 



B. Mature leaves ciliate in margin, covered more or less on both surfaces 



with appressed silky hairs. 



10. Salix alba, Linnaeus, Seep. 1759. 



Leaves 2 to 2\ in. long, f to 1 in. wide, covered with silky pubescence, 

 densest on the whitish under surface. A wide-spreading male or female tree, 

 with pendulous or spreading branchlets ; ovary and fruit sessile. 



11. Salix ccerulea, Smith, Seep. 1763. 



Leaves similar to those of S. alba, but thinner in texture, more translucent, 

 less pubescent, the lower surface being bluish grey and not white. A pyramidal 

 female tree, with ascending branches and erect terminal branchlets ; ovary and 

 fruit shortly pedicellate. 

 1 1 A. Salix vitellina, Linnaeus. See No. 6. 



Leaves occasionally ciliate till autumn, with both surfaces more or less 

 appressed-pubescent. This is readily distinguishable by the bright yellow 

 branchlets in winter, (A, H.)

 son, Monog. Salic. 75 (1863), and in De CandoUe, Prod. xvi. 2, p. 222 (1868); Willkomm,

 Mathieu, Flore Forestiire, 465 (1897); Camus, Monog. des Saules, 202 (1904). 



A small tree, occasionally attaining 40 ft. in height. Bark smooth and greenish 

 at first, ultimately ridged and fissured. Young branchlets, with a minute tomentum, 

 becoming more or less glabrescent in the second year. Buds ovoid-conic, minutely 

 tomentose or glabrous. Leaves oval or elliptic, about 2 to 3 in. long and i|- to if 

 in. broad ; apex acuminate, with the point usually directed to one side ; base broadly 

 cuneate, often unequal ; upper surface light green, slightly shining, glabrous except 

 for slight pubescence on the midrib and nerves ; lower surface bluish grey, reticulate, 

 covered with a whitish tomentum ; margin irregularly crenulate, undulate, or rarely 

 almost entire ; petiole more or less tomentose ; stipules oblique, reniform or half 

 cordate, dentate. 



Flowers appearing early, before the leaves ; catkins sub-sessile, with scale-like 

 leaves at the base, very silky, on account of the spatulate scales, brown or blackish 

 towards the apex, and pubescent with long hairs. Staminate flowers ; stamens two, 

 free, glabrous. Pistillate flowers ; ovary tomentose on a long pedicel, much surpass- 

 ing the gland in length ; style short, with two stigmas, which are usually emarginate 

 or rarely bifid. Capsules on long pedicels, narrow, elongated, covered with greyish 

 silky hairs. 



Varieties and Hybrids 



L S. Caprea is variable in the wild state. The catkins, which are usually sessile 

 or sub-sessile, are occasionally provided with leafy peduncles. The branchlets and
