AMENTACE^. 475 



Leaves finely toothed. All the catkins on leafy stalks. Cap- 



siJes almost sessile 13. Whorile W. 



Catkins on short peduncles, at the last leaf of a branch, 

 with a bud in the angle. Stems prostrate or creeping. 



Leaves entire, wrinkled, white underneath 14. Heticulate W. 



Leaves finely toothed, not wrinkled, green on both sides . 15. Dwarf W. 



The well-known leeeping TV. (S. bahylonica, is of Asiatic origin. The 

 5. dapknoides, from continental Europe, with the male catkins like those of 

 the Sallow JF., but with lanceolate, pointed, green or glaucous leaves, is oc- 

 casionally planted, and has been seen apparently wild, near Cleveland in 

 Yorkshire; and some other Continental or North American species have 

 been described as British from planted specimens. Most, if not all, of the 

 British species are said to be also natives of North America. 



1. Bay VITillo^^. Salix pentandra, Linn. 



(Eng. Bot. t. 1805.) 



A slirub or small tree, from 6 to 20 feet high, glabrous or rarely shghtly 

 silky on the young shoots, the twigs green or yellow. Leaves broadly lan- 

 ceolate or oblong, pointed, finely toothed, thicker and moi-e smooth and 

 sliining than in any other species. Catkins cylindrical and loose, on short, 

 lateral, leafy shoots ; the males 1^ to 2 inches long, less hairy than in most 

 species. Stamens usually 5 but sometimes more, and there are almost 

 always 2 or even more entire or divided gland-lLke scales at their base. 

 Ovaries glabrous, nearly sessile or stalked. Capsules 2 to 3 lines long, of a 

 yellowish green. 



In damp, open woods, and along streams, chiefly in hiUy districts, ex- 

 tending all over Europe and Eussian Asia to the Arctic regions. In Bri- 

 tain, chiefly in northern England, southern Scotland, and Ireland. FL 

 spring, rather late. 



2. Crack ^MTillo^r. Salix fragilis, Linn. 



(Eng. Bot. t. 1807, S. Susseliana, t. 1808, S. deeipiens, t. 1937.) 



Yery near the common TV., but usually a more bushy though equally 

 large tree, and the foliage green and glabrous, or vei-y slightly sUky when 

 young; the catkins are rather longer and looser, the flowers larger, the cap- 

 sules more distmctly pedicellate and much more tapering at the top. 

 . Widely distributed, like the common IF., over Europe and Russian Asia, 

 and extensively cultivated, with nearly the same geographical limits. In 

 Britain, beheved to be indigenous in England, Ireland, and southern Scot- 

 land. Fl. spring. 



3. Common V^illo'w. Salix alba, Linn. 

 (Eng. Bot. t. 2430. S. ccerulea, t. 2431.) 



A tree of considerable height, the fohage of an ashy-grey or whitish 

 colour ; the young twigs green, purpUsh, or bright yellow. Leaves mostly 

 narrow-lanceolate, pointed and toothed, but not so finely as in the -Bay W., 

 and when young silky-white on both sides, or at least underneath, often 

 glabrous when old but never of a bright green. Catkins cylindrical and 

 loose, on short, lateral, leafy shoots. Stamens always 2, usually with 2 

 glandular scales. Capsule glabrous, sessile or nearly so, shortly tapering at 

 the top. 



In moist meadows, and hedgerows, in marshes, along streams, etc., 

 throughout Europe and Hussian Asia, except the extreme north, and exten-
