14:96 ARBORETUM AND FRUTICETUM. PART II F. 



Spec. Char., Sfc. Leaves broadly lanceolate, and pointed, with glandular ser- 

 ratures, smooth, glaucous beneath. Catkiny appearing before the leaves. 

 Ovary sessile, ovate, smooth. Style elongated. (^Sal. Woh., p. .51.) A 

 native of Switzerland and the south of France ; flowering at Wobiirn in 

 February, Introduced in 1820. It is a rapid-growing tree, with dark 

 afreyish branches, slightly covered with a |)owder, or bloom, similar to that 

 of S. acutifolia ; the branches ascending ol)li{jucly. The tree at Woi)urn, 

 though only four years planted, was, in 1830, nearly 25 ft. high. The 

 catkins appear often in February, from large crimson buds, which dis- 

 tinguish this species from every other, and make it very ornamental. 

 There are [)lants in the arboretum of Messrs. Loddiges, and at Flitwick, 

 and Ilenfield. 



Variation. The buds containing catkins are very large in the autumn; and, in 

 this state, it is the S. praj^cox gemmata Scr. Sal. twsicc. No. 83. (^Koch 

 Comm., p. 23.) 



5f 9. S. pomera'mca Willd. The Pomeranian Willow. 



Identification. Willd. Enum. Suppl., 6(). ; Forbos in Sal. Wob., No. 153. 



Synonymes. S. rfaphiioldcs J'iHars var., with narrower leaves, and more slender calkins. (Koch 

 Comm., p. 23.) Mr. Borrer, in his manuscript list of grouped species, has indicated it as l>cing 

 " probably a variety of S. rfaphnoides. 

 The Sexes. The female is described in Sal. Wob. 



Spec. Char., <^-c. Leaves lanceolate, tapering at both extremities, serrated ; 

 smooth and shining above, glaucous underneath. Stipules ovate, serrated ; 

 their margins generally revolute. Catkins about 1 in. long. Ovary 

 ovate, smooth. Style longer than the parted stigmas. {Sa/. JIW;., p. 281.) 

 A native of Pomerania. Introduced in 1822, and flowering, in the Woburn 

 salictum, in February and March. This is a rapid-growing kind, much re- 

 sembling, in the colour of its branches and its mode of growth, S. praeVox. 

 The branches are long, smooth, round, shining, and copiously covered with 

 small yellow dots : the preceding year's shoots are covered with a violet- 

 coloured [)owder, similar to that on the shoots of S. praiVox, and S. acutifolia. 

 The leaves are about i in. long, and nearly I in. broad, tapering towards 

 both extremities, serrated; the serratm'es somewhat glandular, smooth, and 

 shining on their upper surface, and glaucous underneath. Footstalks nearly 

 1 in. long, pur{)lish and villous on their upper side. Catkins appearing be- 

 fore the leaves, and about 1 in. long. There are |)lants in the Goldworth 

 Arboretum, at Woburn Abbey, Henfield, and Flitwick. 



Group iii. Triandra; Borrer. {.Sijn. y^inygdalinae Koch.) 

 Osier Willows, with three Stamens in a Flower. 



mmm 



Stamens 3. Leaves lanceolate, approaching to ovate, serrated, glabrous, 

 having large, rounded, toothed, more or less deciduous, stipules. Flowers 

 loosely disposed in the catkin. Pistil stalked. Ovary mostly glabrous. 

 Most of the kinds constitute excellent osiers, and become trees if left to 

 themselves. (Hook. Br. FL, 2d ed., with adaptation.) The kinds may be 

 denominated, generally, the osiers with 3 stamens in a flower. Most, or all, 

 when in the state of larger shrubs and trees, have their okler bark ex- 

 foli '.ted in broad patches, in the manner of that of the western ami eastern 

 plane trees (/^latanus occidentalis L., and P. orientalis L.). Most or all 

 are ornamental as shrubs, for their lanceolate, glossy, serrated leaves, and 

 their flowers.
