14-96 ARBORETUM AND FRUTICETUM. PART HI. 



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

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

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

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

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

 greyish branches, slightly covered with a powder, or bloom, similar to that 

 of S. acutifolia ; the branches ascending obliquely. The tree at Woburn, 

 though only four years planted, was, in 1830, nearly 25ft. 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 plants in the arboretum of Messrs. Loddiges, and at Flitwick, 

 and Henfield. 



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

 this state, it is the S. prae v cox gemmata Ser. Sal.~exsicc. t No. 83. (Koch 

 Comm.y p. 23.) 



9. S. POMERA'NICA Willd. The Pomeranian Willow. 



Identification. Willd. Enum. Suppl., 66. ; Forbes in Sal. Wob., No. 153. 



Synonymes. S. rfaphnoldes Villars var., with narrower leaves, and more slender catkins. (Koch 



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



probably a variety of S. daphno'ides. 

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



Spec. Char. y $c. Leaves lanceolate, tapering at both extremities, serrated j 

 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. (Sal. Wob., 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. prae x cox. 

 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 powder, similar to that on the shoots of S. prae^cox, and S. acutifolia. 

 The leaves are about 4 in. long, and nearly 1 in. broad, tapering towards 

 both extremities, serrated; the serratures somewhat glandular, smooth, and 

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

 1 in. long, purplish and villous on their upper side. Catkins appearing be- 

 fore the leaves, and about 1 in. long. There are plants in the Goldworth 

 Arboretum, at Woburn Abbey, Henfield, and Flitwick. 



Group iii. Tri&ndrfc Borrer. (Syn. y^mygdalinae Koch.} 



Osier Willows, with three Stamens in a Flower. 



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. y 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 older bark ex- 

 foliated in broad patches, in the manner of that of the western and eastern 

 plane trees (Platanus occidentalis L., and P. orientalis L.). Most or all 

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

 their flowers.
