Salix Lapponum, L. Downy Willow. Catkins lateral, 

 thick, dense-flowered, sessile -or sub-sessile, white-tomen- 

 tose, appearing before or with the foliage; about 2 3 x 1 cm., 

 the ? on an evident stalk, with a few basal leaves. Gland 1, 

 linear-oblong, half as long as capsule. Scales spathulate, 

 distal moiety black, long, hairy on the back. Stamens 2, 

 free, glabrous; anthers yellow, passing to violet and brown. 

 Ovary sessile, white-woolly ; style long ; stigma divided. 



[Closely allied to this is the very rare northern species 

 S. lanata, L., the Woolly Willow, a dwarf and prostrate 

 Arctic species, with silky- woolly twigs and leaves. 



Catkins sessile or sub-sessile, two or three together at 

 the ends of the shoots, about 5 x 1/5 cm., densely silky and 

 with a golden shimmer. One gland only. Scales oblong- 

 lanceolate covered with long silky hairs, persistent; base 

 pale, apex dark. Stamens 2, free, glabrous. Ovary sessile, 

 glabrous ; style fairly long, divided ; stigmas bifid.] 



Jfjf Catkins not especially fragrant. Anthers 

 orange. Nectary of $ flower slightly 

 longer than the short pedicel. 



Salix Arbuscula, L. Bushy Willow. Small alpine 

 form with tufted twigs. 



Catkins small, appearing just after the foliage, with 

 minute basal leaves on the peduncle; about 1*5 3 

 x 0'5 1 cm. Scales rounded spathulate, short, yellowish 

 to rusty, velvety, ciliate. Stamens 2, free, glabrous, with 

 orange anthers. Ovary ovoid-conic, somewhat tornentose, 

 on a pedicel shorter than the gland. Style long ; stigmas 

 often breaking into filiform arms. 



Catkins large, usually at least 25 40 x 10 

 15 (20 80 x 6 25) mm.; arising from buds 

 down the sides of last year's twigs, therefore 

 lateral. Shrubs or trees of erect habit.
