376 SAL1CINEJE. [Salix. 



The following are slight varieties : — S. arena'ria, L. (partly) ; leaves downy 

 above woolly beneath, style equalling the capsule. — S. Stuartia'na, Sm. ; 

 leaves woolly above silky and cottony beneath, style equalling the cap- 

 sule. — S.glau'ca, Sm. (not L.) ; leaves snow-white and woolly beneath, style 

 much shorter than the capsule. (I should doubt this being the same 

 species.) 



13. S. Myrsini'tes, L. ; dwarf, leaves small rigid ovate obovate or 

 lanceolate glandular-serrate shining and reticulate on both surfaces, stipules 

 or lanceolate, catkins on leafy peduncles, scales spathulate blackish, 

 capsules hairy. S. retu'sa, Dickson (Andersson). 



Alpine rocks and rivulets in Mid. _Scotland ; alt. 1,000-2.700 ft. ; fl. June- 

 July. — A small rigid suberect or creeping shrub, young parts clothed with 

 silky deciduous hairs. Leaves usually £-1 in,, very variable, dark green 

 and glossy ; petiole very short ; stipules ovate-lanceolate, serrate. Catkins 

 ^-1 in., appearing with or after the leaves, on stout peduncles often as long, 

 oblong, male ovoid; scales pilose ; disk large; anthers at length black. 

 Capsule hairy or pubescent, distinctly pedicelled; style long, stigmas thick. 

 — Distrib. Alps of Scandinavia (Arctic), Mid. Europe, Siberia, N. America. 



The following are British varieties: S. procum'bens, Forbes (S. Ice'vis, Hook.) ; 

 leaves broad subacute faintly serrate.— Var. arbutifo'lia, Syme ; leaves 

 narrow acute or acuminate very faintly serrate. — Vaii. serra'ta, Syme ; 

 leaves ovate acute serrate. 



»$'. Graha'mi, Borr. MS. (Baker in Seem. Journ. Bot. 1867, 157, t. 66), is only 

 known from female specimens cultivated in the Edinburgh Bot. Garden, 

 said to have been brought by Prof. Graham from Frouvyn in Sutherland. It 

 appears to me to be a form of S. Myrsini'tes, with smaller catkins, paler scales, 

 and a perfectly glabrous capsule with a rather long very silky pedicel ; and 

 not allied to S. pola'ris or herba'cea. Syme suspects it to be a hybrid 

 between herbacea and nigricans or phylicifolia ; and Nyman, a sub-sp. of 

 S. retusa, L. The Engl. Bot. figures of the ovary and scale are very in- 

 correct. A similar plant occurs in Muckish Mt., Donegal. 



14. S. Sadle'ri, Syme; dwarf, leaves small short-petioled broadly ovate 

 or ovate-cordate subacute quite entire smooth and cottony above reticulated 

 and glabrous beneath, stipules 0, catkins terminating leafy branches, 

 scales oblong obtuse, capsule glabrous. 



liocky ledges of Glen Callater, alt. 2,500 ft. ; frt. Aug.— Prostrate branches 

 few, tortuous ; bark shining, red-brown ; shoots woolly. Leaves few, ^-1 in., 

 firm, dark green, young cottony beneath ; petiole § in. Catkins |-£ in., 

 cylindric, many-fid.; peduncle woolly, J-J in., leafless; scales woolly at 

 length dark brown, shorter than the capsules which are i in., glabrous, 

 conical-ovoid ; pedicels and persistent styles slender. — Only two plants 

 hitherto seen, both in ripe fruit. I am indebted to Dr. Balfour for the 

 loan of one here described. Nyman regards it as a sub-sp. of S. lana'ta, or 

 hybrid with this and reticulata. 



15. S. Arbus'cula, L. ; leaves ovate -lanceolate or obovate acuminate 

 serrulate shining above pale or glaucous beneath, catkins lateral on brao 

 teate peduncles, scales obtuss hirsute, capsules sessile tomentose.
