1574 ARBORETUM AND FRUTICETUM. PART III. 



when young, afterwards glabrous, or nearly so, and shining, green, or tinged, 

 especially in the female, with brown. Petioles downy, spreading, rather 

 k>ng. Leaves by no means remarkably thin ; ovate or more or less rhomboid, 

 ami having a short, deeurved, somewhat twisted point; on strong young 

 shoots more oblong; dark green above and moderately shining ; glaucous 

 beneath ; sprinkled, when young, on both surfaces with appressed hairs, 

 some of which remain in the advanced state; veins sunken on the upper 

 surface, very prominent on the under one ; margin rather closely serrate, or 

 rather crenate, especially about the middle of the leaf, with a glandular 

 tooth in the notches. Stipules small, except on very vigorous shoots, half- 

 heart-shaped, pointed, serrated, beset with glands on the edges and on the 

 lower part of the disk. Catkins appearing in May, before the expansion of 

 the leaves; cylindrical, about 1 in. long when in full flower. Flowers closely 

 imbricated. Stamens thrice as long as the bractea." There are plants at 

 Woburn, Henfield, and Flitwick, and also in the Goldworth Arboretum. 



? Variety. Mr. Borrer states that he has, in his collection at Henfield, from 

 the same locality as the species, what seems a variety of it; having silky 

 hairs on the upper half of the ovary and towards the base of its stalk. This 

 is, perhaps, the plant mentioned in the Flora Britannica, as deserving further 

 investigation. (Borrer in Eng. Bot. Suppl.) 



* £ 121. S. propi'nqua Borr. The nearly related, or fiat-leaved, upright, 



Mountain Willow. 



Identification. Borr. in Eng. Bot. Suppl., t. 2729. ; Hook. Br. FI., ed. 3. 



The Sexes. The female is described in the Specific Character ,• and described and figured in Eng. 



Bot. Su]>pl. 

 Engraving. Eng. Bot. Suppl., t. 2729. 



Spec. Char., Src. Upright. Young shoots pubescent with minute down. 

 Leaves elliptical, obscurely crenate, nearly flat, nearly glabrous on both 

 surfaces; veins slightly sunken ; under surface pale green. Stipules small, 

 vaulted, glanded. Ovaries stalked, silky towards the point. Style longer 

 than trie notched stigmas. (Borrer in Eng. Bot. Suppl.) Finding in this 

 some apparently distinctive characters, we venture, after much hesitation, 

 to add another presumed species to a section of the genus, of which almost 

 every species is doubtful. It was discovered in Britain by Mr. Anderson, 

 and we know it only from plants received from him. Planted by the side 

 ( f S. petrae v a, it has attained, in the same period, scarcely half the height of 

 that. (Ibid.) S. petrae v a is, in some instances, more than 15 ft. high. There 

 are plants at Henfield, and in the Goldworth Arboretum. 



* 122. S. petr;e n a Anders. The Rock Sallow, or Willow. 



Identification. First distinguished by Mr. G. Anderson, who is understood to have given to it the 

 name of ,S'. petra^a. {Borrer in Eng. Bot. Suppl.) Forbes in Sal. Wob., No. 97. ; Borrer in Eng. 

 Hot. Suppl., t. 8725, ; Hook. Br. Ft, ed. 3. 



Synonymrs. S. arhuscula Wahlcnh., Koch Comm., p. 45., where Koch has remarked that he has thus 

 adjudged the .S'. petraTa Anderson from a specimen derived from Anderson. " It is surely by error 

 that Koch has placed S. p<tr;i'a under his ,S'. arbdscula, with <S'. phylicifolia Smith, and not under 

 hi* own .V. p\\\\u tifulia, with 8. AmmanniUna and its allies." {Borrer in Eng. Bot. Suppl.) If Koch 

 bad known the S. p<-tra:\i in the living plant, I believe that he would have referred it to his 

 own & phylicifolia. ! Borrer in a letter.)

 rated, carinate, twisted, reticulated with deeply sunken veins; beneath, hairy,

 having few glands. Ovary stalked, naked, wrinkled towards the point. Style 

 divided, Ifl MU than the < lovcn stigmas. S. pctra: v a is nearly allied to S.
