157t ARBORETUM AND IRUriCKTrM. PART III. 



when yoiinj;, afterwards glabrous, or nearly so, and shining, green, or tinged, 

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

 long. Leaves l)y no means remarkal)ly thin ; ovate or more or less rhomboid, 

 and having a short, dciiirved, somesvhat twisted |)()int ; on strong young 

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

 beneath ; sprinkled, when young, on l)oth surfaces with appresscd hairs, 

 some of which remain in the advanceil state; veins siuiken 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, pointeil, serrated, beset with glands on the edges and on the 

 lower j)art oi the disk. C!atkins appearing in May, before the ex[)ansion of 

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

 imbricated. Stamens thrice as long as the bractca. ' There are plants at 

 Woliurn, Henfickl, and Flitwick, and also in the (Joldworth Arboretum. 



'? I'arirti/. Mr. Borrcr states that he has, in his collection at llcnfield, from 

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

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

 is, perhaps, the plant mentioned in the F/nm liritannica, as deserving further 

 investigation, {liurnr in F'li^. Bot. Sii])j)l.)

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

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

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

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

 than the notched stigmas. (Borrcr in Fng. Bot. Suppl.) Finding in this 

 some apparently distinctive characters, we venture, after nuich 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 

 oi S. petnc'a, it has attained, in the same period, scarcely half the height of 

 that. {If)i(l.) S. petne'a is, in some instances, more than Ijft. high. There 

 are plants at Henfield, and in the Goldworth Arhoretiun.
