ovaries. {Hook. lir. FI., p. 417.) A native of Scotland, 



on the Clova Mountains, and also near Dumfries; growing 



to the height o( 1 ft., and flowering in April. Botanists 



are not agreed as to what is precisely the S, arbuscula //. 



Smith deemed it to be this; but Mr. Forbes (Sal. Wob., 



No. 86., and incidentally under No. 138.) and Mr. Borrer 



(Hook, Br. FI , ed. 2.) have concluded that it is not. Mr. 



Forbes was much inclined to regard it as not specifically 



distinct from S. rosmarinifolia Eng. FI. and Eng. Bot.; 



and Mr. Borrer, or Sir W.J. Hooker, or both, have regarded 



it as probably the same as the S. angustifolia Wulfen. As to its relation 



to S. rosmarinifolia, Sir W. J. Hooker says, " I agree with Mr. Borrer in 



thinking that they are distinct, though the difference lies almost entirely in 



their ovaries: these are shorter in S. angustifolia, with denser, less glossy, 



and less truly silky hairs, with ovate and quite entire stigmas, and more 



shaggy bracteas. There are plants at Woburn and Flitwick.

Spec. Char., $c. Leaves linear-lanceolate, nearly entire; dull green and silky

 downy. Ovary ovate, silky, nearly sessile. Style elongated. Stigmas 

 divided. (Sal. Wob., p. 175.) A native of? Switzerland. Introduced in 1823, 

 and flowering in May. A small shrub, with leafy downy branches, extending 

 obliquely from the ground to the height of 1 ft. or 1 ft. 6 in. The leaves are 

 from I,* in. to i in. long, or more; linear-lanceolate, entire, or nearly so, 

 some of them marked with a few glands about the middle; dull green and 

 silky above, beneath densely silky ; the young ones have somewhat a silvery 

 appearance underneath. Buds red before expansion. Catkins nearly 1 in. 

 long. A very distinct species, resembling in foliage the male plant of 

 S. rosmarinifolia.
