Tausch’s specimen is the only one of the above on which we have noticed hairy ovaries. 
Shrubs, growing to a height of about 3 — 5 m., smaller than x S', lanceolata. Young branches 
and buds glabrous at maturity. Petioles up to 1 cm. long. Laminae lanceolate to linear-lanceo- 
late, margin more or less undulate, denticulate, acute to acuminate, about 7^5 to io'o cm. long 
and up to i'5 cm. broad, glabrous at maturity, smaller and less gradually tapering than x S. 
lanceolata. Catkins subsessile or shortly peduncled, dense-flowered, much shorter than in x S', lanceo- 
lata, about 2^5 cm. long, not infrequently monoecious, appearing with or a little later than the 
leaves ; April and early May. Bracts ciliate or hairy. Stamens 2, sometimes 3. Ovaries usually 
hairy or glabrescent. Styles rather long. Stigmas more or less bifid. Capsules hairy or glabrous, 
stalked. 
The Rev. E. F. Linton (in Journ. Bot. xxxiv, 464, 1896) states that he has “succeeded in crossing S. triandra 
and .S. viminalis , and. .. 5 . hippophaefolia Thuiller. ..is the product.” 
The dense-flowered catkins and the long style of this hybrid suggest those characters as seen in .S', viminalis, whilst 
the leaves when full grown are intermediate in size and shape between .S', fragilis and .S', viminalis. The laminae vary a 
great deal with regard to the degree of glaucousness on the lower surface.

to Nottinghamshire.

Shrub. Bark flaking off in autumn as in S. triandra. Stipules usually persistent, acute to 
acuminate ; of the leaves of coppiced and summer-shoots large, acuminate. Petioles about 1 cm. 
long, decurrent at the base, glandular at the junction of the lamina. Laminae lanceolate, gradually 
narrowing to the apex, serrate, longer and narrower than in S', triandra or x S. undulata. 
Catkins on short leafy peduncles, appearing with the leaves ; mid-April to early May. Pistillate 
catkins long (up to 7 — 8 cm.), dense-flowered. Bracts covered with shaggy hairs, as long as the 
ovaries, variable in width. Ovaries rather broader than in S. triandra, stalked, glabrous, often 
abruptly constricted above the middle. Style rather long. Stigmas rather long and stout, more 
or less divided. Capsules usually glabrous, stalked; late May and June. 
This plant is referred by some authorities to alba x triandra. 
Smith (Eng. FI. iv, 169) insisted, and we think rightly insisted, that his S. lanceolata was a different plant from Ehrhart’s 
S. undulata (Ehrhart Beitr. vi, 101 (1791); Arb. 108!). Comparing the specimens of Smith and Ehrhart, we find that 
the laminae of Smith’s plant are, as in the illustration of the present work (plate 28), about 11 cm. long, whereas those 
of Ehrhart’s plant are only about two-thirds as long as this. Moreover, the laminae of Smith’s plant taper more gradually 
to the apex than those of Ehrhart’s. The petioles of Ehrhart’s plant are not glandular, thus differing from those of
