THE BRITISH WILLOWS 21 



brous, as they were in his S. lanceolata. Wimmer also relates 

 that he himself had confused them previously, but confesses his 

 mistake (Sal. Eur. p. 145), and declares the two plants to be 

 distinct. He makes the glabrous ovaries of 8. undulata the chief 

 distinction ; but the concolorous bracts not blackened at the tip, 

 and the sharply serrulate leaf-margin are equally good evidence 

 against this plant being derived from S. viminalis or being 

 identical with S. hij^pojjhaefolia. Dr. B. White adopted the views 

 of Andersson and others that S. undulata Ehrh. was one of the 

 forms of S. triandra x viminalis, which Andersson combined 

 under the name of S. multiformis Doell ; and his section headed 

 X S. undulata (I. c. pp. 355-359) calls for the caution that 

 Si undulata Ehrh. (S. lanceolata Sm.) is quite distinct from the 

 group of S. triandra x viminalis hybrids. 



S. undulata occurs from Surrey and Essex to Yorkshire, in 

 Koxburgh, Berwick and Perthshire, but being found in one sex 

 only is no doubt planted, being often propagated as an osier. 

 Europe Central from France to Eussia, and Scandinavia.

A tree with long branches spreading from a divided trunk, 

 recurving and drooping almost to the ground. Stipules narrowly 

 lanceolate, soon deciduous. Leaf-blades narrowly lanceolate 

 attenuate, finely dentate, glabrous, + glaucous beneath. Catkins 

 appearing with the leaves or soon after on leafy peduncles, 

 cylindric, slender ; bracts ovate-lanceolate, glabrescent ; ovaries 

 sessile ovate-conic, glabrous ; style very short. 



Planted as an ornamental tree ; allied to S. alba, with which 

 it hybridizes, but differing in its glabrous twigs, buds and leaves, 

 narrower catkins, and drooping habit. Native in Central Asia 

 from N. Persia to the Caucasus, it has been introduced for the 

 beauty of its pendulous branches into all parts of the world.]

A large bush or small tree, branches pubescent when young, 

 soon glabrous turning pruinose, at length reddish-brown shining. 

 Leaf-blades oblong or oblong-lanceolate, acute, subentire or ob- 

 scurely gland-serrate, glabrous or nearly so, ± glaucous beneath. 

 Catkins appearing before the leaves, sessile, densely silky, about 

 H in. long, $ \ in. broad, filaments adnate at the base ; $ about 

 \ in. broad, pedicels about equalling the shortly oblong nectaries ; 

 bracts oblong-obovate bluntly pointed, clothed with long silky 

 hairs ; ovaries ovate-conic glabrous, stigmas oblong entire, as long 

 as the long styles. Not indigenous ; recorded from Great Ayton, 

 Yorks, and found in some quantity by W. E. Linton, 1898, on a 

 bank by Chinley Station, Derbyshire, but since destroyed ; near
