though it is descrihed as having a pubescent ovary, the original 

 specimens seen by him have glabrous ovaries ; and he suggests that 

 the hairs of the scales have been mistaken for ovarian pubescence. 



Wimmer thinks that under " undulata " several forms have been 

 mixed up ; whilst, to add to the confusion, Andersson himself, 

 though citing under Salix undulata, S. Trevirani, Spreng. and the 

 Sal. Wob. t. 13, repeats these citations under S. multiformis, to 

 which — in the sense in which he uses that name — they really 

 belong. 



As generally understood, however, undulata, Ehrh., differs 

 from lanceolata, Sm., only in having pubescent instead of gla- 

 brous ovaries, and is said to be extremely rare. From this 

 extreme rarity and from the doubt as to whether, the reputed 

 pubescent form was really otherwise identical with lanceolata, Sin., 

 I was inclined to consider the latter a hybrid, as Wimmer declares 

 it to be, of triandra and alba, very similar indeed to the triandra- 

 viminalis hybrids (multiformis, Doll, Anderss.), but distinguished 

 from these by the more distinct and stronger serration ot the 

 leaves, which in vernation are revolute and not convolute. 

 Against Wimmer' s theory the only point that militated was the 

 fact of the style of lanceolata being more distinct than in either 

 triandra or alba.

Messrs. Bailey and Painter. This has abnormal catkins, pro- 

 duced at the end of short branches in August. "Whether the 

 ovaries are similar to those of the spring flowers is yet uncertain ; 

 but they differ from those of ordinary lanceolata only in that 

 some of them are more or less pubescent. On the same catkin 

 occur ovaries almost or quite glabrous, some with a little pubes- 

 cence towards the top only, and others more generally pubescent, 

 and with the pedicel also pubescent. Whilst the occurrence of 

 these pubescent ovaries, taken in conjunction with the structure 

 of the style, seems to afford tolerably conclusive proof that un- 

 dulata is a hybrid of triandra with viminalis, it must yet be kept 

 in mind that, judging from what may be seen in other Salices, too 

 much reliance should not be put on the absence or presence of 

 pubescence. 



Taking, now, the forms which Andersson combines under mul- 

 tiformis, Doll, and Wimmer under S. triandra-viminalis, Wimm.,
