Though the leaves are rather narrower and more crowded than is 

 usually the case, there seems to be no doubt but that the specimen 

 belongs to Salix viminalis. Mr. Druce thinks that another willow 

 in the same herbarium — the " Salix pumila angustifolia inferne 

 lanuginosa" (J. Bauhin) Ray Syn. 447. 2 — was also referred by 

 Smith to S. rosmarinifolia. In this case the plant is S. repens. 



As to the S. rosmarinifolia of Linne, salicologists differ in 

 opinion. Andersson considered that it was the above-mentioned 

 narrow-leaved and globose-catkined form of S. repens, and I am 

 inclined to agree with him. Wimmer, on the other hand, believed 

 it to be the hybrid between S. repens and S. viminalis (S. vimi- 

 nalis-repens, Lasch, S. Eriesiana, And.). Wimmer referred E. 

 B. t. 1365 (S. rosmarinifolia, u Linn.," Koch, Boswell-Syme) and 

 Sal. Woh. t. 87 {S. rosmarinifolia, Sm.) to S. viminalis-repens, 

 and by the evidence afforded by Leefe's specimens (Sal. Exs. i. 

 ^o. 19) mentioned above, Wimmer's identification seems to be 

 correct. The other plates, Eng. Bot. 1. 1366 and Sal. Woh. t. 86 

 (S. Arbuscula, Sm. not L.), appear to represent the form rosmarini- 

 folia of S. repens, as do Leefe's specimens No. 24, for which he 

 quotes Sal. Woh. t. 86. Boswell-Syme called Eng. Bot. t. 1366 

 "8. rosmarinifolia var. angustifolia, Wulf. ;" but Wulf en's S. an- 

 gustifolia is merely a synonym of the rosmarinifolia form of repens. 

 In Smith's herbarium the specimen labelled " S. Arbuscula, Fl. 

 Brit., Mr. Crowe's Garden, 1804," seems to be the same thing. 

 To which of the forms Dickson's plant " sent to Mr. Crowe " 

 belonged it is now impossible to say ; but I suspect that from 

 what Forbes, W. J. Hooker, Borrer, and Walker- Arnott say 

 regarding the close affinity of rosmarinifolia, Sm., and Arbuscula, 

 8m., it was probably a repens form. 



1 think that in the meantime neither S. repens f. rosmarinifolia 



nor & viminalis-repens can be admitted to a place in the British 

 Flora. 



In Linne's herbarium an example, labelled " 22 incubacea " by 

 Lmne himself, and, in an unknown hand, " Salix latifolia minor, 



B - 474," is a slender straight-branched repens with oblong 

 straight-pointed leaves moderately pubescent below. Some 

 authors have referred S. incubacea, L., to S. repens x aurita, and 

 °thers to S. repens X viminalis.
