DIOFXIA— DIANDRIA. Salix. 181 



lialf the length of the lanceolate smooth germen and its smooth 

 shortish stalk. Style about the length of that stalk, with blunt 

 undivided stigmas. 

 The only matter of doubt regarding this Salix is whether it be 

 more than a variety of the Lapland .S. hastata. After culti- 

 vating them together for many years, I have always thought 

 them distinct. The hastata is more arborescent, with larger, 

 more heart-shaped, leaves, and very large stipulas, often above 

 an inch long, which give the leaves a hastate appearance. The 

 fertile cat/cins are likewise larger, and more woolly ; their scales 

 not so properly bearded, as clothed with copious dense wool. In 

 the germens, styles, &c., I find no difference. Dr. Wahlenberg 

 unites these two species, commending the plate in Ejigl. Bot. as 

 a good figure of his hastata, which, as he says, varies, " beyond 

 measure or belief," in the shape and dimensions of its leaves. 

 Thus far I might submit to his better opportunities of studying 

 the hastata, and all its possible varieties, wild, in Lapland. But 

 when the same learned writer reduces to this species S. Arbus- 

 cula, Linn. Lapp. n. 360. t. 8./. m, I cannot help suspecting a 

 great mistake, few plants being more distinct ; nor is 5. tenui- 

 folia of Afzelius, which we examined and named together, more 

 than distantly allied to either. W^ahlenberg's figure, t. 16./. 5, 

 does not answer to any of them, and cannot be meant for any 

 state of hastata or maUfolia. I have indeed S. hastata from 

 Switzerland, Haller's n. 16r>4, named .S'. Arbuscula long before 

 Wahlenberg's Fl. Lapp, appeared. A similar specimen could 

 hardly have misled him. It is difficult to conjecture what 

 .S'. hastata of M. Seringe, Sanies de la Suisse, b'^, can possibly 

 be, so inconsistent is the assemblage of synonyms, and so dis- 

 cordant is the description with our true Linnaean /ic/A^a/a. This 

 author never saw the leaves, without which notliing can be de- 

 termined ; but if once seen, they can never be mistaken. Three 

 species more dissimilar than my malifoHa, tenuifolia, and the 

 Linnoean Arbuscula, hereafter described, n. 33, cannot possibly 

 be brought together. 



l(j. ^. /jetioiaris. Dark-long-leaved Willow. 



Leaves lanceolate, serrated, sinootli ; fflaucoiis beneath ; 

 somewhat unccpial at the base. Stipulas lunate, toothed. 

 Catkins lax. Scales hairy, shorter than the stalks of the 

 ovate silky (^erinens. Stigmas divided, sessile.
