306 OBSERVATIONS ON WILLOWS. 



10. " Hsec forma S.pnrpurefE, in regionibus Europae septentrionalis 

 rarioi'j in Suecia vix adiuic visa. Iconi et descriptioni S. Forhyanep, 

 Sm., optime congmit." Obs. There is a resemblance in the form of 

 the leaves to S. Forbyana, but, notwithstanding, the plant is more 

 nearly allied to S. purpurea, \i., than to S. rubra, Huds. I believe 

 the S. Helix of Northern Germany has leaves naiTower towards the 

 base than this ; such is certainly the case in specimens from Professor 

 Koch. Mr. Ward: "No doubt of this being S. Helix of Eng. Bot." 



11. '^ S. purpurea, L." Obs. No doubt this is S. purpurea, L. 



12. 13. "A S. purpurea nuUo modo diversa." Obs. No doubt 

 these are forms of 8. purpurea, L., which it seems of little use any 

 longer to attempt to discriminate. Mr. Ward : " S. ramulosa, S. 

 Lambertiana, etc., are all forms of 8. purpurea, L." 



14. " 8. purpurea, forma latifolia." Obs. 8. Lambertiana = 8. pur- 

 purea, L., var. 



15, Ifi, 17, 18. No name or note by Dr. A. 

 19, 20. ''8. viminalis, L." 



21. " Mihi 8. stipularis, Sm., videtur." Obs. I hold this to be a 

 variety of 8. viminalis, a species which presents a considerable range 

 of forms. Mr. Ward : " Certainly a variety of 8. viminalis ; no ap- 

 pearance of stipules." 



22, 23, 24. No name or note by Dr. A. 



25, 26. " Hsec Salix forsan est 8. stipularis, Sm." Obs. Here I 

 am obliged to differ from Dr. A. My Essex Smithiana was admitted 

 by Mr. Borrer ,to be exactly Smith's plant. Mr. Ward : " Dr. An- 

 dersson does not appear to know our 8. stipularis. I think No. 26 the 

 true 8mithiana of Smith, and that 8. 8mithiana, Willd., is intermediate 

 between No. 31, 8. rur/osa or holosericea. Hook., — which this num- 

 ber, I think, truly represents, — and No. 26, the 8. 8mitMana, Sm." 



27, 28. "8. 8mitMana, Willd." Obs. I think Dr. A. is right here, 

 particularly as to No. 27. Mr. Ward: "No. 27, -S'. 8mitliiana, Willd. 

 No. 28, more 8. holosericea. Hook, than 8. 8miUiiana, Willd." 



29. "Optime 8. 8mithiana, Willd." Mr. Ward: "This may be 

 8. 8mithiana, Willd., as the leaves are not so silky as 8. 8mitliiana, 

 Sm." 



30, 31. " Mihi 8. acuminata, Sm. 8. lauceolata, Fries, videtur." 

 Obs. This does not at all resemble 8. acuminata, Sm. Eng. Bot., with 

 which Continental botanists do not appear to be acquainted. 8. acu-
