122 ANNALS OF SCOTTISH NATURAL HISTORY 



Ranunculus petiolaris. I recently learned from Mr. Arthur 

 Bennett that this name is preoccupied ; it was used by Boupland, 

 Humboldt, and Kunth in their " Nova Genera et Species Plantarum," 

 vol. v. p. 45 (1821), when describing a Mexican buttercup, which 

 their figure (No. 428) shows to be a totally different plant from 

 mine. The West Highland Ranunculus published some years 

 since under this title may bear the name of R. scoticus for those 

 who, like myself, believe it to be specifically (or subspecifically) 

 distinct ; if it is regarded as a variety, I suppose that it can stand 

 as R. Flammula, L., var. petiolaris^ Lange, according to my 

 original description. EDWARD S. MARSHALL. 



Plants of West Ross. * Hieracium argenteum, Fries, occurred 

 on the Cnochan Cliffs in 1892. Accidentally omitted from my 

 list in "Trans. Bot. Soc. Edin.," 1894, p. 148. 



* Carex limosa, L. Near Gairloch. 



Asplenium marinum, L. Isle of Longa. T. B. Cartwright, in 

 Herb. Oxon. G. CLARIDGE DRUCE. 



Rosa dumetorum, Thuill. I found this Rose about Brodie, 

 Nairn, in 1896, and Rosa coriifolia, Fries, about Elgin. M. Crepin 

 has named both of these. G. CLARIDGE DRUCE. 



Poa eenisia, All., var. flexuosa ( Wahl.\ a new species of Grass 

 in Scotland. Last August, during my search for Carex helvola, I 

 found a Poa in small quantity on the south-west cliffs of Ben 

 Lawers, which was new to me. Professor Hackel writes to me, in a 

 letter received this day (i4th March), that it is identical with 

 specimens from the Dovrefield of Poa flexuosa, Wahl. the Poa 

 arctica, Brown, which is put by Nyman as a sub-species of Poa 

 ceirisia of Allioni. It has not been previously recorded for Great 

 Britain. G. CLARIDGE DRUCE. 



Set of British Willows issued by Rev. Edward F. Linton, 

 M.A., F.L.S., and Rev. William R. Linton, M.A., F.L.S. The 

 fourth fascicle, issued in February 1898, contains 37, instead of 25, 

 numbers. Like the earlier fascicles, it is noteworthy for the care 

 with which it has been prepared and for the excellence of the pre- 

 parations. 32 forms are illustrated, of which 27 are hybrids. Of 

 the latter, several have been artificially produced in cultivation. 

 They represent crosses that might occur in nature from the associa- 

 tion of the parent species. A number of the specimens in this 

 fascicle are from localities in Scotland, or have been taken from 

 plants brought from Scotland and cultivated. Scottish botanists 

 will find this collection of Willows a valuable aid in working out 

 local forms of a difficult genus. 



British Sedges. In a paper on British species of Carex in the 

 Journal of Botany (1898, pp. 73-82), the Rev. E. S. Marshall notes 

 the following from Scotland :
