ON SOME SCOTTISH RUBI. 47 



&c. M.P. Knock of Crieff; a form intermediate between type and 

 var. I have also seen dried specimens collected at Crianlaricli in 

 this vice-county, and at Dalmally in A., by the Eev. E. S. Marshall ; 

 at two localities in S. by Messrs. Kidston and Stirling; and on the 

 Island of Coll, M. Ebudes, by Mr. S. M. Macvicar ; and I think now 

 that a plant collected at Tongue, in W. Sutherland, by Mr. F. J. 

 Hanbury, which I formerly put to my R. moUissiimis, belongs more 

 probably to R. dmiicus. 



R. jyyranndalis Kalt. W.P. By L. Earn, a hairy form with long 

 narrow leaflets. M.P. .Near Killin ; the type. 



Egregii. 



R. mucronatus Blox. W.P. Frequent and locally abundant. 

 The type. Callander; about L. Venuachar and L. Earn ; Strathyre; 

 near Port of Monteith. 



E. MELANOXYLON Muell. & Wlrtg. W.P. Fairly common, and 

 seemingly distinct, in spite of considerable variation in armature. 

 Callander Crags ; near L. Vennachar and L. Earn ; moor between 

 Callander and Port of Monteith. From all these localities, except 

 the last, Dr. Focke has seen my specimens and thus named them, 

 adding, "The species is not well known, and its limits are quite 

 uncertain. Your plant from Scotland, however, is more like the 

 original specimens than anything I met with under this name." 

 A translation of Dr. Focke's brief description of this species (Koch's 

 St/ii. Fl. Germ. ed. 3) will be found in Journ. Rot. 1892, 268, and a 

 fuller account in Si/ii. R. G. 257, 258. It seems nearly allied to 

 Pi. mucronatus Blox. and R. podophyllus P. J. Muell., coming between 

 them and the more glandular states of R. calratus Blox., and dis- 

 tinguishable from the two former by its strong larger prickles, 

 more mixed armature, gradually acuminate leaflets, compound 

 panicle, and dark purplish-brown colour of stem and rachis ; and 

 from R. calvalus by the close even toothing and soft under surface 

 of its more roundish-acuminate terminal leaflet, as well as by the 

 mixed armature. The great range of variation in armature ob- 

 servable in the different bushes of this species is of course charac- 

 teristic of the group in which we find it ; but at times it is so 

 marked as to cause no little difficulty. I have no other British 

 specimens that quite match these Scottish ones ; but a plant that 

 the Rev. A. Ley finds at Moseley Mere, Herefordshire, may possibly 

 belong to the aggregate species. Of the Derbyshire plants that 

 have been thus named, Bloxam's from Dovedale is certainly typical 

 R. radala Weihe, and I agree with Messrs. Purchas and ^V. R. 

 Linton in thinking that the Shirley and Edlaston one is more 

 probably a glandular state of R. calvatiis Blox. Mr. Painter's 

 Staffordshire plant (Horton, and Lask Edge, Biddulph Moor), for 

 which Dr. Focke formerly suggested this name, looks (if I may 

 judge from rather indifferent specimens) as if it would go better to 

 R. podopliijllus P. J. Muell. ; while my very distinct Hants and 

 Dorset plant, described as R. melanoxylon by Prof. Babington in 

 Journ. L'of.-1890, 133, is R. melanodermis Focke. 



R. infestus Weihe. W.P. About Callander, in plenty ; by
