]net with having weak peduncles ascending after flowering and pro- 

 ducing few or no carpels, the other members of the group should be 

 looked for in the neighbourhood to account for then- parentage." 

 Such notes as these are very helpful, as coming from one whose 

 admirable si^ecimens, prepared bj " floating-out," are illustrations of 

 the process advocated. It may be noted here that the greater part 

 of Mr. Groves's herbarium was presented recently to the National 

 Herbarium, forming a welcome addition to the British Collection 

 there. 



The Rev. W. Moyle Rogers contributes among other notes, 

 a description of a new variety {Ritbus thyrsoideus Wimm. var. 

 viridescens Rogers MS.) from N. Devon and W. Cornwall — the 

 former collected as long ago as 1882 by himself and Mr. Archer 

 Briggs, "The closeness of the connexion with type seems to be 

 established especially by the combination of the strong deeply-furrowed 

 glabrous stem with the comparatively short curved prickles and 

 show}'" flowers of the panicle. It is, however, considerabl}'' unlike 

 in habit and coloration, besides having leaflets narrower and soon 

 bare beneath, vdt\\ panicle (when fully developed) considerably 

 branched and pm'plish petals. From B. rusticmius, towards which 

 it takes a step from type, it may be readily distinguished by its 

 epruinose stem, its more compressed prickles and longer stamens ; 

 and from my B. Sriggsicoius, which at first sight it recalls, by its 

 sulcate stem and short curved panicle-prickles, as Avell as by its 

 different leaves, greyer sepals and purplish petals." Of another of 

 his varieties {JR. mucronaUis Blox. var. nudicaulis) Mr. Rogers 

 writes : — "Though it is locally abundant in S.W. England, extending 

 northwards to Swallowcliff (S. Wilts) and eastwards to Marvel 

 Copse, near Newport (I. Wight), the distribution of this bramble 

 seems remarkably limited, and I have not found it in Sussex, Somerset, 

 Devon or Cornwall. Probably enough it occurs in all four counties. 

 In Dorset and S. Hants it is frequent and constant, to the apparent 

 exclusion of typical R. mucronaius Blox., from which it seems to 

 keep distinct," In his introductory notes Mr. George Goode, the 

 editor of the Report, thus refers to Mr. Rogers's withdrawal from the 

 post of referee : — ** The Rev. W. Moyle Rogers has for so many years 

 given us the benefit of his unique knowledge of the Biihi, in furnish- 

 ing us with criticisms on the specimens sent in, that members will 

 hear with the deepest regret that on account of increasing infirmity 

 he has at last felt compelled to resign his position of referee. We 

 are happy to say that the Rev. H. J. Riddelsdell, who has lately 

 assisted Mr. Rogers, has kindly promised to examine and — where 

 necessary — criticise all specimens of that difficult genus." 



A form of Rosa j)omiferay sent by the Rev. H. E. Fox, under the 

 name R. cinnamomeay from " Undercliff, Kingsdown, Kent, appa- 

 rently indigenous " is thus commented upon by Mr. W. Barclay : — 

 "This is not R. cinnamomea L. It is a variation of R. iwmifera 

 Herm., and as it has a certain number of subfoliar glands it might be 

 considered as R. pomifera Herm., f. recovdita Christ (Rosen der 

 Schwe?'z) = R. recondlfa Puget in Deseglise, Revis. sect. Toment. 46." 

 Mr. White has an interesting note on Pyrus Pyraster var.
