cannot be referred to that species. It would seem desirable to regard 

 jB. l^orreri and M. tomentella as synon^anous, as Crepin suggested 

 so long ago as 1896. 



li. EUBiGiNOSA L. Green records a few plants above the Eed 

 Noses, New Brighton. A specimen from a bush growing in a hedge 

 near Four Lanes End belongs to the BuhiginoscB, but as neither 

 flowers nor fruit were obtained it cannot be referred with certainty to 

 any named segregate. 



11. MiCRANTHA Sm. Recorded for Cheshire in List of British 

 Hoses. 



R. MOLLIS Sm. The type and var. ccerulea Woods are reported 

 as rare in Flora of Liverpool District. I have seen neither, nor are 

 they recorded for Cheshire by Woliey-Dod. 



K. TOMENTOSA Sm. This is described by Green as frequent. I 

 doubt very much the occurrence of real, typical tomentosa in the 

 Wirral district at least. Considerable attention was given to this 

 question, and no rose was discovered that could be referred with cer- 

 tainty to Smith's plant. Probably, much of what has been called 

 B. tomentosa Sm. is, in reality, B. oniissa Desegl., a species that has 

 been considerably misunderstood by some British Botanists. 



*R. OMISSA Desegl. Not infrequent, occurring chiefly on the 

 higher ground. *Var. sub moll is Ley by the footpath from Brim- 

 stage to Thornton. 



*R. SUBERECTA Ley. Near Irby, agreeing well with the author's 

 description, although Ley's own specimens seem to vary considerably. 

 *Var. glalrata Ley. Near Irbymill Hill. 



R. scABRiuscULA Sm. Recorded for v.c. 58 in List of British 

 Boses. 



R. JuNDZiLLiANA Baker. For an account of this plant, gathered 

 originally by Webb, near Moreton, reference should be made to 

 Baker's Beview of British Boses, p. 21, and to Wolley-Dod's paper. 

 The British Boses, p. 96. 



R. PiMPiNELLiroLTA L. Abundant on the sandhills at Wallasey. 



R. INVOLUTA Sm. sp. agg. Locally distributed. In considerable 

 quantity in a field west of Moreton ; in a hedge near the cross-roads 

 at Four Lanes End ; by the footpath between Brimstage and Raby. 

 The fruit is almost universally abortive. All my gatherings are 

 referable to B. Sahini Woods. From observations in the field and 

 from the characters of the hybrid itself, I am inclined to the view 

 that the second parent is always a form of B. omissa, which is the 

 commonest species of the Villosce section in the districts Avhere the 

 hybrid was noticed. Since B. i^impinellifolia is also common, there 

 seems to be no reason to question the indigeneity of the hybrid 

 as Green has done in ^'lora of Liverpool District. 



R. HiBERNiCA Tempi. Rare. The type, which has pubescent 

 leaflets, is reported to occur in the neighbourhood of Great Meols. 

 Yar. glahra Bak. A good colony on Irbymill Hill. It is, I think, 

 B. pimfinellifolia crossed with one of the glabrous forms of B. 

 canina. The leaflets ai-e rathei- narrow, slightl}^ acuminate, and quite 

 uniserrate. In 1917 only one fruit matured on the bush at Irbymill, 

 and on this the sepals ultimately became erect. It seems unlikely.
