 Low bushes on a mountain side, above Llys-y-wynt, near Llanfair- 

 fechan ; alt. about 600 ft., 25th September, 1884. "Avery striking 

 plant, with prickles very unlike those of tomentosa ; it seems to con- 

 nect this with Borreri or Bakeri." — T. R. Archer Briggs in litt. — 

 Charles Bailey. Prof. Crepin writes concerning this: "Very 

 curious, on account of the form of its prickles. It remains to be 

 seen whether we have to deal with an individual plant, or whether 

 there are several bushes. [Mr. Bailey's ticket says low hushes, so 

 this part of Prof. Crepin's note is answered.] Mr. Bailey would do 

 well to gather this curious form in flower. It belongs to the group 

 of which my R. j^seudo-ciispidatus (cnfr. ' Primitias Monographia3 

 Rosarum,' p. 753) makes a part. The foregoing observations are 

 written in case we really have to deal with a variety of R. tomentosa, 

 but does the plant actually belong to that species ? May it not 

 rather be a form of R. corii/olia belonging to the group of R. cinerea 

 Rap. (cnfr. Prim. Mon. Ros. jd. 719) ? It is possible, and even quite 

 probable. You sent me (No. 106) a rose from Railway Bank, Niddry, 

 near Edinburgh, 29th July, 1881, which comes near Mr. Bailey's. 

 The forms of Pi. coriifolia with glandular leaves are rare, and not 

 yet understood. Your No. 106, and Mr. Bailey's plant, if they do 

 belong to R. coriifolia, constitute varieties new to the British Flora. 

 You can, I think, put on the ticket, 'veris Pi. coriifolim Fries, var. 

 prox. R. cinerece Rap.' " " I revisited the locality on July 7th, 1888, 

 and found this rose fairly abundant, and constant. The flowers 

 were just opening, and were of a full pink, rather lighter in shade 

 than Pi. tomentosa. The petals were somewhat unregular in shape, 

 crumpled at the edge, and generally the notch was ill-defined. The 

 uncination exhibited considerable variation between plant and plant, 

 and even on the same plant; the lower parts of the flowering 

 branches generally produced the canina type of hooked prickles, 

 with the enlarged base ; the prickles of the upper portions of the 

 branches were far from uniform, some being straight, and occasion- 

 ally projecting forward, while others were slightly curved, as in 

 tomentosa, and so on into a distinctly-hooked form, both with and 

 without a broadened base. There were about fifty low bushes 

 scattered over a space of about two or three hundred yards of a 

 marshy portion of the mountain-side. I collected suflicient flowering 

 specimens for the members, and have asked Mr. J. E. Griffith, who 

 was good enough to accompany me to the station, to collect fruiting 

 specimens, in the autumn, for the Club. I sent three selected 

 specimens to Prof. Crepin, who has been good enough to report 

 upon them as follows : ' I have just returned from a journey in the 

 Alps, and found your fine specimens of Rosa tomentosa Sm., var. 

 uncinata, awaiting me. After having examined these with much 

 attention, I am led to think that we have in them a form of 

 Pi. tomentosa. As you very justly say, the form of the prickles varies 

 much on the stems, where they are sometimes of typical form
