26. Rosacese. 



Prunus, Linn. 110. 



419. spinosa, Linn. Sloe. Draeneu ddii. 

 Common. Abundant. Native. Septal, &c. 



Mr. T. H. Thomas reports a fasciated, dwarf prostrate form 

 from Port Eynon, Worms Head, and Rhossili, Gower. 

 b. niacrocarpa,Walir. Apparently this variety is widely distributed 

 all over the Vale, and has been recorded under 420. The flowers 

 in particular differ much in the size of the corolla. There may be 

 more than two forms of 419. 



420. insititia, Huds. BuUace. Eirenen bulas. 



Frequent. Dinas Powis, Duffryn Golwg, Pencoed, &c. J.S. 

 Barry. D. Lavernock. H. Barry Island; Six Wells. J.S. (2). 

 Llangenydd ; Pantyffynon ; Rhigos ; Baglan ; Bridgend ; Marcross ; 

 Llandow ; St. Donats ; Cowbridge ; Wenvoe ; Cadoxton. Ridd. An 

 unsatisfactory record, probably based chiefly, if not entirely, on the 

 variety macrocarpa, Wallr. of No. 419. The Editor has examined 

 thousands of specimens of P. spinosa, from most of the above localities, 

 varying greatly in flower and fruit, but has never seen the BuUace 

 in Glamorgan, nor found anyone who could furnish him with a 

 specimen of the fruit. Several of our correspondents know the true 

 BuUace well. 



422. Avium, Linn. Gean. Ceiriosen ddu. Sirianen ddu. 

 Local. Frequent. Native ? Sylvestral. 



Frequent. Llandaft, Penarth, Cwm George, Coedriglan, &c. 

 J.S. Barry. D. Merthyr district. E. and F. Common in Crowley 

 Woods, Gower. L. PwUypant. V. Near Aberdare. Ridd. Cow- 

 bridge to Bridgend ! Llandough ! Llanilid ! This tree grows in so 

 many places in the Valq of Glamorgan, that one may see scores of 

 them in a twenty-mile ride in spring, when the trees are in blossom. 

 Their distribution makes it all but certain that they have seldom 

 been planted. There seems no valid ground therefore for excluding 

 this species from the list of true natives. Ed. 



423. Cerasus, Linn. Dwarf Cherry. Ceiriosen. Sirianen. 

 Rare. Scarce. Native ? Septal. 



Taff's Well. J.S. Llangenydd; Penllergaer; Wenvoe. Ridd. 

 F. of G. 



The following records probably belong to 422, although sent in 

 under 423. Knip Wood, near Southerndown. Miss B. Pendoylan. 

 /. Common. H.E. Coedriglan. G.T. This species does not develop 

 into a tree. Leighton says it reaches 3 to 6 feet in height, Bromfield 

 6 to 8 feet. The status of this species in Glamorgan is at least as 

 doubtful as that of the preceding one.
