 Frequent about Llanfair and Llanbedr, mostly in hedges. Two

 considers them to be this species, though varying slightly from the 

 type in bemg less hairy, and the terminal leaflet with sides less 

 markedly parallel. — R. mucronatus Blox. By the Afon Artro, above 

 Llanbedr; scarce. — Pi. Borreri Bell- Salt. On rocky slopes one 

 mile N.E. from Drwsynant Station. "The true R. Borreri Bell- 

 Salt., but less glandular than is usual in the south ; a form varying 

 very slightly towards var. dentatif alius," W.M.R. Cwm Bychan. 

 Another plant from Rhydymaen and towards Aran Mawddwy Mr. 

 Rogers considers " a good deal like Borreri, but seemingly a distinct 

 form nearer the RaduUe." — R. j)odophyllus P. J. Muell. Cwm

 which will probably receive a varietal name. — R. durnetorum a,, ferox 

 Weihe. Corwen. — Pt,. corylifotius Sm. Llanfair. — R. ajinis x ^ in-
