g8 The Flora of Glamorgan. 



No. 868 has been recorded from E. Moors, Dinas Powis, Newton 

 Nottage, Ilston, Cowbridge, Aberthaw, Aberafan, and Barry Island, 

 always as a typical alien. 



Serratula, Linn, 232. 



870. tinctoria, Linn. Common Saw-wort. Dant y pysgoden, Lliflys 

 cyffredin. 

 Common. Abundant. Native. Sylvestral, etc. 

 No record yet from the valley of the Afan. 



b. monticola (Boreau. ) Mynydd Garngoch ; Fedwhir, near 

 Aberdare. Ridd. 



Centaurea, Linn, 233. 



872. nigra, Linn. Black Knapweed. Pengaled leiaf benddu. 

 Common. Abundant. Native. Pascual, etc. 



The distribution of the radiate and non-radiate forms has still 

 to be worked out, especially to discover whether certain districts 

 produce one form only. The non-rayed form appears alone in many 

 districts, but the radiate form is apparently accompanied by the 

 non-radiate. However, I noted radiate forms exclusively at Ewenny 

 Down in 1908. Experimental cultures are required to determine 

 accurately the relationships of the forms. 



873. Scabiosa, Linn. Greater Knapweed. Crammenog fwyaf, Pen- 



galed fwyaf. 

 Local. Abundant. Native. Agrestal, rupestral, etc.

 separate citation of the records. Aberdare ; Hirwaun ; Vale of 

 Neath. W. A record requiring confirmation. Ed. Penllergare.

 Paviland ! Ridd. 



874. Cyanus, Linn. Corn-flower. Crammenog yr yd. Penlas yr yd.

 Barry Island. D. Barry. M.A.D. St. Fagans. V. Merthyr. 

 E. and F. Gowerton ; Port Talbot ; Aberdare ; Mountain Ash. 

 Ridd. Never, I believe, establishing itself anywhere in Glamorgan. 



No. 877 occurs as an alien near some of the docks. The record 

 in Watson's Topoaraphical Botany should be excluded.
