Quercus, Linn. 379. 



1392. Robur, Linn. Common Oak. Dar, Derwen, Mesbren. 

 Common. Abundant. Native. Sylvestral. 



The three varieties — a. pendunculata (Ehrh.), b. intermedia 

 (D. Don), and c. sessiliflora (Salisb.) occur ; the first and third being 

 about equally widely distributed, but the second relatively rare. 

 Often planted, seldom producing fine specimens. Ed. " A large 

 hollow tree at Ty-draw, Treherbert, probably a portion of the ancient 

 Rhondda valley woodlands." T.H.T. " A very perfect chain of 

 varieties between pedunculata and sessiliflora about Pengam and 

 Gelligaer." T.H.T. 



Fagus, Linn. 381. 



1394. sylvatica, Linn. Common Beech. Ffawydden. 

 Common. Abundant. Native. Sylvestral. 



This species, although often planted, is clearly native on the 

 Old Red Sandstone and Mountain Limestone ridges between Ton- 

 gwynlais and Draethen. The beech holds its own here, even in the 

 absence of planting, seedlings being abundant.
