EUBIACEiE. 



RuUa 'perecjrina. Common in woodland hedges. Along the sea- 

 coast near Bangor. 



Galium verum. Abundant on dry ditch-banks. 



G. palustre. In some places this plant is found quite in the water, 

 but usually in drier situations. Common in many of the 

 woods here. 



G. uliginosum. A rare woodland plant, that is not nnfrequently con- 

 founded with G. paluslre. From this plant it may, however, 

 be distinguished by the leaves, which are six or eight in a 

 whorl, whereas those of G. palustrc are usually four or five. 



G. saxatilc. Plentiful in heathy woods and plantations. 



*G. mollugo. In shady thickets along the Pass of jSTant Francon. 

 Not a common plant.

Valeriana dioica. Sparingly in marshy ground along the banks 

 of the Cegin river. 



V. officinalis. Frequent in rather damp woods. 



V. pyrcnaica. Plentiful in two of our woodlands. It is a very 

 ornamental plant, attaining a height of si.x; or seven feet and 

 with leaves five or six inches in length. It is by no means 

 particular as to situation, but prefers and attains greatest 

 perfection in rather damp ground ; indeed, the largest specimens 

 I know of are growing in a shady wood alongside a mUl 

 stream. 



Valeriandla olitoria. In waste parts of woods, abundant. 



V. Auricula. Sparingly distributed. 



*V. dentata. Usually in company with the latter species, but very 

 rare.
