in your Magazine (p. 108.), ^. mediterranea {Bot. Mag. pi. 471.), on 

 the western coast of L'eland by Mi". Mackay. The above, I believe, 

 complete the list of our native heaths, as far as the discoveries of botanists 

 have yet extended. It may be mentioned, however, that Menziesia Da- 

 beoci* {Eng. Bot. pi. 35.) and M. caeriilea {Eng. Bot. pi. 2469.) have 

 both been occasionally referred to the genus ^rica by different botanists : 

 the former is a native of Ireland, and is still known by the name of the 

 Irish heath ; the latter has been more recently discovered in Scotland. 

 Exica (Calluna) vulf;;aris, Tetralix, and cinerea occur abundantly in num- 

 berless places throughout the country ; and all three are occasionally found 

 varying with white flowers. A very pretty double-flowered variety, too, of 

 E. vulgaris, has long been cultivated in the gardens. E. vagans, as its 

 English name implies, is found in Cornwall ; particularly near the Lizard, 

 where I have seen it with deep red, pale, purplish, and white flowers. For 

 descriptions of our British heaths, I refer your correspondent to the 

 works already quoted. 



The same gentleman records the fact of his observing, in a particular 

 spot, Polygala vulgaris, with flowers of four different colours, viz. dark blue, 

 light blue, red, and white ; and he asks, "Are these four different varieties ?" 

 [species, I presume, he means,] " or are they all the same ?" They are, 

 doubtless, mere varieties of one and the same species, and all of them may 

 frequently be found in places where the plant occurs. As to the cause of 

 this change in colour, it is a mystery which we cannot explain, any more 

 than we can the cause of the colour in any flower. Yours. — W. T. Bree.
