place them as varieties, under either or both of the two 

 species. I found numerous plants, and thus obtained a 

 series of the forms, on a heath near Truro, which was then 

 (1831) in process of enclosure ; and looking at the map, I 

 think it must have been on the road towards Redruth ; but 

 I was an utter stranger to Truro at the time, and was 

 strolling along whither chance might lead. The Rev. C. 

 A. Johns has recently given me a living plant, raised fi-om 

 cuttings of E. Watsoni, but not exactly the form described 

 by Bentham, taken from a single shrub of it which was 

 found by Mr. Borrer (in 1847.?) "on the right hand side 

 of the lane which leads from the Foundry at Perran to the 

 plantation in which E. ciharis grows so abundantly." It is 

 highly probable that E. ciliaris had been really known as a 

 native many years ago, but again lost sight of until re- 

 discovered by Mr. Tozer. In Curtis's Botanical Magazine, 

 t. 484, it is remarked of this Heath : " C. Bauhin, mis- 

 takenly, calls it anglica, which has given rise to the idea of 

 its being an English plant, but it is not." I have a speci- 

 men of true E. ciliaris, obtained by Mr. John Ellis from a 

 garden shmb, which, he was informed, had been trans- 

 planted from a common near Farnham, in Surrey. It is 

 probable that there was some mistake about the individual 

 shrub, for E. ciliaris is killed down by very severe winters, 

 in my own garden, in the same county ; and it would there- 

 fore seem to requii'e a milder climate for its natural habitat.
