618 ON A NEW SPECIES OF HELIANTHEMUM. 
tatum. In confirmation of this idea, I shall add two particu- 
lars, which seem to possess some claim to notice. In the first 
place, culture makes no difference in that main point, the 
presence of bracteas, which is proved by a sketch of the 
cultivated specimen, kindly sent by Mr. Wilson. And, 
secondly, the above cited habitat is the only place where it 
grows in England proper; while the Helianthemum guttatum, 
such as it is seen in France and the more southern parts 
of Europe, is not found in this country, and the plant so 
called in the English Floras (especially in Smith's Flora 
Britannica) consists, in my opinion, of two species; one 
being a native of Jersey, (an island rather allied by geogra- 
phical position to the French Flora than the British,) this 
is, judging by an imperfect specimen, merely a hispid variety 
of H. guttatum; while the other is the Anglesey plant, now 
under consideration, which seems confined to a much more 
northern and very limited habitat, growing only on one spot 
in that island. The general diffusion of Helianthemum gut- 
tatum, in its native countries, renders it improbable that a 
single place in that islet should be the type of its growth in 
Great Britain. Under the conviction therefore of the 
species being distinct, I confer on it the name of the late 
Mr. Brewer, who, in Hudson's Flora Anglica, is stated to 
have been its original discoverer.
