314 Miscellaneous. 
tleman I have recently had an opportunity of examining that speci- 
men, and find that it is not D. plumarius but D. superbus, which is 
so frequent an inhabitant of gardens that I think it certainly cannot 
be considered as an indigenous plant without further proof than we 
as yet possess. Mr. Mackay’s description appears to have been 
drawn from the true D. plumarius. 
in Mr. Leighton’s ‘Flora of Shropshire’ (p. 188.), D. plumarius is 
introduced upon the authority of specimens gathered upon the walls 
of Ludlow Castle and Haughmond Abbey, in both which places it 
is very plentiful, as I know from personal observation, and has quite 
as good a claim to be included in our lists as D. Caryophyllus, the 
only certain stations for which are the walls of the Kentish Castles.

Sinapis Curerrantuus, Koch.—Specimens of a plant from near 
Penard Castle, Swansey, have been distributed by myself and others 
under this name, which turn out, upon more careful examination, 
to be only S. Monensis.—See Prim. Fl. Sarn., p. xiii. ‘The Jersey 
plant is the true S. Cheiranthus, which has not yet, I believe, been 
found in England.—Cuaruzs C. Basineron. 
SAXIFRAGA UMBROSA, 
Brislington, near Bristol, Nov. 24, 1840. 
Sir.—It is stated in the Review of Mr. Baines’s Flora of Yorkshire 
(Ann. Nat. Hist. for Nov. p. 216.), that Sexifraga umbrosa is *‘ nota 
northern plant,’ but that it is found ‘‘in the west and south-west 
of Ireland, in as mild a climate as any part of the British islands 
affords.” It may be worth mentioning that it was brought to me 
some years since from Clovelly, when I doubted its being truly wild. 
I this year have had an opportunity of verifying the locality myself, 
and from the circumstances of its being a mile distant from any gar- 
den, and that no other cultivated plants are to be found in the course 
of the road near which it grows, I am much inclined to admit the 
station as a true one. I found it on the left-hand side of the Hobby 
approaching Clovelly near a little bridge. 
I am, Sir, obediently yours,

This beautiful flower has always been referred to Pentandria Mo- 
nogynia, but on examining several plants I was struck with observing 
that the terminal flower of four out of eight specimens had six equal 
perfectly formed stamens. This fact does not appear to have been 
observed, as I do not find any reference in the Synoptic Tables to 
plants under Hewxandria Monogynia. It is also remarkable that the 
terminal flowers should have the anomalous number; as in general 
the student is directed, if he is under any difficulty on account of 
the difference in the number of stamens in the flowers of the same 
plant, to be guided by the number of the terminal flowers. 
The corolla is six-lobed, or rather formed of six petals soldered 
together, as they separate very easily one from the other, and the 
calyx is six-leaved, with a small scale at the centre of the base of the
