Niciiolson lias contributed a good supply this year from Hampstead 
Heath. 
Specularia huhrUa. Stackyard at West Newton, Oheviotland, 
A. Beotherston. New to Northumberland. 
Teucriiim, Botrijs. A supply sent again this year by Mr. Beeby 
from the Sanderstead station. 
Mentha ])ubesce7is. Pengersick Castle, J. Cunnack ; and stream 
on Pra Sands, nearHelston, Cornwall, J. Bales. Tinsis the first time 
we have had a supply of this interesting mint, which "was gathered 
a generation ago in the neighbourhood of Penzance by Mr. Borrer, 
but has been long sought for in vain by the resident botanists. 
Acanthus moUis. Thoroughl}'’ established on a hedge-bank ait 
Treath Manaccan, Cornwall, growing with Allium Ainpeloprasum, 
W. B. Waterfall. 
Orohanche elatior. It seems quite clear now that the Epsom 
Orobanchc, which has been called lucorum, is only elatior pure and 
simple. Mr. A. Bennett sends it this year from “ fields between 
the town and downs, proceeding from the back of the grand stand 
towards the town of Epsom.” 
Solanum nujruni. A form with the fruit bright green when ripe 
(5. lute.o-virescens of Gmelin), from rubbish-heaps at Mortlake, 
Surrey, G. Nicholson. 
Veronica Buxbaumii. A variety with very hairy stems, flowers 
smaller than usual, and fruit-carpels not rilibcd till the plant is 
dried, from waste ground at Kew, G. Nicholson. 
Si/mphi/tuni asperrimum. The introduced British plant which 
has been so called by Babington in ‘ Flora Bathonensis,’ and Dr. 
Boswell in ‘ English Botany,’ of which Mr. Flowm’ sends us a good 
supply this year from the long-known station in the neighbourhood 
of Bath, and Eev. W. H. Purchas from Grange Mill, near Wirks- 
worth, Derbyshire, is evidently not the true wild S. asperrimum , 
M. B., of the Caucasus, but a garden hybrid between that species 
and 8 . offidnale, which is often planted for forage, and which 
is most likely 8 . peregrinum , Ledeb., FI. Boss., vol. hi., p. 114. 
8. asperrimum is a plant that grows five or six feet high, with 
stems densely clothed with very short, rigid, bristly pubescence, 
maii}^ of the bristles springing from wfliite calcareous tubercles, 
leaves rough over the face with bristle-pointed Avhite tubercles, 
like Anchusa italica, lower leaves of the flowering branches OAuate 
and contracted suddenly at the base, and a floAver-calyx not mor.; 
than one-eighth of an inch long, with linear-ob’ong obtuse teeth 
not longer than the tube. The naturalised hybrid has much less 
bristly stems, leaves without white tubercles on the face, lower 
leaves of the flowering branches both absolutely narrower and 
narrowed more gradually at the base, and a flower-calyx lilie that 
oi officinale, with acute linear teeth twice as long as the tube. Mr. 
Flower tells me that the Bath plant grows sometimes to the height 
of a man, so that it is not inferior to the true asperrimum in stature, 
although in its leaves and flowers it seems much nearer to officinale. 
We have the true asperrinmm in the Kew herbarium from the 
neighbourhood of Stirling, gathered by G. Thomson.
