4.58 CNICUS FORSTERI IN WORCESTERSHIRE. 
plant was not as common as the white Saxifrage (S. granulata) 
or the red Campion. In the camp at Callander it was growing 
at the very bottom of the fosse (ditch). We would not venture 
to say that it is what is generally understood by “ truly wild,” 
but it was certainly naturalized and well established. We have 
seen it in Wales, where it certainly is wild, and it is probably so 
in Devon and Cornwall. Why not in Scotland? The evidence 
is not entirely satisfactory.

On the Occurrence of Cuicus Forsteri (Smith) an Worcestershire. 
By Enwin Less, F.L.S., ete. 
I believe that the rare Cnicus Forsteri of Smith has been seldom 
heard of out of Sussex, where it was discovered by the late Mr. 
T. F. Forster; at any rate I have never met with any botanist 
who had professed to have gathered it in the Midland Counties. 
I was therefore pleased, on an excursion with the Worcestershire 
Naturalists’ Club in the present month, to find this presumed 
hybrid Thistle in a very wet pasture near Crowle, about four 
miles eastward of Worcester. In passing through this meadow, 
the grass of which was growing high and ready for mowing, I was 
first struck by meeting with the Meadow Plume-Thistle (C. pra- 
tensis), which is now very rare in Worcestershire ; and in looking 
about for more of this, I noticed that near the brook that divided 
the meadow there was an amazing quantity of the Marsh Plume- 
Thistle (C. palustris), which, scattering itself about, approached 
that part of the pasture where alone I could find any specimens 
of C. pratensis. While I was gazing around, I remarked a sin- 
gular group of Thistles with widely-spread panicled flowers,—a 
few crowded together at the summit, as in C. palustris,—but the 
stem not winged, and only cottony, as in C. pratensis. This 
Thistle, on taking home and comparing with Smith’s original 
description in his ‘English Flora,’ I found to coincide exactly 
with C. Forsteri. 
Though it must be an uncommon case to find a hybrid Thistle, 
yet Sir W. J. Hooker and Mr. Babington, as well as those bota- 
nists who have seen the plant, now generally agree that C. Forsteri 
is a hybrid between C. pratensis and C. palustris. The Thistle I 
found as above certainly seemed inicrmediate between the two
