5. North-east District, Banks of the Canal between Swindon and 
Cricklade. Very local in Wilis, and occurring but sparingly in 
the above localities. About 1 foot high. Leaves waved, toothed, 
and spiny, whiter beneath than in any of the preceding species. 
Flowers solitary. An interesting form of this plant was found a 
few years since, at Penhill near Swindon (Dis/. 5), by the late 
Mr. S. P. Woodward (C. Woodwardii). It is now considered a 
hybrid between C. acaulis and C. pratensis, varying extremely in 
appearance, but always more nearly resembling the latter than the 
former, so that it may be merely an extreme state of it. Some of 
the forms bear a very close resemblance to C. ‘uberosus.

vol. iii. This is the only locality at present known for this most 
distinct and handsome species in England, where it formerly grew 
in antl abundance, but of late years has become remarkably 
searce. Luxuriant forms of C pratensis, and C. acaulis, have not 
unfrequently been mistaken for it, in the other parts of the county. 
For further remarks on C. éuberosus, I wouid refer to the Society’s 
Magazine vol. iii., p. 249.
