Cybele Britannica” (Part III. p. 510), reports one, the 
C. oxyacanthoides of Thuillier, as being ascertained to grow 
in the Thames, Humber, Tyne, and East Highlands pro- 
vinces. It will doubtless be found in other provinces, and 
amongst the rest the Mersey province, in which the only 
species hitherto recorded is the common C. monogyna of 
Jacquin. 
From the specimens now exhibited it will be seen that 
the three segregate species just referred to occur within the 
limits of the Manchester Flora, and as some confusion seems 
to have arisen in their nomenclature, it will be desirable to 
give, briefly, the characters by which they may be separated 
from each other. Similar confusion exists amongst conti- 
nental authors ; thus, Boreau, in his Flore du Cent. (T. 2, 
p. 234), makes the C. oxyacanthoides of Thuill. a synonym 
of C. monogyna Jacq., while Koch, in his Synopsis (p. 303), 
and Grenier and Godron, in their Flore de France (T. 1, 
p. 567), refer it to the C. Oxycicantha L., although they 
recognise Jacquin’s plant.
