The prevailing form in this district is the C. raonogyna 
J acq. ; it is that of which all our quickset hedges are 
made, and is said to flower a fortnight later than the third 
sub-species. 
The second form, the C. kyrtostyla of Fingerhuth, I col- 
lected on the 25th May, 1867, in Botany Bay Wood (Mersey 
Province, County No. 59 of Watson) on the path from 
Barton Moss to Worsley, where it forms several handsome 
trees. It attracted my attention at once by the large pro- 
portion of its flowers which possessed two styles, and by 
the comparative large size of the corymbs ; its fruit I have 
not been able to examine, as the ground in which it occurs 
is preserved by the Earl of Ellesmere, and is accessible only 
by a written order. 
The addition of the third sub-species, C. oxycicanthoides 
Thuill., to our flora., is the most noteworthy, and is due to 
the keen sight of Mr. John Hardy, who detected a single 
bush of it on the 27th August last, at Marple (Trent Pro- 
vince, County No. 57), on the right hand side of the high 
road from the railway station, a little past the uppermost 
lock of the canal. The leaves of this plant are of consider- 
able size, being about twice as large as those of a plant in 
my herbarium from Hampstead, collected by Dr. J. Boswell 
Syme, and excepting that the leaves are glabrous, the 
Marple plant appears to agree with the variety /3 mctjus, 
Hobkirk. The fruits on the specimens exhibited are small 
and urceolate in form, but they were not mature at the 
time they were gathered. For some seasons back I have 
unsuccessfully sought for it in this neighbourhood, and at 
present it is not ascertained to occur in the Mersey pro- 
vince, though it will doubtless be discovered on a more 
careful search. The most obvious character for determining 
this sub-species in the absence of the flower or fruit, is the 
arrangement of nerves in the leaves, which are arcuate, with 
the extremities turned towards the midrib; in the two
