two ftyles, you obferve, are, in fact, the di- 
vifions of one ptftillum. From this circum- 
ftance, Dr. Stokes, in Withering's Botanical 
Arrangement^ aflerts, that this our common 
Hawthorn is the Cratsegus monogyna, and not 
the oxyacantba of Linnasus, as Hudfon, Rel- 
han, Lightfoot and I have made it. Dr. 
Withering is of Stokes's opinion, and ac- 
cordingly fubftitutes the monogyna for the 
oxyacantha. But the fpecific character of the 
firft is, foliis fubtrifidis acutis; that of the 
Iatter,y0//Y.f obtufafubtrifidisferratis : now the 
leaves of our Hawthorn are certainly obtufe 
and ferrated. As to the piftillum, it is fome- 
times entire, but more frequently divided 
into two flyles, and fometimes thefe ftyles 
are diftin6l down to the bottom. Lyons, in 
the MS. quoted by Relhan, fays, that the 
ftyle is firft fimple and afterwards divided. 
I doubt this facl, becaufe I have repeatedly 
found the ftyle divided before the expanfion 
of the corolla. 
There are in the laft edition of the Syf- 
tema Vegetabilum, 15 fpecies of the Crataegus, 
only three of which are found in this coun- 
try, viz. C. aria, Whitebeam tree; C.tormi- 
tS) Service tree; and C, oxyacantha^ Haw-
