40 THE JOURNAL OF BOTANY 
NOTES ON THE FLORA OF FLINTSHIRE. 
By A. A: Dauuman, F.C.S. 
‘Durive the past two years I have devoted ae atten- 
tion to the vegetation of Flintshire. In this period I have 
travelled some fifteen hundred eies on foot sone in investi- 
gating the flora of the county, and there are now comparatively 
few localities in aba which have not been visited. Of course 
togamic portion of the flora, and there is no doubt that 
pabthar investigation of several promising localities will be well 
repaid. As many new facts have come to light it may be well to 
place some of this work on record, and I venture to think that the 
present paper, in conjunction with the two previous contributions 
published in this Journal for 1907 (pp. 1388-153) and 1908 (pp. 
187-196, 222-230), will go far towards rescuing this much- 
a county from its position of Sheer oblivion. 
t August and September I spent some six weeks in the 
siecty: and the time was mainly totaal to a systematic investi- 
gation of the flora. Some attention was also paid to the ecology, 
pollination, and insect visitors of various speci = aspects 
of the subject may perhaps be dealt with in a separate contribu- 
tion at some oe date. In the cea paper I have confined

paper, as this aspect of ihe Flintshire Flora has hitherto received 
scant attention. Many of these waifs and strays are of course 
very ephemeral, but it is perhaps as well that they should be 
noted. Asan instance of the evanescence of many of these plants, 
Ambrosia i may be cited. In 1906 this North Ameri- 
ies was growing in considerable quantity about the ruined 
mill behind Greenfield Abbey. There was at that time a large 
d 
example. On the other hand, aliens are sometimes ene

along the estuary ene Saltney to Bagillt.. On the Dee Embank- 
ment for a distance of half a mile or so north-west of the Bettis- 
field Colliery it is the predominant plant. Here it ae in large
