THE RUBI OF GLAMORGANSHIRE 91 
other labours is the production of the following list, which places 
our knowledge of the Glamorgan brambles upon a satisfactory foot- 
in Mu ch, f course, remains to be done, sareadlany in the 
expansion of locality records, and in the discovery of new forms ; 
but there is enough already to prove that the coal measures of the 
county are especially ae: and that the distribution of forms shows 
interesting links with the oon h-west of aoe with the Severn 
and. &. 
rainage area, and with ulcatus, cariensis, iricus, 
dentatifolius, vestitiformis, eg Ryne are cases in point. The eo 
gaps in the list are (besides local forms known to occur, e.g. in 
Breconshire, and therefore to be expected here) R. carpinifolius, 
Lindebergit, a egyceie: mucronatus, and Radula forms. It will be 
noticed that the new forms described and published by Messrs. 
Rogers and Ley in n this Journal (pp. 58-60) are of high importance 
in connection with the present list 
The localities are ‘iitanb upon the plan of a ninefold division 
he divi ree with the dra: 
of the county ivisions, as a » ag e drainage 
system. The arrangement, though probably as d as any other 
for geographical purposes, is still an arbi ak one. Division No. 1 
Loughor; 3, of the Tawe; 4, ‘of the Neath ; 6, -Afho = *. 6, 
(s Ddaw; 8, Taff and Ely; 9, Rhymney. Xo. 8 is far the ene 
* the divisions, and (along with No 4) has been more carefully 
orked than any of the others. srs richness of its bramble flora 
say probably be estimated with e adequacy from the fact that 
within an area of three miles diameter, including Abernant House, 
Aberdare, over forty named forms, including five ae have 
been found, and others of interest ais seFin determinatio 
he numbering and arrangement of the forms in this list agree 
with those of Rogers, Handbook of British Rubi. It will be realized 
mark of exclamation (!). It follows that nearly every form among 
the fruticose eas s here recorded bears his authority; many 
localities do n 
roe oot or confirmations of old uncertainties, are starred.
