typical plant from any English or Scottish locality” (p.27). This species is
scarcely found in Scotland, and this record does not appear in Edees & Newton
(1988); both D. E. Allen and myself consider it to be an error, perhaps for
R. pyramidalis Kaltenb. a similarity to which Rogers discusses.]
R. lindleianus Lees: In Scotland this is a western species and so Rogers’
statements that he found it “by L. Earn, in great quantity” and “by L. Tay,
abundant” are surprising. In 1998 some were present by both shores of L. Earn,
particularly on its north-west side, but only one bush was seen at the west end
of Loch Tay. His Stirlingshire dried specimens all came from Loch Lomond.
R. rhamnifolius Weihe & Nees (sp. collect.): Under this name Rogers
mentioned two brambles he was unable to name satisfactorily, one on
Callander Crags which he considered to show “rather closer affinity with R.
pulcherrimus” = R. polyanthemus Lindeb. – and in fact this may have been the
species involved, as an atypical form was seen there in 1998. The other, found
at Stirling and which he assigned to R. cardiophyllus Lef. + P. J. Mueller, has
been determined by A. Newton as his R. wirralensis, a member of the series
Mucronati.
R. nemoralis P. J. Mueller: Rogers did not find this growing, his
determination being made from material gathered by his son from Black Hill,
south of Callander; it is in fact R. wirralensis (det. D. E. Allen, conf. A. Newton).
It is likely that “var. glabratus” from Wester Glen, Gargunnock was also that
species. It should be noted that what Rogers normally understood to be
nemoralis was the bramble now called R. oxyanchus Sudre; see also R. villicaulis
Koehl. var selmeri, below.
R. pulcherrimus Neuman = R polyanthemus: In the west and especially the
southwest, this is abundant, but it is much less so in central and eastern
Scotland, so Rogers’ assessment that it was “not very abundant” was correct.
Found in small quantity in 1998 on Callander Crags, by L. Venachar and by the
Lake of Menteith.
R. scheutzii Lindeb. = R. errabundus W. C. R. Watson: A new species in the
living state to Rogers, who sent specimens to Focke for determination along
with various notes, which he reproduces. He considered it to be “one of the
most abundant and most constant brambles seen by me in Mid-Scotland”, an
accurate summing-up of its position both then and now.
R. lindebergii P. J. Mueller: Seen by Rogers in only two localities, “in the
higher part of the Callander Crags”, i.e. by the track above Bracklinn Falls car
park where it still grows, and from the Aberfoyle area. In 1998 it was noticeable
in several places along the Loch Earn South Road. This bramble seldom occurs
in any quantity and avoids the more acid soils; it is scattered throughout
central and south Scotland.
(R. dumnoniensis Bab.: “extraordinarily abundant” near Oban, which is still
the case but well outwith the Trossachs.)
R. villicaulis Köhler. var. insularis (F. Aresch.) Rogers = R. septentrionalis W.
C. R. Watson. Rogers was delighted to see this species, which he opined was
