R. calvatus, Blox. Yeldersley I^ane, near Shirley, Derby, 
8th Aug. 1904. — W. R. Linton. “Yes, quite typical.” — W. M. 
Rogers. 
-R. calvatus, Blox. f. calvula, W. R. Linton. Shirley, Derby, 
ist Aug. 1904. — W. R. Linton. “Yes, clearly a small form of 
R. calvatus, Blox., as previously issued by Mr. Linton.” — W. M. 
Rogers. 
R. leuca?idrus, Focke. Nevvent Woods, Glos., nth Sept. 
1903. Mitcheldean Meend, W. Glos., i8th Aug. 1904. — -Augus- 
tin Ley. 
R. thyrsoideus, Wimm. sp. coll. Lizard Peninsula, W. Cornwall, 
1604: — Lizard Down, July 19; Mullion Cove, July 29. Most 
abundant locally, and apparently one of the prevailing brambles 
over a considerable part of the Peninsula. A peculiar form, with 
a great tendency to lose the felt from the under surface of the 
leaves. In some respects nearer to R. rustica?ius, Merc, (very 
common throughout the district) than is usual with this species, 
and yet everywhere keeping quite distinct from it. New for Corn- 
wall. — W. Moyle Rogers. 
R. thyrsoideus, Wimm. Barkly, Leicestersh., August 1904. — 
W. Bell. Alveston Heath, Warwicksh., 20th Sept. 1904. — J. E. 
Bagnall. 
R. argcntatus, P. J. Muell. Lizard Downs and Mullion Cove, 
W. Cornwall; July 16 — 29, 1904. Fairly frequent and very vari- 
able ; in some instances distinguishable with difficulty, — as else- 
where in the W’est of England, — from the less glandular forms of 
R. micans Gren. and Godr. Between Heytor and Liverton, parish 
of Ilsington, Dartmoor, S. Devon ; in several spots, but hardly 
common; August 1904. — W, Moyle Rogers. Mr. Rogers writes, 
“Two names in this note also undergo change, R. argcntatus 
becoming R. Godronii, Lee. & Lam., and R. mica?is becoming 
R. hypoleucus, Lef. & Muell.” 
R. pubescens, Weihe. — Roadside near Byfleet, 23rd July. No. 
1,235, Wisley, 31st July 1904, No. 1,246. — Mr. Rogers 
tells me this plant is nearer the continental type than anything he 
has seen in Britain. It appears to be not unfrequent west of Wal- 
ton, and is conspicuous by its pale green colour, with narrow remark- 
ably long pointed leaflets, and much hooked or deflexed prickles. — 
A. H. Wolley-Dod. “Seems very near to the German type (like 
most of the R. pubescens that Major Wolley-Dod finds near Walton- 
on-Thames), though differing from it slightly in the glabrescent 
stem, rather more incised leaflets and (more conspicuously) in 
the ascending sepals, described by Dr. Focke as “ Concava re- 
flexa.” — W. Moyle Rogers.
