elevation ; I have never found it on the cliffs. When well developed 
it is unmistakable. — A ugustin Ley. 
Hieraciicm vuigatum, var. cacuininuni. Brecon Beacons, 23rd July 
1902. This was gathered at the original station for caaiminum, as 
Mr. Ley informs me. When gathering it I took it to be H. orime/es, 
and now on comparing my specimens of H. cacufnmum and H. orhneles 
they are certainly very closely allied, and had best be arranged as 
orimeles with variety cacuniinum. — W. F. Linton. 
H. diaphanoides, Lindeb., teste A. Ley. Aberant, Aberdare, 
vice-county 41, July 1902. Mr. I.ey refers all these plants to the 
same species. He says “it differs much in size and in breadth of 
leaves, but I believe all to fall under type diaphanoidesP The plants 
differ “ little in clothing of heads, and 1 feel sure are all to be assigned 
to one species and one variety. H. diaphanoides, in my opinion, is 
often with difficulty distinguished from H. dc^dalolepium, and the latter 
ought to be taken from H. vulgatum and associated with it.” The 
difficulty of distinguishing is apparent to one who gathers the plants 
in situ, but here at least (Aberdare) on the railway embankments, 
coal waste, etc., where both plants abound, H. diaphanoides is 
decidedly later in flower, by as much as a fortnight. — H. J. 
Riddelsdell. 
H. diaphanoides, Lindeb. Upper Tawe, county 42, July 1902. — 
H. J. Riddelsdell. 
H. diaphanoides, Lindeb. Grassy .stony banks at Beasley Falls, 
near Ingleton, West Yorkshire, 7th July 1902. The name was 
suggested to me by Rev. W. R. Linton, and is, I believe, undoubtedly 
correct. — Augustin Ley. “Yes, it agrees with much that we have 
so named in this country, but is scarcely identical with the Scandina- 
vian type.” — F. J. Hanbury. 
H. rigidum, Hartm., variety pullatian, Dahl. Railway cutting and 
banks Glyn Collvvng, just to the north of Torpantau Tunnel, Brecon- 
shire, 24th July 1902. See ‘Report of B. E. C.,’ 1900, p. 639. The 
present plant is from the same locality. — Augustin Ley. 
H. rigidum, Hartm., variety trichocaulon, Dahl. Origin, Parkstone, 
Dorset, and I believe certified by M. Elfstrand ; garden, 30th July 
1902. — Augustin Ley. 
H. rigidum, var. tridentatum, Fr. Pembridge, Herefordshire. 
“ Rather var. acrifoliu 7 n, Dahlst.” — W. R. L. 
H. rigidum, Hartm., var. scahrescens, Johanss. Origin, Glyn 
Collwng, Breconshire (close to the station for var. pul/atum, Dahl., 
mentioned above); the original plant named by M. Elfstrand; garden, 
30th July 1902. — Augustin Lev.
