300 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
H. septentriofiale, Arv. Touv., var. amphiholiim, Lindeb. Nant 
Hebog, Llanvvrtyd, 23rd July 1907. This is the Hawkweed from 
Llanwrtyd ascribed in ‘ British Hieracia ’ (p. 69) to H. Adlerzii^ 
Almq. I believe that Rev. W. R. Linton is now inclined to view 
it as probably H. amphibolttm. — Augustin Ley. 
H. septentrionale, Arv. Touv,, var. amphibohan, Lindeb. 
-\beredw and Boughrood, Radnor, 25th June 1907. This plant 
has been sent by Rev. W. R. Linton to Enander. — .Vugustin Lev. 
IT. cacuminafum^ Dahl. Ammanford, 20th July 1907. “Prob- 
ably caciiminatnm." — \V. R. Linton. This is near the Scandinavian 
type specimens of H cacti mmatum ; differing from the British 
jdants we have been ascribing to this species in the phyllaries being 
far less clothed with glands and having their tips esenescent. — 
-A.UGUSTIN Ley. 
IT. cacuminafutn, Dahl., /. Abergwesyn, Breconshire, 23rd 
July 1907. This is the sciaphi/iim-Yike plant common in many parts 
of Britain, which has been ])laced under H. cacut/iinaitim, Dahl., but 
is not the typical plant of Dahlstedt. — .\ugustin Ley. 
IT. ? Origin Mcllte glen, S. Brecon. Cult. 3rd July 
1907. Tliis plant has been distributed before under various names ; 
but its right place in our lists remains still doubtful. Rev. W. R. 
Linton does not favour the suggestion that it can be placed under 
IT. sparsifolium, Lindeb. — Augu.stin Ley. 
II. sparsifolium, Lindeb., var. lingua, Ley. Origin West 
Brecon ; cult, ist July 1907. This ])lant readily grows by seed 
and increases in the garden. — .\ugustin Ley. 
H. rigidum, var. trichocaulon, Dahlst. Hedge bank, Howells- 
field, W. (ilos., 19th Aug. 1907. — W. A. Shoolbred. This matciies 
nicely the var. calcaricolum, F. J. Hanb. The specimens arc better 
developed and not so desiccated as the few original specimens, 
whose corymbs were probably reduced to 1-2 heads through the 
drought and the exposure of their habitat. — E. F. Linton. 
II. boreale, Fr., var. emincns (Jord.). Origin Abercdw, Radnor ; 
cult., 28th August T907. — Augustin Ley. 
II. umbcllalum, L., near var., filifolium, Back. Roadsides 
near Eltham, N. Lincoln ; 19th August 1907. — Augustin Ley. 
No. — ^V. R. ].,iNa'ON. 1 should ])refer to call this var. linarii- 
folium, Wallr., a widely spread form, from Perth and Wigton to 
Lancashire and Norfolk, rather than var. filifolium, which has yet 
narrower and more entire leaves. — E. F. L.
