Var. Dahlst. Streams 1,200 — 1,500 ft. Glen Shee, 
E. Perth, 14th July 1906. — W. A. Shoolbred. “Agrees closely 
with W. Yorks, plants, though diverging in some slight respects from 
the Scandinavian form.” — W. R. L. 
H. dissimile, Lindeb. Coolah Burn, Glen Beg, E. Perth, 12th 
July. — W. A. Shoolbred. The specimens comprised two forms; 
one with sharply cut leaves is the H. dissimile form of ‘ Set Brit. 
Hier.,’ the other, with less toothed or subentive leaves and fewer and 
more slender glands on the heads and peduncles, comes rather 
under H. ccesium, Fr., var. insulare, F. J. Hanb. — W. R. L. 
H. acroleucum, Stenstr., vox.^dcedalolepium, Dahlst. Riverside, 
Glen Shee, E. Perth, i6th Aug. 1906. — W. A. Shoolbred. “ I 
think this is nearer the type ; the heads in the variety are almost 
epilose.” — W. R. L. 
H. acroleucum, var. mutabile. Ley. Abundant on granite refuse. 
Mount Sorrel Quarries, Leics. The Rev. W. Linton writes, 22nd 
Oct. 1906: “ 'Fhe plant has only previously been found in S. 
Wales and that part of England.” 23rd Oct., 1906. — F. L. Foord- 
Kelcey. “ Excellent and typical.” — A Ley. Also from Pontfaen, 
Breconshire, 4th Aug. 1906. Plants such as these are not seed- 
lings but show the stature of the plant when growing on dry 
mountain banks. — A. Ley. 
H. pinnatifidum, Lonnr. Woods in the Ogwen Valley below 
Bethesda, Carnarvon; July 1904. Apparently abundant in the 
neighbourhood. — Augustin Ley. “ Agrees very closely with the 
Scandinavian plant Lindeberg’s exs. No. 74 : Dahlst. exs., i., 84, 85 ; 
‘ Hb. Hier.,’ Scand. cent, ii,, 86.” — W. R. L. 
H. Watersmeet, N. Devon, 14th June, and Upper Tawe 
Glen, Brecon, 5 th July 1906. The name I have been giving To 
these plants~is H. scanicuni, Dahl. ; but I must leave it to those who 
know more than I to decide whether it is correct —Augustin Ley. 
Upper Tawe Glen, Brecon, 5th July 1906. — W. R. Linton. 
? H. scanicuni, Dahlst. This name is used, at present, only 
provisionally, as Mr, Ley informs me, for many plants which, in ' 
Glamorgan and South Wales, were called H. diaphanotdes. It is 
very near H. irnguum, Fr. The specimens distributed were gathered 
at Ystalyfera in Glamorgan, on the borders of Breconshire, at the 
beginning of July 1906, and in the Rhondda and Aberdare Valleys 
in 1903. But the form is very widely distributed in the county, and 
is far the most frequent hawkweed there. — H. J. Riddelsdell.
