Hieracium. Near Castlethorpe, Bucks., on the railway cutting, in 
considerable quantity. It appears to be a hybrid of H. Pilosella, but 
the Pilosella group is a most puzzling one. H. Pilosella was growing 
in the locality, but the only other species within half a mile was the 
ne.xt but one. Both are almost certainly of foreign origin, but 
are now completely naturalised. — G. Claridge Druce. “ The 
specimens agree with H. flagellare, Willd., as cultivated in Berlin 
Botanical Gardens ; = H. stolofiiflorum^ Wimm. (non W. K.).” — 
E. F. and W. R. L. 
H. pratefise, Tausch. Cult. Sellack, Herefordshire, 28th June 
1899. Origin? Root received from Mr. Griffiths’ garden, Bangor. — 
A, Ley. 
H. . This occurred in considerable quantity on the railway 
embankment in Hanslope parish, Bucks. It is allied to, if not 
identical with, H. prcEaltiim. July 1899. — G. Claridge Druce. “AT. 
praaltum^ Vill.” — E. F. and W. R. L. 
H. lasiophyllum, Koch, var. pla}iifolium, F. J. Hanb. Origin, 
Great Doward Hill, Herefordshire; cult. June 1898. I believe this 
plant to be rightly placed under H. lasiophylbcm, Koch. The wild 
plant has its leaves even more intensely glaucous-green than the type, 
but this colouring diminishes considerably under cultivation. — A. Ley. 
p[. hypochcvroides^ Gibson, var. cyathis, Ley. Limestone cliff near 
Cefn Coed, Breconshire, 6th June 1899. The original station. I 
wish to say about this plant that, though rightly I believe placed 
under P[. hypocluvroides^ it makes a decided approach to H. lasio- 
p/iyllum^ Koch. — A. Ley. 
H. platyphyllum, Ley. Origin, 1 )aren-r’-Esgob, Breconshire and 
Monmouthshire; cult, ist July and ist August 1898. No noticeable 
difference produced here by cultivation. Wild plants are often nearly 
as large as the ones now sent. — A. Ley. “ I notice that Mr. Ley now 
writes this H. cyathis and H. platyphylhuii as if they were full species, 
and not varieties, in the first case of H. diaphanum, in the second of 
H. hypochcvroides, and in the last, rather doubtfully, of H. pollinaj'ium. 
Does Mr. Ley think all three are good species, and, if not, under 
which .species does he put H. plaiyphyllumT'' — G. Claridge Druce. 
//. murorum^ Linn., pellucidum, Liestad. Oolitic hills, Dursley, 
Wb Gloucester, 8th Tuly 1898. — I. W. White. “Seems right.” — 
E. F. and AV. R. L. 
H. murorum^ Linn., var. sanguineum, nov. var. Dyffryn Crawnon, 
Brecon, 27th June 1898. See ‘Journ. Bot.,’ 1900, p. 4. A few 
specimens of this plant, which is now possessed by most of the 
members. — A. Ley. 
H. vulgatum, Fr., var. glaucoznrens, Dahlst. Great Doward Hill, 
Herefordshire, 15th June 1899; Symond’s Yat, W. Gloucester, same
