Mr. Tufnail tells me in Hort. Sutton the two keep quite distinct. — 
G. C. Druce. 
Sesleria ccerulea, Scop., var. Jlavescens, Moore. Castle Taylor, 
county Galway, 1 6th May, 1892. — H.C.Levinge. “Yes.” — E.Hackel. 
“ This form of the plant grows also in Bohemia ; and Dr. Moore 
pointed out certain differences between the Irish and Scotch Sesleria 
(to which his attention had been called by Mr. Me. Nab) in the 
‘ Phytologist,’ vol. 2, p. 130 (1845 ) ) but the plant had been named 
by Opiz. and Knaf., and is coerulea^ Arduin, var. luieoalba, Opiz., 
Boh. Gew.’ p. 14, 1823. S. cczrulea^ var. flor. luteo alba “Knaf. in 
litt.” ex Bertch and Seidls’ ‘FI. B 5 h.,’ p. 492, 1836.” — Arthur 
Bennett. 
Koeleria cristata, var. gracilis^ f. humilis. See ‘Report’ for 1888. 
Near Llanfaglan Church on the beach, June, 1892. — J. E. Griffith. 
Is K. cristata f. humilis non var. gracilis^ teste E. Hackel. 
Dactylis glomerata, L., var. Freshwater Cliffs, Isle of Wight, July, 
1892. Growing with Serrafalcus Ferroyiii, Mabille, which it imitates 
in habit. Is it var. abbreviata, Bernh. ? — A. H. Wolley-Dod. I have 
the same plant from the locality given, c sheeted by Miss C. E. Palmer 
three or four years back, when I referred it to var. abbrruiata. — G. C. 
Druce. Prof. E. Hackel says “yes, var. abbreviata^ Bernh.” 
Poa alpina, L. A curious caespitose form which is, I believe, 
varietally distinct from P. alpina, occurs on the steep cliffs of 
Aonach Mor, Westerness, August, 1891. Prof. Hackel simply labelled 
them P. alpina. The type is sent from Ben Lawers. — G. C. Druce. 
“ It looks very interesting.” — E. S. Marshall. I have again called 
Professor Hackel’s attention to it, but he says it is only a dwarf form 
of P. alpina. The panicle is depauperate, but he does not yet decide 
whether it is a variety or state. The Loch-na-gar specimens of so 
called P. laxa he refers without doubt to P. alpina. Have we the 
P. laxa in Britain? I doubt. — G. C. Druce. 
P. Balfouri, Parnell. Cultivated specimens from the cliffs of 
Glen Ennich, Easterness. A distinct species, I believe. — G. C. Druce. 
P. nemoralis, L. Near Cold Ash Common, July, 1891. — G. C. 
Druce. This plant, which is referred to the type by Prof. Plackel, 
differs from our common Berkshire plant by its more spreading panicle. 
P. compressa, L. Wytham, Berks, July, 1892. — G. C. Druce. 
Festuca ovina, L., var. vulgaris, Hack., sub-var. jirmula, Hack. 
Sandy field, nr. Stow wood, Oxon, May, 1891. Named by Prof. Hackel, 
very noticeable from its straddling, rigid, culms. — G. C. Druce. 
F. ovina, L., var. paludosa, Gaud. Ambarrow, Berks, August, 
1891. — G. C. Druce. 
F. rubra, L. Type, on chalk rubble, brought from Berkshire to 
Oxford Railway Station. Plant rather gone over. July, 1891. — G. C. 
Druce. Named by Prof. Hackel. 
F. . Sandy banks by the sea, Wallasey, Cheshire, 
August, 1892.— J. A. Wheldon. oraria, Dum., which is a var. of 
F. rubral'‘ J. Gilbert Baker. “ Clearly a form of F. rubra. I think 
Herr Hackel would put it under ge?iuina, but root-material is not 
sufficient in the specimens sent to me.” — E. S. Marshall. “ rubra
