Besides the typical form (that found in Britain), subvarieties
Iciophylla, vulpioides [F. vidpioides Schur.), and puberula are men-
tioned (p. 131).
This may be a suitable opportunity for pointing out that the
Festuca list in the ' London Catalogue,' ed. viii., needs some
revision. There are two different plants under the one name
of F. loliacea Huds. ; and F. fallax, if retained as a species at all,
is of Thuillier, not of Hackel. Its reduction to a var. of rubra
seems, from an examination of specimens named by Dr. Hackel,
to be more agreeable to facts {vide Mon. p. 142). The census-number
of F. duriuscula auct. augl. {F. rubra, genuina, of Hack. Mon.).
appears to have been transferred bodily to fallax, which is, on
present knowledge, a decidedly rare British plant. Among a large
series of Surrey forms, I have not succeeded in discovering it ; and a
friend's experience was, I understand, the same.
" Eu-rubra " will
doubtless prove to be common in every one of the 112 Watsouiau
vice-counties. Is anything definite known of F. dumetorum L.
(reduced in Hack. Mon. to a subspecies) as an English plant ?
