PLANT NUTES, ETC., FOR 1924. 445
Gavery by Miss Knowles uf a note by the late J ames Britten III J OU1'­
Jluj of jJotany 2G, 1872, calling attention to the remark in DC. Prod.
vii., 656, that the plant's distribution is " in lIlontibus Corsicae,
Sal'diniae, et Hispaniae australis (Boiss. 1), etiarn in Hibermia boreuli
(Lloyd in Herb. Hooker 1)" Mr Britten added that the spec:men
was in the Kew Herbarium, and that there was no doubt of its identity
with B. stricta; it is labelled in Sir W. J. Hooker's hand, "North
of Ireland! Dr Lloyd, 1834." Dr Praeger now hopes that the plant
may prove to be actually indigenous in the north-east of Ireland, as
one of the species of the" Mediterranean element," on the an8,iogy
of Glyceria festu).weformis, This analogy ho,wever is based on the
ueduction that the Strangford Lough plant is G. jestucaejormis, but
Hackel and other distinguished critical botanists decline to accept
that suggestion and to me it is only a variety of the polymorphic
UZyce1'iu maritima which I named var. hibernica. It is closely allied
to G. F01JJcaudii (Hackel). H. te'rminalis Salisb. is a most unlikely
Hibcrnian plant. One might as well claim E. 11.sitanica, for Dorset.
1706. RHODUDENDIWN PONTICUM L. Mr W. B. Tun-ill gives
(Gard. Chron. :378 (1), 1921) an account of this popular species,
which is now so cOlllpletely naturalised in the warm sandy soils of
south-west Britain, where it seeds frequently. He says it occurs
in the south-western Caucasus (Colchis or Pontic region) frOll! the
sea-coast to 1800 metres, hence its specific name. Noe collecie(l it un
the Bithynian Olympus, ",yhere I failed t() find it in the spring. It
',Isu occurs in Azerbaijan and in the Lebanon from 1000 to 2000 m.
as a form called brachycarpwn. There is another widely separated
area in the south of the province of Cadiz, in N. W. Portugal, and in
Northern Portugal, Beira, etc. The evidence of Rhododen(ln)l1 remains
in the Tertiary beds is discussed. The Hottinger breccia near
Innsbruck yields plant-remains which were described by Wettstein,
antI in the Isle of Skyros in the Aegean Sea leaves have been discovered
in tufa of a Quaternary age, Our honal'ary member, Professor
Domin, has (lescribed a variety 81wrpil'ii, differing from the
type in having long persistent flower-bracts, from oakwoods at MalbJ
Tirnovo at 400 metres, just on the Bulgarian side .of the Thracian
frontier,
