-S', orieiitale, L. Eoaclside at How Capel, Hereford, where it 
has been established for several years, liev. A. Ley. 
Lysimachia ciliata. In sending a supply of this from the old 
station a.t Seberghani, in Cumberland, Ilev. E. Wood writes ; — 
“ I have known it there for at least sixty-five years. There is still 
a considerable patch.” 
Plantayo Timbali, Jord. Hay-field at Kelso, Eoxburghshire, A. 
Brotheeston ; and forage-field at Penzance (coll. W. Curnow). 
J. Ealfs. 
Amaranthus retroflexus. Waste ground at Eichmond, Surrey, 
G. Nicholson. 
ChenopocUum opulifoUum. Mud-heaps at Mortlake, Surrey, G. 
Nicholson. 
Urtica pilulifera. The lower branches of several vigorous 
plants growing on rubbish-heaps at Kew had the deeply serrated 
leaves of typical pilulifera, whilst the upper part of the plant 
showed the entire or subentire leaves of var. Dodartii, G. 
Nicholson. 
Polygonum alpestre, C. A. Meyer. On the Surrey side of the 
Thames, near Kew Bridge, where it was first gathered by Mr. 
Naylor in 1872, G. Nicholson. It is identical with P. coynatum, 
Meisn., and is common through Western Asia. 
Rumex. Dr. Trimen has kindly examined the critical forms of 
Rumex received this year, and reports on them as follows : — “ An 
interesting series of specimens is sent by Eev. Augustin Ley from 
the banks of the tidal river Wye at Tintern, collected at the end 
of July, 1878. This Dock-vegetation in Monmouthshire is appa- 
rently much the same as that of the tidal Thames. 
“ Riunex, form of conylomeratus, Murr.” This is a rather 
slender form with ascending branches, but scarcely var. Borreri. 
“ Rumex, hybrid. Tidal banks, Tintern.” These are various 
forms of R. prntensis (^crispus X obtusifolius). 
“ Rumex elonyatus, Gussone ? Muddy tidal banks, Tintern, 
30th July, 1878.” A fine series of large specimens of this ; quite 
the same as the Thames plant. Whatever may be its proper 
name, it cannot be separated as a species from R. crispus. In some 
of Mr. Ley’s specimens the petals are denticulate, as in P. crispus, 
and one has the lower leaves slightly crisped. There is a sugges- 
tion of R. Plydrolapathum about this river-side Dock, but I do not 
think it is a hybrid between that species and R. crispus. 
“ Rumex hybrid, pulcher x obtusifolius. Waste ground. West 
Head, East Cornwall, near the sea, 12th July, 1878.” ^Portions of 
a large plant. I agree in the naming, but have not seen 
English specimens of this intermediate before. R. obtusifolius pre- 
dominates. 
“ Rumex hybrids. Waste ground by the sea. West Head,” and 
“ Hedgerow near Millbrook, East Cornwall, 12th July.” These 
are R. pratensis more or less typical. “Field near Cawsand, E. 
Cornwall.” The same ; a curious form, close to R, crispus, and 
witli the tubercles almost entirely suppressed. 
There are now on record a number of intermediate and probably
