be a hybrid F. vesca x chiloensis. The facies of the plant are fairly well 
represented in the plate of F. diinietoruni^ Jord. in Jordan and 
Fourreau’s ‘ leones/ but F. dumetorum belongs to the group of F. 
collina which has the calyx upright and appressed to the succulent 
receptacle. In this plant they are reflexed, as in F. vesca. It differs 
from this latter plant by its much larger leaves, with more open teeth, 
of a distinctly papyraceous texture, and conspicuously paler on the 
under surface, while the upper is of a darker green. The long, coarser 
runners are different from any I have seen in normal F. vesca. The 
very much smaller flowers and the smaller receptacle distinguish it 
from F. chiloensis. It may be well to distinguish it provisionally as 
F. bercheriensis ? vesca x chiloensis. — G. C. Druce. “ The hairs 
on the scape are reflexed for certain, anyhow now ! whether so when 
fresh ? But the calyx looks like a form of chiloensis.^ ” — Ar. Bennett. 
This is not a hybrid as it fruits freely. The presence of runners does 
not separate it from vesca ; I have ordinary vesca with even longer 
runners than appear in this plant. It is thus mainly distinct by its 
habit and size, and by the colour and texture of the leaves. I have 
just the same plant from Rockheath, Sprowston, Norfolk, and 
Godaiming, Surrey. Cultivation alongside of type vesca would show 
if it possesses features justifying its taking position as a variety or 
species. — W. R. L. 
Potentilla inclinata, Vill. Walton-on-Thames Common, i6th 
June, 1894. Alien. — W. H. Beeby. 
P. procumbens x Tormentilla. Between Witley and Thursley, 
Surrey, loth July, 1894. — S. T. Dunn. Railway Cutting, Edge 
Green, Cheshire, 24th July, 1894. — A. H. AVolley Dod. Copses 
near Dunsfold, Surrey, 24th July, 1894.- E. S. Marshall. The two 
first are confirmed by Rev. E. S. Marshall, and on his own he writes: 
“ All these specimens are from one strong growing prostrate plant. 
The hybrid is not rare thereabouts, varying considerably.” 
P. replans x Tormentilla. Roadside near Ivybridge, S, Devon, 13th 
July, 1894. Fairly intermediate. Petals uniformly four, larger than 
in P. Tormentilla. I saw no species near except the two parents. — 
E. S. Marshall. Mr. Marshall sends the same from near Chidding- 
fold, Surrey, 24th July, 1894. 
Alche 7 nilla vulgaris, L. v. alpestris (Schmidt). Moffat, Dumfries, 
7th July, 1894. — E. F. Linton. Ditto var. filicaulis (Buser). 
Moffat, Dumfries, July, 1894. — W. R. Linton. A short account of 
the vulgaris group by Rev, E. F. Linton will be found in ‘ Annals of 
Scot. Nat. Hist.’, 1895, p. 47; and in the ‘Journal of Botany’ for 
1895, p. no. 
Rosa Robertsoni, Baker. Near Ham Common, Surrey, 23rd J une and 
7th July, 1894. Named for me by Mr. Rogers. — A. H. Wolley Dod. 
The view of Continental specialists ( M. Crepin and others) at the present 
time is that R. mvoluta Sm., is a hybrid whose parentage is R. 
pimpinellifolia, Linn., on the one hand, and R. tomentosa or R. canina, 
or perhaps R. ttiollis, R. rubiginosa, or R. inicrantha, on the other.
