232 Mr Evans, Notes on additions to the 
Vinca minor 4. 
Blackstonia perfoliata 4. 
Myosotis collina var. Mittenii (Baker) 6 (Moss). 
Lycium barbarum L. and L. chinense (Mill), both occur, not 
uncommonly, in the county. 
Bartsia verna 5. 
Bartsia serotina 1, 5, ete. 
Pedicularis sylvatica. In some quantity at Gamlingay in 1912 
(Evans). ; 
Prunella vulgaris x laciniata 5 (Hardwick, Moss). 
P. laciniata 5 (Hardwick, A. W. Graveson). 
Lanium hybridum 6. 
Atriplex patula var. erecta. Babington’s plant is merely a 
variety of patula and not the plant of Hudson or Smith. 
Polygonum aviculare. This aggregate must now stand as follows 
for the county : 
P. aviculare L. (=P. heterophyllum Lindman) 1, 5, ete. 
P. ruriwwagum Boreau 3. 
P. cequale Lindman 1, 5, ete. 
P. maculatum 4. 
Ulmus procera Salisb. must stand as U. nitens Mcench., the 
former proves to be a synonym of U. campestris L. 
Myrica gale. In quantity at a new station in Wicken Fen 
(Evans). 
Alnus glutinosa Gaertn. 
var. typica Moss (the common form of southern England). 
var. macrocarpa (Loudon) 1 (Chippenham Fen, Moss). 
Quercus sessiliflora 5 (Gamlingay Wood, Adamson). 
Salia alba x pentandra 1 (Moss). 
Salia cinerea x viminalis 1 (Moss). 
Populus canadensis. Our common tree should stand as x P. 
serotina. It is always male, and always planted; x P. canadensis 
is rare in gardens near Cambridge, though “subwild” in Suffolk ; 
it is always female. 
LInparis Loeselit. The specimen mentioned in our former list 
as from Gamlingay has no doubt been accidentally transferred 
from one sheet of the Power Herbarium at Reigate to another: 
for a similar case has occurred with a specimen of Malaais 
paludosa labelled Burwell Fen, where the same explanation may 
be given. In other words the specimens have probably been 
interchanged. 
Orchis maculata var. O’Kellyi, Sawston Fen (Moss). 
Habenaria (Gymnadenia) Wahlenbergi, Sawston Fen (Moss). 
H. (G.) densiflora, Dernford Fen (Bab. Herbarium, fide Moss). 
Iris fetidissima. Several plants at Pampisford (Evans). 
Juncus bufonius var. fasciculatus 1 (Upware, Adamson). 
i These must replace B. Odontites.
