206 NOTES RESPECTING SOME PLYMOUTH PLANTS. 
thence to Mothecombe. Pyrus communis, L., occurs in the same hedge, 
and I suspect that both it and the Mespilus were originally planted at 
Battisborough. 
ysospermum Cornubiense, De Cand. Scattered all over, and abun- 
dant in some parts of a piece of uncultivated ground, rather more than 
an acre in extent (according to a rough calculation), situated between 
Inchers and Blaxton, on the brow of the hill above the right bank of 
the tributary of the Tavy, that flows down to the latter place. From 
Calstock, in Cornwall, the nearest recorded station of the Physosper- 
mum, this one is distant, in a straight line about five or six miles, and 
from New Bridge, near Tavistock, its only previously known South 
Devon one, seven or eight. It is probable that cultivation has re- 
stricted its range between Blaxton and Inchers, as some of the spots 
in which it most abounds are close to where marks of the ploughshare 
are visible, and at present (June, 1868) a field of corn adjoins its 
habitat, without any hedge or fence between. Among the plants 
associated with the Physospermum are Aquilegia vulgaris, L.; Viola 
canina, L.; B. lancifolia, Thore (Bab. Man. ed. 6); Potentilla Tor- 
mentilla, Nesl.; Galium saxatile, L. ; Serratula tinctoria, L. ; and Erica 
cinerea, L. ; ipd here and there are bushes of Rhamnus Diipa, L., 
and Quercus Robur, L. A damp pasture, not much above the sea-level, 
situated lower down the vale, produces a plant, Alchemilla vulgaris, L., 
rare in the neighbourhood; a bank near it yields Erodium moschatum, 
Sm., and Geranium rotundifolium, L., occurs. 
Lamium incisum, Willd. Very uncommon near Plymouth. In 
arable land at Prospect, Weston Peverell, March, 1868. Noticed at 
the same place in the spring of the previous year, associated, on both 
occasions, with Lamium amplexicaule, L., a species that is local in this 
part of Devon. 
Primula vulgaris, Huds., B. variabilis (Bab. Man. ed. 6), P. ofici- 
nali-vulgaris, Syme, Eng. Bot. ed. 3. Many specimens of this hybrid 
grow on hedgebanks about Maristowe, one of the localities near 
Plymouth, where Primula veris, L., occurs in most abundance. Farm- . 
ing operations have there, to some iate restrieted the latter to banks 
and the borders of fields, and it is on hedgebanks where P. vulgaris 
and P. veris are brought into proximity to each other, that the hybrid 
usually grows. Some examples most resemble one parent, others t 
other; but all have at least some of the flowers raised on a scape,
