NOTES RESPECTING SOME PLYMOUTH PLANTS. 319
to this plant by Mr. Kemptliorne, of Callington, wlio found it growing
in a field near Newton Ferrers. On grassy knolls among the heath
and furze of Vernico, the Phi/sospermum is particularly plentiful." I
have, to some extent, verified the above statement during the past
sumnaer, for, within the tract of country indicated, I have found it in
abundance in woods by a tributary of the Lynher, near Pillaton, and
also quite common in many spots near Clapper Bridge. It has, more-
over, a wider range than the writer above quoted gives it, for it is
plentiful in spots on and about Hammet and Hayfield Downs, between
Newton Fen'ers and Quethiock.
Galium verum, L. ; iS. ochroleucum, Syme, Eng. Bot. ed. 3 ; Lond.
Cat. ed. 6.— A. patch of this occurs on a cliff near Lugger's Cave,
above Whitsand Bay, Eame, Cornwall. Plants of both Galium vei'um,
a. luteum, Syme, and Galium Mollugo, L., grow near it.
Valerianella Auricula, De Cand.—In a cornfield between Quethiock
and Hammel Down, Cornwall ; growing with V. dentaia, Koch,
July, 1869.
LysimacJiia vulgaris, L.—Near Plymouth I have seen this species
only in the valley of the Lynher, and there but sparingly. It occurs,
however, many miles further west, near Probus, Cornwall, where I
gathered it recently.
Centunculus minimus, L.—From its small size this is often over-
looked, and so is probably a commoner species than many suppose.
During last July and August I found it at the six following localities,
all within twelve miles of Plymouth, but at none of which, so far as I
am aware, had any one noticed it before. In a damp spot, on Crown-
hill Down, near Newnham Park, growing plentifully with Radiola Mil-
legrana, Sw., a species it is very commonly associated with ; in two or
three spots (abundant in one) in a bushy meadow between Bickleigh
and Roborough Down ; in two others in the vale of the Plym, between
Meavy and Hoo Meavj' ; these localities are in Devon. On Yiverdon
and Pillaton Downs, and iji a vale by a tributarj' of the Lynher, over
which passes the road from S. MeUion to Pillaton village, Cornwall.
At the last station it was in August last plentiful by the cart-track in
the vale, a few gunshots above the bridge.
Littorella lacuslris, L.— In and about two ponds near the " China
Clay Works," on Crownhill Down, near Plympton. In the neigh-
bourhood of Plymouth the Littorella is a very rare plant.
