FIELD NOTES PLANTS Plant notes and records are compiled by T. A. Warren Davis, South Mullock, Haverfordwest, Pembs., Dyfed, from reports of B. S.B.I. County Recorders to whom records should preferably be sent. Any received by T.A. W.D. will be passed to the Recorder concerned. Plants are listed for each county in the order of Dandy, List of British Vascular Plants (1958), the number in that list preceding the name, so that names recently changed can be used without giving the former name. All records for 1976 unless otherwise stated. The County Recorders are:- T. G. Evans, La Cuesta, Mounton Road, Chepstow, Gwent. v.c. 35 MONMOUTH. G.

We were intrigued to discover that a clump of Spindle (Euonymus europaeus) bushes which I had first seen in 1972 was associated with a stand of Dog's Mercury (Mercurialis perennis). This contrasted with the dense masses of Great Wood-rush (Luzula sylvatica) dominating the woodland field layer all around. The anomaly was explained when, a casual prod into the banks of the path exposed a number of shells of the Native Oyster (Ostrea edulis). It appeared
