Interglacial plant remains from the Wolvercote Channel, Oxford

Abstract
Summary: The Wolvercote Channel contains deposits with a fauna indicative, first, of warm and then of temperate conditions. These are overlaid by a peaty layer containing plant remains, itself succeeded by deposits indicative of cold conditions. Clement Reid and Bell recorded 23 different flowering plants from the peaty layer. From material in the Oxford University Museum some of Raid's labelled specimens have been re-examined, and further material not labelled by him has now been identified. The newly identified plants include Atriplex cf. hastata Linnaeus, cf. Cardarmine pratensis Linnaeus, Draba cf. incana Linnaeus, Pastinaca sativa Linnaeus, Potamogeton cf. filiformis Persoon or pectinatus Linnaeus, P. cf. perfoliatus Linnaeus, Potentilla sp., Rumex cf. acetosa Linnaeus, cf. Saxifraga sp., and Festuca sp. The ranges and habitat preferences of these plants, together with the plants identified earlier by Reid and by Bell, support a tentative conclusion that the climate was cool temperate. What is more certain is that the landscape was, at least locally, incompletely covered with vegetation.
