31 the Purple Moor Grass (Molinia caerulea), the Tufted Hair Grass (Deschampsia cespitosa), the Wavy Hair grass (Deschampsia flexuosa) and Heath Grass (Danthonia decumbens). The structure of grasses was compared with that of the triangular stemmed sedges, e.g. the Green-ribbed Sedge (Carex binervis) and that of the hairy leaved woodrushes, e.g. Many-headed Woodrush (Luzula multiflora) as well as the round stemmed rushes eg the Common Rush (Juncus conglomeratus) and the Sharp-flowered Rush (Juncus (acutiflorus) . The Common Cow Wheat (Melampyrum pratense) was a conspicuous member of the flora, but perhaps the most interesting find was a patch of Bitter Vetch (Lathyrus montanus) which is a very local plant in Essex. Some early fungi were in evidence and the Tawny Grisette (Amanita fulva) and the Blusher (Amanita rubescens) were identified. In the afternoon we changed the planned visit to Kingley Wood and went to Hadleigh Castle instead As we walked towards it we saw a field full of the pale yellow flowers of the Hairy Buttercup (Ranunculus sardous). The castle grounds provided little of interest, except for some Lesser Calamint (Calamintha nepeta) and some Fern Grass (Desmazeria rigida) on the walls.
