12. of four. This latter plant is more often found on wet heaths, and scattered about the area were some other plants indicating wetter conditions e.g. the common rush (Juncus conglomeratus). Rushes can easily be distin- guished from grasses by their round stems filled with soft pith. Sedges always have triangular stems. The marsh thistle (Cirsium palustre) was also present here and there. This thistle, with its tall rather drawn out appearance, was outnumbered by its relatives, namely the creeping thistle (Cirsium arvense) and the much spinier spear thistle (Cirsium vulgare). Another plant of moist places was an occasional fleabane (Pulicaria dysenterica) which is also a member of the daisy family (Compositae) in which the "flowers" are really groups of many tiny true flowers or florets in a conspicuous inflorescence. Much more numerous was another composite called ragwort (Senecio jacobaea) which often provided nourishment for the caterpillars of the cinnabar moth with their black and orange bands. Some conspicuous plants in flower were the common centaury (Centaurium erythraea) which is a pink member of the gentian family (Gentianaceae) found here in the dry areas; the common St. John's Wort (Hypericum perforatum) which has yellow flowers, two raised lines on its stem and translucent dots on its leaves which you can see if you hold them up to the light; the common milkwort (Polygala vulgaris) with its small blue flowers more typical of heaths, as is the wood sage (Teucrium scorodonia) with its unspectacular yellowish green flowers. This is a member of a very easily recognised family of plants with its square stems and opposite leaves, namely the mint family (Labiatae). The pea family provided the yellow-red flowers of birdsfoot trefoil (Lotus corniculatus) also known as bacon and eggs, as well as the scrambling masses of the hairy tare (Vicia hirsuta) with tendrils, tiny blue flowers and hairy two-seeded pods. Amongst several other plants one of the most interesting
