Journal of Proceedings. xlv part of the ancient Forest of Essex, Hard by was a meadow locality for adder's-tongue (Ophioglossum) and Orchis Morio, known well to Mr. English, round the borders of which some splendid plants of Equisetum were growing. Returning to the Forest, we crossed a bog where the white-rot (Hydrocotyle vulgare) abundantly illustrated a departure from the normal foliage of umbelliferous plants, and here a few species of Fungi were noted. Russula vesca, with its rosy pileus; Marasmius urens, a poisonous species with a very pungent odour ; Agaricus fuscipes and A. appendiculatus—common, but welcome when other forms are not to be found. Here also we met with Stereum purpureum, an unusual sight at this season of year; usually the plant is only found in perfection during the winter time. Passing onward through a rushy swamp, which in spring is always gay with flowers, notably Caltha palustris, we cross the new road to Gayne's Park and enter the fields known as the "Lawns," where in days gone by Mr. English tells us the larva of the burnet moth (Zygaena filipendula) used to swarm, and where at early morn the vagrant cuckoos could be seen feasting on the unsuspecting caterpillars. From the "Lawns" we enter the fine woods, which, although contiguous, are known by the several names of Gaynes Park Woods or "Birchen Copse," Hawk's Hill and Ongar Park Woods. Having previously noted Bartsia eu-Odontites and the yellow rattle (Rhinanthus crista-galli), we now come upon a third of the semi-parasitic Scrophulariads, the cow-wheat (Melampyrum pratense) ; and in a ditch, then dry, near the site of the "Centre-tree" (now a thing of the past, but the seven rides or "wonts" converging still mark the spot), was abundance of the skull-cap (Scutellaris galericulata), with the wood pimpernel and the money-wort (Lysimachia nemorum and Nummularia). Here Mr. English, from a well- remembered spot, obtained abundance of the rose-bay (Epilobium angustifolium), E. hirsutum, E, palustre, and E. obscurum being also noted during the day; whilst their graceful ally, the enchanter's night- shade (Cireaea lutetiana) was abundant. On the trunks of the oaks we noticed many specimens of the fine moth, the "black arches" (Liparis monacha), and one or two of Epunda viminalis; whilst among the butterflies the fresh Gonepteryx Rhamni, some Vanessidae, "gate-keepers," "blues," and "skippers" were welcomed as very old friends. The alders yielded many specimens of a remarkable stalked gall on the upper side of the leaves, the work of one of the Phytopi or gall-mites (perhaps Cephaloneum pustulatum, Bremi.); and on the maples were thousands of the reddish leaf-galls of another mite (Cephaloneum myriadeum), and the wild roses bore "bedeguars" in abundance. Taking the Epping ride, one of the seven, we descended the hill, noting the fungus Lactarius piperatus on the banks, regained the Coopersale Forest, and then made for the gravel-pits. Here Hottonia palustris, we were told, had once been common, but had apparently been exterminated by the gravel-digging. But we found a nice Sphagnum bog, containing abundance of a plant somewhat rare in South Essex,—Menyanthes trifoliata,—the eathery
