228 THE ESSEX NATURALIST. Sedum telephium. "in a field near Woodstreet & on the side of Angel lane betwn Leyton & Stratford, etc." Aegopodium podagraria. "in our garden in Hoe Street." A. Zannichellia palustris. "In a pond in Clay street opposite Mrs. Williams's in ponds & marsh ditches common." Apium graveolens. "In the Marshes near the Thames plentifully, but not to be found in the places mentioned by Warner," that is, about Woodford Bridge and on the Roding banks. Antirrhinum majus. "on a wall in Claystreet and elsewhere not uncommon." Asperula odorata. "never yet found by us within the limits. It is an Essex plant, as in Duelds (? Dudds) Wood, near Henham." Asplenium Ceterach [now Ceterach officinarum]. "This is not to be found on Dr. Wilkinson's wall, nor did he ever see it there but Mr. Warner inserted it, having as he thought formerly seen it there, on a tombstone in Woodford Church yard on the E. side of the chancel 1812." A. Aster tripolium. "on the Banks of the Thames." A. Hypericum elodes. "In gravelpits on the Forest near the road which leads from Honey lane to the Epping road, on bogs on the Forest beyond Loughton." Botanists will be thankful that Edward Forster did not give a too-close locality for this Forest rarity, which still occurs in the neighbourhoods mentioned. Atropa belladonna. "Found 13 May 1794. On the Forest between Warner's Gravelpit Pond & the two Brewers a suspicious place also near the end of the Buckstile Walk, 1801." Betula alba. It is an interesting proof of the extraordinary manner in which the Birch has invaded the Forest district within the last century (Warner describes it in 1771 as "not very common") to find Edward Forster re cording its occurrence in detail, thus, "Found in the woody part of the Forest not far from Hale End May 1794, in woods near Park hall Theydon Gernon plentifully & on the forest near Coopersale & Park hall, in Great Shrub- bush." His entries are in ink of varying degrees of blackness, and would appear to have been made at considerable intervals of time : it is clear that i n his experience the Birch, now so abundant in the northern half of the Forest as to be regarded as a nuisance to be kept down rather than encouraged, was of comparatively rare occur- rence. A. Campanula hederacea [now Wahlenbergia hederacea]. "On the Forest at the head of a long bog between the Kings Oak and the hedge beyond Highbeech very uncommon. It flowers July or August. & in a bog S.E. of the Kings Oak & other bogs thereabouts in Ambres Banks." The Ivy-leaved Campanula was evidently more widely distributed in the Forest in Forster's time than it is now. A. Campanula rapunculus, "near a new house beyond Romford Common where the ground had been lately thrown up rather a suspicious place."
