12. day. Against these additions to the Essex list, we have to report the possible loss of the Purple Cow-wheat (Melampyrum arvense) which did not appear in any of its stations last year, and the probable extinction of the Mersea Pea (Tetragondolobus maritimus). Having last seen the plant growing in rough grass by a car-park near Empress Avenue in 1956, I paid a visit to the site during August. The Pea grows abundan- tly in a garden now established on the site and the owners have supplied seed to a number of botanists. I gather however that even the experts at Kew have been unable to raise any seedlings. Attempts to establish it on the tumulus in the centre of the island were just as unsuccessful. The local council attempted to fence off a patch on the greensward near the car-park some years ago but this subsequently died out. A solitary plant appeared in rough grass just west of Empress Avenue last year but this was destroyed when the grass was mown. Unfortunately the owners of the house on the corner of Empress Avenue moved out last Sep- tember. We should be grateful to them for keeping the Mersea Pea as the most plentiful "weed" in their garden. Let us hope that the new owners will also protect this beautiful plant so that one day some seed may germinate successfully in a rough grassy place nearby. ---oOo--- WANTED An artist to design the next cover of the Bulletin and to illustrate forthcoming articles.
