Vol. XXVII—Part XII. Oct., 1945—March, 1946. THE Essex Naturalist: BEING THE Journal of the Essex Field Club. ADDITIONS TO THE LIST OF FLOWERING PLANTS FOUND IN THE BUSHWOOD AREA OF THE WANSTEAD PARK DISTRICT SINCE 1941.1 By O. LISTER, F.L.S. [Read October 27th, 1945.] DURING the years of the War, from 1941 to early in 1945, the northern open part of Bushwood underwent considerable changes. A large area was wired off from the public for the use of a tethered balloon and its staff : the resulting traffic has led to the introduction of a number of plants foreign to the Forest. Another source of the appearance of non-forest plants was the formation of an extensive and much-used underground shelter near the junction of Bush Road and Blake Hall Road : this was closed in the spring of 1945. In this section of Bushwood the following plants were not recorded in the former list. An asterisk * indicates a cultivated garden plant. Ranunculaceae. Ranunculus acris L. ; Meadow Buttercup. Several plants. R. repens is still abundant in some parts. FUMARIACEAE. Fumaria officinalis L. ; Fumitory. A single plant on waste ground. Caryophyllacea. Spergularia rubra Preslin ; Red Sandwort. A single plant. Malvacea. Malva sylvestris L. ; Common Mallow. One colony on waste ground. M. rotundifolia L. ; Dwarf Mallow. A large plant on waste ground. 1 See The Flora of Wanstead Park District.
