243 OUR FOREST TREES, AND HOW THEY SHOULD BE REPRESENTED IN THE FOREST MUSEUM. By PROF. G. S. BOULGER, F.L.S., F.G.S. (Vice-President). [Being Abstract of an Address delivered at the meeting at Chingford on October 31st, 1896.] FEW persons would imagine that we have about fifty distinct species of trees within our Forest limits. This is exclusive of such recent introductions as the Rhododendrons of Oak Hill Enclosure, and of dwarf shrubs such as Furze, Broom, or some of the smaller Willows. One hesitates a little as to the inclusion of Blackthorn and Dogwood ; and some species recorded in the past probably exist no longer, Yew and Juniper being, perhaps, the most prominent in the latter category. Our one existing Conifer, Pinus sylvestris, though the few examples at Fairmead are well known to all visitors, and though it is recorded as having been previously self-sown at Snaresbrook Pond has no claim to rank as indigenous. The Bird Cherry (Prunus padus) was recorded from near Epping by Doubleday, but I do not think it exists any longer ; and among species of the present occurrence of which I am in doubt are the Rowan (Pyrus aucuparia) and the Service (Pyrus torminalis.) The Small-leaved Linden (Tilia parvifolia) is almost certainly wild in the county, if not within the Forest area, though other species have been planted. The Maple (Acer campestre), the beautifully-fruited Spindle-tree (Euonymus europaeus), the Wayfaring-tree (Viburnum lantana), and the Guelder-rose (V. opulus) are not common, if the two latter even occur. The Hazel (Corylus avellana) is almost confined to Epping Thicks, and the Alder (Alnus glutinosa) to the banks of the Ching, though outside the Forest both these species are fairly common. Dull-Boy Slade still rejoices in one Pear (Pyrus com- munis), and anyone who has not seen our Forest Crab-apples (Pyrus maius)—originally preserved on account of the deer—when in flower, should take the first opportunity of doing so. There are two sub-species of this tree and two also of the Hawthorn (Crataegus oxyacantha) represented in our area. The Oaks are represented by
