THE FLORA OF WANSTEAD PARK DISTRICT. 123
Shoulder of Mutton Pond, are probably descendants of those
planted by Sir Josiah Child. The thickets of Rhododendron
mark the time when that part of the Park was laid out as "a
shrubbery," traversed by the winding paths shown in Rocque's
map. Although much of the old formality has gone it is probable
that the grounds with their tall Oaks, Ashes, Elms and Horse-
chestnuts are as beautiful now as they have ever been.
W. The Warren Estate.
This lies between Wanstead Park proper, and the old Wanstead
House Stables, now the Golf Pavilion. It is over an acre in
extent, and was made accessible to the public in 1938 when the
Warren mansion was demolished and the grounds became
building property. A winding cemented roadway was made
through its lawns and gardens to accommodate future dwelling
plots. One of the most striking trees here is a well-grown
Chinese "Tree of Heaven," Ailanthus glandulosa (height 52 feet,
girth 6 feet 2 inches) ; some branches bore abundant fruit in 1940
amongst the handsome pinnate leaves ; many suckers were
springing from the roots : unfortunately the bark of the trunk
has been injured by partial ringing. Near it, half hidden by a
thicket of rhododendrons is a tree of the Japanese. Malus torin-
goides Hughes (10 feet high), a native of Western China intro-
duced in 1904, whose long-stalked red cherry-like fruits are
conspicuous when ripe. A slender Maidenhair-tree, Ginkgo
biloba (height 13 feet) grows near some fine Elms. These last
may be a hundred years old or more, and are certainly older
than the date of Warren House. Besides Ulmus campestris Sm.
(syn. U. procera) and 17. montana Smith (syn. U. glabra Hud.)
Wych Elm, my friend Mr. A. Bruce Jackson has identified in the
Warren grounds U. Hollandica Miller, the Dutch Elm (for des-
cription see Steps' Trees in Wayside and Woodland series, latest
edition). He also recognized there a form nearly allied to the
Dutch Elm, and with smaller leaves, but frequent changes in
nomenclature of our English Elms make the subject too compli-
cated to deal with satisfactorily here. Among the Conifers of the
old garden are a Deodar, several Corsican Pines, an Austrian
Pine, a number of Scots Pines and yews, of which the largest
must have been a noble tree, but it has been badly cut back and
disfigured (height 55 feet, girth 9 feet 6 inches).
