4 THE EXISTING FLOWERING PLANTS OF EPPING FOREST.
Erysimum cheiranthoides, Linn. Cultivated fields about
Walthamstow.
Senebiera didyma, Pers. Seen in 1887 and 1888 near Hale
End, but not since. This plant appears and disappears in a very
capricious fashion. The other Wart Cress (S. coronopus) is quite
common.
The Cruciferae are poorly represented in the Forest area.
Judging from former records, we have lost considerably in this
Order.
Saponaria officinalis, Linn. Lark's Wood, Chingford, but
probably the remains of former cultivation. I have ascertained that
more than half a century ago a cottage stood there, with its garden.
Traces of the brick-work are still visible.
Stellaria palustris, Ehrh. (S. glauca, With.) Occurs also in
Lark's Wood.
S. uliginosa, Murr. Not very uncommon.
Montia fontana, Linn. V. minor tolerably common ; V.
rivularis comparatively rare.
Hypericum elodes, Huds. In one or two of the northern
bogs.
Linum catharticum, Linn. So common elsewhere, seen only
in one spot near Monk's Wood.
Euonymus europaeus, Linn. About Walthamstow, Buck-
hurst Hill, Chigwell Lane, &c.
Rhamnus catharticus, Linn. In several places. On
"Ludgate Plain" it grows almost to the size of a tree.
R. frangula, Linn. Seen only in one station.
Genista tinctoria, Linn. Occurred in 1878 near the highest
part of the Forest; not seen there recently, but heard of in another
locality from a botanical friend.
Melilotus altissima, Thuill. (M. officinalis, Willd), M. alba,
Desr., and M. officinalis, Desr. (M. arvensis, Wallr). These have
been collected about Walthamstow; the last by my friend Mr, R.
Paulson.
Ornithopus perpusillus, Linn. Found in several places on
high sandy ground.
Prunus insititia, Linn. Near Fairmead.
The Rubi have been already recorded (Essex Naturalist,
vol. iii., p. 20, and vol. v., p. 189), so that nothing need be repeated
