SOUTH ESSEX BRAMBLES.
By C. E. BRITTON.
DURING the latter part of the summer of 1903, I visited
Warley Common and neighbourhood on two occasions
for the purpose of collecting and observing brambles, and paid
one similar visit to Danbury Common. Examples of all the
various kinds of brambles gathered on these occasions, were
included in the very large packet of Rubus specimens, which
I sent during the autumn to the Rev. W. Moyle Rogers, F.L.S.
for examination. I am very much indebted to him for his great
kindness in confirming my suggested names for some, and in
furnishing names for others that were beyond me, and I am
further indebted to him for the information that the following
species and varieties of Rubus are "new records" for the
Watsonian Vice-county, 18 South Essex:—Rubus nitidus
Wh. and N. ; R. imbricatus, Hort var. londinensis Rogers;
R. carpinifolius, Wh. and N.; R. dumnoniensis, Bab.;
R. pubescens Weihe, var. subinermis, Rogers; R. angli-
canus, Rogers; R. fuscus, Wh. and N. var. nutans, Rogers;
R. adornatus, P. J. Muell; R. dumetorum, Wh. and N.
var. britannicus (Rogers); R. balfourianus, Blox.
In the following lists an asterisk denotes that a dried
specimen of the plant in question from the locality mentioned
has been seen by Mr. Rogers.
Warley Common: Rubus idoeus, L., R. lindleianus,* Lees;
R. rhamnifolius Wh. & N.; R. pulcherrimus,* Neum.;
R. selmeri Lindeb.; R. rusticanus Merc.; R. pubescens
Weihe var. subinermis* Rogers (also at Childerditch*); R.
sprengelii* Weihe. Besides the usual pink-flowered form of
this, there also occurs at Warley Common, a form* with white
flowers which Mr. Rogers notes is a rare one. R. pyramidalis*
Kalt.; R. leucostachys Schleich.; R. anglicanus*
Rogers; ("a form one step towards type R. radula Weihe,"
Rogers); R. fuscus Wh. and N. var. nutans* Rogers; R.
foliosus* Wh. and N.; R. infecundus* Rogers (also at
Great Warley Street*); R. dumetorum, Wh. and N.;
R. balfourianus,* Blox.
On Tylers Common very few kinds of brambles grow. Rubus
rusticanus Merc. and R. dumetorum Wh. and N. are plentiful,
