THE HEPATICS OF ESSEX.

as Dumbarton and as far east as S. Aberdeen. During recent
Cryptogamic Forays of the Essex Field Club, this species has
been observed in several stations in Epping Forest. Another
species, Ricciocarpus natans, found in a pond near Chigwell,
in 1917, still grows in that pond, and also, as noted by Mr.
D. J. Scourfield, F.Z.S., in a pond near by. During the last
two years, Riccia commutata, R. sorocarpa, and Lophozia
turbinata have been added to the county list, and numerous
additions have been made to V.C. 19 by Mr. J. Ross, Miss E.
Armitage and other workers. Mr. H. H. Knight, M.A., kindly
forwarded me a specimen of Cephaloziella Hampeana collected
by A. Brinkman, in Epping Forest, in 1907.
For the compilation of the following list only a few works
were available, but many of the older records have been obtained
from an examination of the Hepatics in the Herbarium of the
British Museum, with the kind assistance of Mr. A. Gepp. This
Herbarium contains numerous specimens collected in Essex by
Edward Forster, 1765-1849, who studied cryptogams chiefly
in the Epping district. Other records have been gleaned from
"The Cryptogamic Flora of Kelvedon and its Neighbourhood ;
compiled from the Herbarium and Notes made by the late
E. G. Varenne, M.R.C.S."—by E. D. Marquand. This work
was published in the Essex Naturalist, Vol. V., Nos. 1—4,
1891. It contains a list of twenty-two species, identical with
that published in the "Victoria History of Essex," in 1903.
Numerous reports of the Essex Field Club dealing with the
Cryptogamic flora of Essex have also been consulted, together
with a typed list of Essex Bryophytes by W. R. Sherrin, A.L.S.
Records have also been obtained from the Census Catalogue
of Hepatics issued by the British Bryological Society, 1913,
but unfortunately in this case no localities were available.
