THE ESSEX NATURALIST
Other uncommon species which were seen near here include:
Phascum curvicollum Hedw., Pottia recta (Sm.) Mitt., Barbula
revoluta Brid., Scleropodium illicebrum (Hedw.) B. & S., and
Rhynchostegiella pallidirostra (A. Br.) Loeske with capsules, all
these from Audley End. Encalypta vulgaris Hedw., from railway
embankment at Littlebury, Pottia lanceolata (Hedw.) C.M., from
chalk near Chrishall Church, and the liverwort, Sphaerocarpos
michelii Bellardi from stubble field near Peyton Hall.
Further south in the gravel pit regions around Fishers Green
at Waltham Abbey some well established colonies of Bryum
pallens (Brid.) Rohl, Bryum affine (Bruch.) F. Schultz, and Bryum
pseudotriquetrum (Hedw.) Schwaegr, var. bimum (Brid.) Richards
& Wallace were seen, all these occurring on both sides of the
boundary between Essex (v.c. 19) and Hertfordshire (v.c. 20), the
boundary here being the course of the old River Lea.
Another interesting record was the finding at Epping Long
Green of Fontinalis antipyretica Hedw. with capsules. This is
uncommon and apparently occurs after a dry summer when the
plant is no longer submerged in water.
It is also of interest to note that during 1959 Dr. H. L. K.
Whitehouse of Cambridge made an examination of the collection,
dated, 1874, of F. Y. Brocas in the Saffron Walden herbarium
and due to some errors of identification several species have been
added to the Essex list and a few have been deleted.
