THE ESSEX NATURALIST: BEING THE Journal of the Essex Field Club VOLUME XXVI. THE WATER VIOLET IN EPPING FOREST. By GULIELMA LISTER, F.L.S. THE frontispiece to the present volume of the Essex Naturalist is a reproduction of a water-colour sketch by my sister, the late Isabella S. Lister. It represents a colony of the Water-Violet, Hottonia palustris, growing in one of the Epping Forest ponds, and was painted about 1890, in early summer, when the plant was in full flower. The pond is in Gilbert Slade, north of the Snaresbrook road, and is screened on one side by oaks and low hornbeams. It is one of a group of small gravel-pit ponds in most of which Hottonia flourished at that time ; throughout the year its rosettes of rich green pectinate foliage could be seen through the clear water, while in summer grew up the tall scapes bearing many whorls of pale mauve Primula-like flowers. A series of dry summers has led to the disappearance of the Water-Violet from these little ponds, which are now almost filled with the tall water grass, Glyceria aquatica, Reed-mace and rushes ; but further north in the Forest, Hottonia still thrives in many of its old haunts. In the early copies of Richard Warner's 'Plantae Wood- fordienses,' printed in 1771,1 no mention is made of the Water Violet: the edition published in 1784, the year after Warner's death, includes "Additions" to his list, by Thomas Furly Forster, of Walthamstow, one of three brothers well known for their interest in Botany"; amongst the "Additions" Hottonia is recorded as growing " in marshy ditches near Lea Bridge, and "Hilliers Quay" [where the Ferry Boat Inn now stands]; "in "many gravel pits near the Windmill on the Forest" [this stood near the Napier Arms, Woodford]. 1 I learn from Mr. Percy Thompson that a MS. copy of 'Plantae Woodfordienses' now in the possession of Wadham College Library, Oxford, contains a note by R. Warner recording Hottonia for his district. A
