THE ESSEX NATURALIST: BEING THE Journal of the Essex Field Club FOR 1891. THE CRYPTOGAMIC FLORA OF KELVEDON AND ITS NEIGHBOURHOOD, TOGETHER WITH A FEW COAST SPECIES; COMPILED FROM THE HERBARIUM AND NOTES MADE BY THE LATE E. G. VARENNE, M.R.C.S. By E. D. MARQUAND [Read February 28th, 1891]. THE following lists have been carefully compiled from the collec- tions, notes, and memoranda made during a period of over forty years by my valued friend, the late Mr. E. G. Varenne, surgeon, of Kelvedon, who died on the 22nd of April, 1887, at the age of seventy-five.1 As a contribution to the Cryptogamic Flora of the county of Essex, so far as at present known, these lists cannot fail to be of great interest and value, since they embody the labours of an acute botanist whose researches in this department of science have never yet been published. Although possessing a wide practical acquaintance with all sec- tions of plant life, it was as a lichenologist that Mr. Varenne excelled ; the lichens were to him especial favourites, and of these he had, by a lifetime of study, acquired a critical knowledge surpassed by very few British botanists. His last work was the compilation of the lichen list which follows, the introductory preface to which unhappily remains in too rudimentary a condition to be available for the pur- poses of this paper. 1 A short memoir of Mr. Varenne (with portrait) by Prof. Boulger, is printed in the present volume.—Ed.
