One of the key publications regarding the London Clay Flora which are located at the shores at Sheppey. This publication functions as the second part of the Catalogue of Cenozoic Plants in the Department of Geology at the British Museum of Natural History. Before the publication of this work the London Clay Flora had not been the subject of a published work since Bowerbank's work a century earlier. Compared to Bowerbank's book, Reid and Chandler's publication focuses less on the general description of the fossil fruits and seeds at the shores and more on the conditions that allowed the fossils to occur. Although there is a descriptive section in the publication where Reid and Chandler engage in systematic descriptions of thallophyta, charophyta, cymnospermae, monocotyledones, and dicotyledones, the main importance of this publication lies in the conclusion the authors present regarding flora, the climate of the London Clay flora, and relations between fossils and floras.
