                                Plate 19 figures B-E from the paper “An account of a new species of the Bark-tree, found in the Island of St Lucia”, by George Davidson, Philosophical Transactions of the Royal Society, vol.74 part 2 (1784), pp.452-456. Botanical studies of parts of a tree from the West Indies used as an anti-malarial treatment.  Several details were taken from this original work to form part of the published plate, notably the seed vessels, and details of magnified seeds. However the main works, a sprig from the tree with unopened seed pods and a study of the leaf were not reproduced. A key to the illustration, headed “Plate IInd” appears in ink verso:  “A. “Capsula bilocularis...B. Semen alatum magnificutum...C. Folia oblonga. Districha. D. Cyma. E. Seminis magnitude vera.” Not signed.
