Before being ordained Smith published his major botanical work, A Catalogue of rare or remarkable Phanogamous Plants collected in South Kent, London, 1829, which is dated from Sandgate. The Catalogue, of 76 pages, is arranged by the Linnæan system, deals critically with several groups, and had coloured plates drawn by the author.[1]
Smith was the first to recognise several British plants, describing Statice occidentalis under the name S. binervosa in the Supplement to English Botany (1831, p. 63), and Filago apiculata in The Phytologist for 1846 (p. 575). He contributed Remarks on Ophrys to John Claudius Loudon's Magazine of Natural History in 1828 (i. 398); On the Claims of Alyssum calycinum to a place in the British Flora to The Phytologist for 1845 (ii. 232); a preface to W. E. Howe's Ferns of Derbyshire in 1861, enlarged in the edition of 1877; and Notes on the Flora of Derbyshire to the Journal of Botany, British and Foreign for 1881. Other works were:[1]
