In 1829, botany had much to prove. A prominent lecturer, John Lindley, noted that 'it has been very much the fashion of late years, in this country, to undervalue the importance of this science, and to consider it an amusement for ladies rather than an occupation for the serious thoughts of man'. In the three documents reissued here, Cambridge botany professor John Stevens Henslow (1796–1861) demonstrates the exacting standards of his course. The work contains an 1829 catalogue of British plants, the skeleton structure of sixteen lectures for 1833 and an 1851 list of potential examination questions. Students were expected to differentiate between 'an indefinite and a definite inflorescence', to recognise 'albuminous seeds', and describe 'nectariferous appendages'. With a strongly Linnaean approach to taxonomy, this collection offers researchers a window into the growth of academic botany prior to the revolution occasioned by Stevens' pupil, Charles Darwin.
