Has sent Smith the requested specimens of 'Clara' from Bolart's herbarium, which is rapidly decaying. Eager to see [William] Sole's mints ['Mentha'], at present cannot follow his descriptions and would be pleased to see some of his plants reduced "to a more subordinate rank than that of species". Discussion of 'Campanula': considers a variety of 'Campanula rotundifolia' in Oxford Botanic Garden to be 'Campanula rhomboidea' on account of leaves; asks Smith's familiarity with 'Campanula mollis', named by [John] Sibthorp 'C. rupestris'. Received roots of 'Eriocaulon' from northern England, unsure what trivial name to give the species. [James] Sowerby's 'Polygonum bistortum'. Grateful to Smith for gathering the 'Statice' of the Norfolk coast. Requests seeds of 'Melampyrum cristatum' and others, and specimens of new 'Orobanche' except 'Orobanche elatior'.
