Invites Smith to come to Hillingdon, [Middlesex], tomorrow to meet a Polish Princess who would like to see her plants. Has a Jamaican plant grown from seed in flower that Grieg, her gardener, knows nothing of.

Encloses certificate nominating [Robert] Stone [(c 1751-1829), botanist] as FLS. [John] Pitchford claims 'Geranium pusillum' is Dillenius' and not Ray's, so Pitchford can consider an error in the plant or engraving as it is not the fault of "Pope Ray"; discusses his own work on 'Geranium' including comparison with Scopoli and [Albrecht von] Haller [(1708-1777)]; convinced old 'Geranium rotundifolium' is Haller and Scopoli's 'G. malvifolium', but the plant exists in herbarium as 'G. pusillum', suggests solution.

His broken collarbone healing well. Gathered 'Fillaea muscosa' for [James] Dickson and will find 'Carex strigosa', 'C. pulicaris', 'C. diocia', and 'Mentha villosa'. Asks Smith to purchase and send the Chinese jar he saw off of Broad Street when last in London, description.
