Sending specimens of 'Conferva', of which [James] Sowerby has made drawings. Observations on 'Conferva corallina' and 'C. retacea'; tried to make a genus from them.

Numbered descriptions of 6 of the specimens, some has identified 'C. multifida' Hudson and 'C. pedicellata'.

Sending this letter and enclosed specimens via [James] Sowerby, contains 'Grimmia nigritia', 'G. inclanata', 'G. schisti', 'Bryum gulaium' and 'Bartramia alpina'. Also encloses mosses, a 'Lichen', and a grass found in the white mine near Forfar [Smith annotation: "'Aira caespitosa'"] in 1807. Intends to undertake botanical excursion to the Cairngorns and Clova Mountains soon, but is unsure whether to collect for Sowerby, having heard nothing from him about previous specimens. Requests seeds of 'Felia muscosa' and 'Limosella aquatica'. Requests Smith's opinion on these and previous specimens.

Sending letter and "clever" drawings from Dr [Charles] Campbell, who is travelling to Sumatra; understands that knowledge of Sumatran botany would be extremely interesting to European botanists. Campbell was unable to provide description of 'Marsdenia'. If the East India Company establishes a Botanic Garden on St Helena hopes seeds from Sumatra will be naturalised here.
