Sends specimens for determination, to be returned: one is possibly the true 'Dianthus glaucus' and the other a 'Potamogeton'. Received letter from [Samuel] Goodenough in which he states 'Carex caespitosa' does not grow in England; disagrees, also mentions 'C. gracilis'. Encloses 'Jungermania asplenioides' gathered near Holy-well, Flintshire; observations, it may be 'viticulosa'.

Asks after particulars of Smith's projected new work ["Icones pictae plantarum"]; hopes he will not forget a "Flora Britannica", the need for one. Sending specimens for Linnean Society of 'Salsola fruticosa' and 'Carex caespitosa' "Fl[ora] Ang[lica]". Believes 'Sparganium natans' will turn out to be 'S. simplex' Fl Ang.

Thanks for specimens. Asks if [John] Lightfoot's annotated copy of [William] Hudson's "Flora Anglica" is still for sale at White's. [Thomas] Woodward agrees with him that his 'Carex caespitosa' is not 'C. gracilis' in a small state, as Smith and [Samuel] Goodenough think; observations. Sent Goodenough two specimens of a possible 'Galium isuliginosum'. Thanks for Smith's notes on 'Dianthus glaucus'; observations. Sending "smallest known" 'Potamogeton', possibly Hudson's 'P. setacea', and possible 'Lichen pertusus'.

Specimen label attached with note "'Mucor infusorius' Lee", no specimen extant.
