Sending Smith a 'Chara' allied to 'Chara flexilis' found at Cley, Norfolk, previously sent to [James] Sowerby, and also sending the true 'Chara flexilis' for comparison. Desires Smith's opinion on whether they are distinct species, as he and [Dawson] Turner believe, and suggests amendment to Sowerby's drawing if so. Has found 'Salicornia radicans' and [William] Hooker has found 'Fucus amphibius', both at Cley.

'Lichen stellaris' and its affinities "very imperfectly understood" by English botanists: encloses specimens [not extant] and remarks [extant] on those occurring within this neighbourhood, except 'L. caesius' and 'L. aleurites', which are sufficiently known. Uncertain about his quotation of Acharius; necessity for a work on the subject according to [Dawson] Turner's recommendations in "Linnean Transactions" vol 7.

Notes written West Town, [near Lewes, Sussex], November 1804, on 8 lichens: 'Lichen cycloselis', 'L. ulothrex', 'L. virellus', 'L. pulverulentus', 'L. aipolius', 'L. anthelinus', 'L. stellaris', and a new 'Lichen'.

5 coloured drawings on 2 folios of several lichens, with pencil notes [by Smith] naming 'Lichen nigro-virens' found by Charles Lyell 1809 and 'Lichen pezizoides' found by Borrer. 8 partly coloured drawings on 2 folios of leaf, twig, and flower of 'Salix', with pencil notes [by Smith] detailing specimens found by Borrer in 1813 [unclear if drawings belong to this letter].
