Encloses specimen of true 'Hieracium prenanthoides'. Numbered observations on additional enclosed specimens: 1. an unknown 'Hieracium'; 2. possible 'H. kalmii' raised from seed by Mr Mackay; 3. a 'Hieracium' grown by late [William] Curtis in his Lambeth garden, never found wild, raised from seeds sent by [James] Donn [(1758-1813), curator of Cambridge Botanic Garden] under names of 'H. cornatum' and another.

Numbered observations on enclosed specimens: 1. an 'Agrostis', discovered on beach in Angushire in 1807 with 'Equisetum variegatum' [Goodenough annotation: "can this be a variety of 'Agrostis setacea'? S.C."]; 2. a 'Saxifraga' same as no. 8 in letter he sent 3 April 1809; 3. a 'Scleranthus'; 4. a 'Scleranthus annuus'; 5. a new 'Anthemis' proposes name 'A. bicolor'; 6. another new 'Anthemis' proposes name 'A. tricolor'. Hopes to hear from Goodenough soon, asks him to forward this letter to Dr [James Edward] Smith [address label to Smith at Norwich, 3 September 1809].

Responds to queries in Smith's letter of 8 September [1809]: will send 'Lamium' seeds; has found no evidence of 'Lychnis alpina' being planted, despite rarity, difficulty of ascertaining how many seeds it proudces, describes similar instances with 'Gentiana nivale', 'Gnaphalium sylvaticum', 'Sonchus caeruleus', and 'Hieracium molle'.

Numbered remarks and observations on plants, headed 18 May [probably date of Smith's reply to Don's letter of 3 April 1809]: 1. will try to identify the 'Ranunculus'; 2. 'Saxifraga' new species; 3. 'Potentilla' new species; 4. 'Grimmia' new species. Obervations on 'Ranunculus alpestres'; 'Crepis pulchra'; species of 'Silene'; 'Cochlearia groenlandica'. Observations on numbered specimens in his last letter: 8. argues case for naming new 'Saxifraga' 'S. peduncularis'; 9. "certainly not 'Stellaria cerastoides' but a 'Cerastium'.

Will send seeds of 'Spergula maxima'.

Sending specimens of 'Arundo neglecta', 'Rottboellia filiformis', very rare, 'Silene alpestre', and non-descript 'Poa'; observations. Observes what Goodenough says about 'Viola', there seem to be 3 species under name 'V. canina'. Does not think 'Arundo neglecta' can be what [John Leonard] Knapp has drawn for 'A. calamagrostis'; supposes he has received better 'Rubus' specimens from [Charles] Lyell.

Detailed observations on 'Avena', particularly 'A. pubescens' and a new glaucous one. Found new species of 'Aira' by the sea. Could not find 'Chaerophyllum'. Seeds for 'Galium witheringia' all gone for this year, but will collect seed next year as it is a common plant here. Sorry to disagree with Goodenough on the 'Gnaphalium'. Encloses seeds of two varities of 'Daucus mauritanicus'.

Desires Goodenough's opinion on remainder of the plants he sent via Lyell. Sent [James] Sowerby a 'Cochlearia', who thought it 'C. anglica', would like opinion on this and 'Potentilla tridentata', which grows amongst roots of 'Erica vulgaris'.

Numbered observations on enclosed specimens: 1. nondescript 'Poa', different from most other species including 'P. compressa'; 2. 'Asplenium alternifolium' from America; 3. an 'Agaricus' growing on 'Trichosotum lanuginosum'; 4-5. 'Biameages' [?]; 6. possible 'Lichen abietinus' of "English botany"; 7. 'Conferva' growing on decayed 'Agaricus'; 8. 'Conferva'; 9. [indecipherable, same as 4 and 5]; 10. 'Dicranum strumiferum'; 11. minute 'Grimmia'.

Long desiderata for his garden, to be sent by franks or ship from London to Dundee.
