Encloses specimens of 'Hieracium', which are "truly intricate like the willows and some other families", believes no one can judge of between species and varities unless they cultivate them; numbered observations: 1. 'Hieracium ramosum' said to be native of Hungary; 2. 'H. kalmii', contrary to Goodenough's claim distinct from 'H. prenanthoides'; 3. a 'Hieracium' he previoulsy thought described in "Flora Britannica". Asks Goodenough to forward this letter to Dr [James Edward] Smith.

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].

Constantly reminded of Smith by his "very assiduous & ever-to-be-encouraged correspondent Mr G[eorge] Don". Made to doubt his own knowledge after seeing Don's "acute observations", and wonder "where have all these things lain since the days of Adam, that no one should have noticed them before". Does not wish for Smith to be charged for any of [the Don letters and plant specimens]. Eagerly awaiting confirmation of Smith's visit.

Discusses etymology of 'Ethulia', 'Euclea', and Linnaeus' non-scholarly formation of names. Fears death of Lady Amelia Hume will remove Sir Abraham Hume from natural history. Continually asked when the fourth volume of "Flora Britannica" is out. Had told a group of country botanists in Carlisle region that Smith was coming to visit, they shall be disappointed. If Smith visits next year requests root of Smith's "pale primrose-coloured Carnation".
