Believes the specimens of [William] Hudson's 'Mentha villosa' he received from [Samuel] Goodenough are 'Mentha sylvestris', confirmed by Linnaeus and Ray in "Historiae plantarum"; further observations on it. Received 'Mentha sativa' from Bath from Goodenough, who believes Pitchford's garden 'M. satvia' is 'M. gentilis'. Confusion over figures of 'M. sylvestris' and other 'Mentha' species in "the old authors" Hudson, [John] Gerard [(1545-1612)], [John] Ray, and [John] Parkinson [(1567-1650)]. Has thirteen customers for [James] Sowerby's work [presumably "English Botany"], and one for [James] Dickson's "Plan[tarum] Crypt[ogamicarum]". Dickson sent him '[Acrostichum] ilvense', thinks it different from the Swedish specimen. Will consult [William] Sole on 'Mentha'. Received 'Sium repens' from Dr Randolph of Oxford, found by [John] Sibthorp, new to England, asks if it is also a new Linnaean one.

Returns Smith's 'Mentha gentilis', believes it the plant of Linnaeus and wild although [Edmund] Davall not as as specific as he would wish, makes his own observations including reference to [John] Ray's "Hist[oriae plantarum]", only needs to see [Philip] Miller's 'M. gentilis' and 'M. sativa' specimens to complete his work. Observations on the 'M. corolla', believes it will help distinguish most species. Observations on Smith's notes of the different specimens: 'M. arvensis', 'M. sativa', 'M. sylvestris', 'M. rotundifolia', 'Menthiastic aquatici'; hopes [Samuel] Goodenough has conceded that his 'Mentha villosa' is 'M. sylvestris'; further observations on these in postscript. Explains errors is Fuschius' figures. Thanks Smith for specimen of 'Schoenus ferrugineus'. Miller's 'Mentha gentilis'.
