Sends specimens of a local species of 'Lotus' that is not the 'Lotus angustissimus' of Bauhin or Linnaeus, and has blossoms resembling 'Medicago polymorpha arabica'. Detailed description and habitat information. From long observation concludes that two distinct species are included under 'Lotus corniculatus', suggests 'Lotus gibbus' and 'Lotus patulus' and gives detailed description and habitat information of each. Detailed description and habitat of local 'Rubia' and 'Melittis melissophyllum'. 'Brassica monensis' of [Dillenius'] "Hortus Elthamensis" grows abundantly, Lightfoot's plant resembles 'Erica monensis' in "Herbal" of Bobart or Merison at Oxford and believes it to be a different plant, in a detailed description remarks that the leaves resemble 'Sisymbrium nasturtium'. Praises Smith and "English Botany". Remarks that he has found 'Euphorbia lathyris' twice in a "truly wild state". On the last page 'Lotus diffusus' is noted, possibly in Smith's hand.

Confesses to an error he made in his last letter to Smith regarding 'Sisymbrium monense', which he now supposes to be the variety of 'Erysimum barbarea' Smith refers to in "English Botany" and now has two seedlings of it growing, description of characteristics, differing "very considerably from the American Cress". Having compared prints of 'Melittis grandiflora' and 'Melittis melissopyllum' from "English Botany" concludes that he has never found the latter plant. The 'Lotus' he sent Smith has since been sent to the Oxford Botanic Garden by [James] Dickson. Notes a habitat for 'Convolvulus sepium'. Description and habitat for 'Verbascum blattaria'. Habitat for the 'Inula miginosa' of [John] Sibthorp, suggests [William] Withering's suggsted name of 'cylindrica' is improper, as is Sibthorp's. Glad to hear that Smith is undertaking publication of "Flora Graeca".

Sending four specimens of 'Trifolium', which he thinks misunderstood by English botanists; presumes they are 'T. procumbens', 'T. filiforme', 'T. agarium', and 'T. spadiceum', discusses each in detail.
