Account of his 3 month botanical trip in north Wales, from which he returned in October [1798]: travelled on foot; unable to meet [John Wynne] Griffith [(1763-1834)]; accompanied on his mountain excursions by a non-botanical clergyman with good local knowledge. Plants include: 'Cardamine petraea' notes and observations; specimens for Smith of the three rarer 'Arenaria', 'Polypodium lonchitis', 'Isoetes lacustris', and 'Subularia aquatica'; seed of 'Saxifraga palmata', 'Cerastium latifolium', 'Subularia aquatica', 'Cerastium alpinum', and 'Anthericum serotinum'; 'Formentilla ceptans' with flowers of the 'Formentilla' and 'Potentilla', [William] Withering thinks the two genera should be united. Apologises for not sending rare Welsh plants to [James] Sowerby as intended.

At Smith's request sends specimens of 'Cardamine petraea', 'Subularia aquatica', 'Arenaria verna', 'A. laricifolia', and 'A. juniperina', and also 'Cochlearia groenlandica', 'Saxifraga palmata', 'Serratula alpina', 'Solidago cambrica', and 'Cardamine hastulata' he now determines as 'Arabis hispida' Linnaeus; requests they be returned except the two Smith likes best. Considers 'Arenaria juniperina' and 'A. laricifolia' varieties of the other; observations on this and other plants sent.

'Cistus marifolius' of "English botany" has every flower with only 4 petals. Glad to accept Cornish specimens; requests 'Pisum maritimum' of Norfolk coast.

In addition to plants already mentioned, sending: 'Gallium boreale', 'Scutellaria minor', 'Silene acaulis', 'Gnaphalium rectum', and 'Veronica spicata' or 'V. hybrida'. Found 'Lobelia dortmanna' in the alpine lakes; offers to send catalogue of the plants he found [on his Welsh botanical excursion].
