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.
