Account of his botanical tour of the the Connemara area of the county of Galway, Ireland, undertaken in August and September 1801, and his discovery of 'Eriocaulon decangulare'. This area had never before been explored by botanists except for Llhwyd in 1699 [Edward Lhuyd ? (1660-1709), Keeper of Ashmolean Museum, Oxford, 1690-1709]. Brief account of geography of Connemara.

Lists numerous authorities and previous descriptions of the 'Eriocaulon decangulare' he discovered, including: Linnaeus "Sp. Pl." 129 "Mantissa alt." 167 327, "Philosphical Transactions of the Royal Society" v.59.241, [John] Lightfoot "Scot" 569, being the 'Nasmythia articulata' of [William] Hudson "Ang" ed. alt. 414-415, the 'Eriocaulon septangulare' of [William] Withering ed. 3.184, the 'Eriocaulon decangulare' in "Flora Carolin[ian]" 83, Lamarck "Encyclop" tom.3.276. Jancinelle d'ecangulare, "English Botany" vol.II. 733, the 'Eriocaulon septangulare' of [Carl Ludwig] Willdenow "Sp. pl." v.1.486. It inhabits the edges of bodies of water across Connemara and Galway. Analyses its character as described in "English Botany", and by Lightfoot and Hudson. Believes Hudson should have used the trivial name 'reticulata' and not 'articulata', and that the generic name was changed to 'Nasmythia' to honour [John] Nasmyth [(1557-1613)], botanist and surgeon to James I. His own observations on its character. A specimen of his 'Eriocaulon' is enclosed [extant].

Intends in his "Flora Hibernica" to only publish plant locations personally verified by himself in or with a living specimen.

Specimen, 'Eriocaulon'.
