Observations on the moving of Ireland's only indigenous heath to the genus 'Dabaecia' [sic]. Asks whether any of the four English heaths are wild in Ireland and if not whether the bogs of Ireland are composed of the roots of 'Salix herbacea' or 'Dabaecia', or another plant. Asks whether 'Erica vulgaris', 'Erica cernua' or 'Erica tetralix' are found along with 'Erica vagans' in Cornwall.

[Duppa incorrectly names 'Dabaecia', which is a non-existent genus. Pleasance Smith (see PubInNote below) believes he probably meant 'Menziesia', and says the Irish heath plant was originally named 'Andromeda dabaecia' by Linnaeus].

Encouraged to write to Smith by the "persevering attention bestowed by [Smith] upon the progress & the wishes of young botanists, of which he possess so many solid proofs in [Smith's] works".

Discusses apparent ambiguity in earlier editions of "English botany" and "English flora" over the 'Ophrys' species considered 'O. apifera' by Haller and 'O. adrachnites' by Professor Murray; errors respecting localities; encloses sketches, to be returned; William Hutchinson of Hythe, [Kent], [Patrick] Keith [(1769-1840)] author of "Physiological Botany", Robert Price of Lyminge, [Kent], and himself all think it is variety of 'O. apifera'; detailed history and observations.

Provides localities for various local plants.
