LINNEAN2762

From:
Richard Duppa
To:
Sir James Edward Smith
Date:
16 Jul 1827
Source of text:
GB-110/JES/COR/4/75, The Linnean Society of London
Summary:

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].
