Derivation of epithet
The species was cultivated in Britain from material introduced from the West Indies by Lord Seaforth (Francis Mackenzie Humberston, 1754-1815), governor of Barbados from 1801 to 1806. Lord Seaforth was responsible for the introduction of many living plants to the gardens of England and these are illustrated in early issues of Curtis' Botanical Magazine and Andrews' The Botanists Repository.
