Description:
Pelliciera is a genus of mangrove trees with distinct showy flowers with five petals subtended by two
\nlarge foliaceous bracts. The genus, thought to be monotypic, only containing P. rhizophorae, was classified recently
\nin the small diverse family, the Tetrameristaceae. This distinctive genus occurs in a relatively restricted distribution
\nin Central and northern South America in the Atlantic-East Pacific region. In this recent decade, two varietal forms
\nhave been reported across its range, of which one appears to be a colour morph referred to much earlier as P. rhizophorae var. benthamii. The taxonomic status of the earlier morph was, however, insufficient to warrant individual
\nrecognition at the time, so the genus remained monotypic with no varietal forms. The aim of this treatment has been
\nto review the systematic history of the genus, to thoroughly re-assess available observations and to re-evaluate
\nthe current taxonomic status. In conclusion, the genus is recognised now as having two closely related species,
\ndescribed here as P. benthamii along with a redefined P. rhizophorae. Characters such as leafy bract colour, leaf
\ndentition and petal shape used in their discrimination are provided, along with notes on the ecology, phenology, a
\ndiagnostic key, and a revised distribution map that displays the oddly overlapping occurrences.
