Clusia salicifolia (Clusiaceae), a new hemiepiphyte species from Costa Rica and Panama

Abstract

SummaryWe describe and illustrate Clusia salicifolia (Clusiaceae) a new species from Central America. This new species is different to all related species for its hemiepiphytic habit, narrow leaves with acute to acuminate apex, reticulate resin canals, staminate flowers with quadrangular androecium with 30 – 47 free stamens, and pistillate flowers with 4 stigmas and 4 pairs of stamen-like staminodia. The species is known from a limited number of localities in lowland wet forests in Costa Rica and Panama and is here assessed as endangered under the IUCN criteria.
