Identification. This taxon is characterized by having an epiphytic-climbing habit, short stems and internodes, fibrous-persistent cataphylls, black glandular-punctate blades, usually pendent inflorescences, small spathes and spadices (<1.0 cm long) and whitish berries. Anthurium scandens subsp. pusillum differs from the typical subspecies ( A. scandens subsp. scandens ) in having spadices with fewer flowers (<13 flowers per spadix), small leaves, and very small spadices (up to 1.0 cm long). In the study area it could be confused with A. tonduzii Engl. , but the latter differs in having intact and deciduous cata- phylls, markedly ovate blades and reddish spadices. Distribution and ecology. Colombia , Costa Rica , Ecuador , Honduras , Nicaragua , Panama , and Venezuela . This taxon generally ocurrs in montane and submontane forests, above 600 m ( Croat 1986b ). On Cerro Pirre, it represents a relatively rare species. Along the elevation gradient, it can only be observed in the montane cloud forest above 1100 m .
