6056567CF2F25E199321D037C398CDA7.taxon	diagnosis	Diagnosis. Sloanea cayapensis resembles S. grandiflora Smith and S. fragrans Rusby, the most morphologically similar taxa, but can be differentiated from them by having short petioles (2 - 7.5 cm), obovate-spatulate leaves, 6 - 8 free sepals, shorter thick and acute-obtuse anthers (1.5 - 2 mm), densely hirsute filaments and styles and by having capsules with large, flexible, curled bristles (2.8 - 6 cm).	en	Guevara Andino, Juan Ernesto, Fernandez-Fernandez, Diana (2020): A new rare and endemic species of Sloanea (Elaeocarpaceae) from the Choco region of Ecuador.

6056567CF2F25E199321D037C398CDA7.taxon	distribution	Distribution and habitat. Sloanea cayapensis is a medium-sized tree only known from two localities on high alluvial terraces along the Cayapas River in the Lowland Evergreen Forests of Equatorial Choco (Ministerio del Ambiente del Ecuador 2013). This area lies in the Choco floristic province, where forest structure is characterised by a canopy 25 - 30 m high, with occasional emergent trees reaching 40 m. High levels of endemism and dominance of families, such as Moraceae, Fabaceae, Meliaceae, Myristicaceae and Lecythidaceae, have been reported for this area (Gentry 1982; Ministerio del Ambiente del Ecuador 2013) and the label of the type specimen indicates that S. cayapensis co-occurs with the following tree species: Terminalia amazonia (Combretaceae), Swartzia littlei (Fabaceae), Matisia cordata (Malvaceae) and Cordia alliodora (Boraginaceae). The climate of this area is rainy near the Ecuador-Colombia border and becomes more seasonal to the south, where it transitions into the Lowland Seasonal Evergreen Forests of the Equatorial Choco (Ministerio del Ambiente del Ecuador 2013).	en	Guevara Andino, Juan Ernesto, Fernandez-Fernandez, Diana (2020): A new rare and endemic species of Sloanea (Elaeocarpaceae) from the Choco region of Ecuador.

6056567CF2F25E199321D037C398CDA7.taxon	etymology	Etymology. From the Spanish word Cayapa, with reference to the Chachi indigenous group that inhabits a great portion of the evergreen lowland forests of the Equatorial Choco in Ecuador. The word Chachi means ' pure' in the Cha'palaachi language. The species name was first proposed by the late Ecuadorian botanist J. Jaramillo as a written annotation on herbarium specimens, but was never validly published.	en	Guevara Andino, Juan Ernesto, Fernandez-Fernandez, Diana (2020): A new rare and endemic species of Sloanea (Elaeocarpaceae) from the Choco region of Ecuador.
