Abstract
Eucrosia is a small, rare, polymorphic, central Andean genus of petiolate-leaved Amaryllidaceae. Seven species and two varieties are recognized. Three species are endemic to Ecuador and two to Peru; two additional, largely Ecuadorean, species are occasional in Peru. Eucrosia is primarily a xeric, lowland, floristic element, inhabiting seasonally dry vegetation of the lower, western slopes and Pacific coastal lowlands, with a single species adapted to montane rainforest understory. The genus is marked by its petiolate leaves with wide laminae; weakly to strongly zygomorphic flowers; long, declinate stamens in all but one species; and the presence of androecial nectar glands in five of the species. Pollen exine morphology exhibits a phylogenetically significant transformation series from semi-tectate/reticulate to verrucate/fossulate. The most common somatic chromosome number is 2n = 46. The flowers are putatively adapted for butterfly pollination, but a single report of hummingbird visitation is recorded for E. eucrosioides. Phylogenetic analysis places E. stricklandii as the most primitive species in the genus. Phaedranassa and Rauhia are the genera closest to Eucrosia, and it is hypothesized that Stenomesson is ancestral to these three.
