A Taxonomic Revision of the Andean Genus Pineda (Salicaceae)
Pineda is a small neotropical genus of Salicaceae found in high altitude, semi-arid scrub of Bolivia, Ecuador, and Peru. One northerly species, Pineda incana Ruiz & Pavón, is recognized, and a new species from Bolivia, Pineda ovata M.H. Alford & Zmarzty, is described. The two alopatric species are distinguished by leaf shape, sepal size, and frequencies of 4- and 5-merous flowers. The new species significantly alters the generic description, eliminating stellate pubescence and pinnate venation as generic characters. Rather, the genus is now more accurately characterized by the combination of 4-5-merous hermaphroditic flowers and presence of receptacular disk glands and outer filamentous staminodes.
