[Botany • 2013] Coespeletia palustris • A New Species of Coespeletia (Asteraceae, Millerieae) from Venezuela



Abstract
A new species of Coespeletia from the páramos of Mérida (Venezuela) is described here. This species, named Coespeletia palustris, is found in a few marshy areas of the páramo. It is closely related to C. moritziana, but differs from it in a smaller number of florets in the capitula, larger ray flowers with longer ligulae and longer linguiform appendages, smaller pollen grains, larger cypselae, ebracteate scapes, leaves and inflorescences with more whitish indumentum, larger leaf sheaths, and marshy habitat.

Keywords: Coespeletia, Compositae, Espeletiinae, frailejón, Millerieae, Páramos, Venezuela
