"4"^^ . "Lasiocephalus (Asteraceae: Senecioneae) is a high-Andean neotropical genus which represents an autochtonous element in the flora of the equatorial p\u00E1ramo. It comprises ca. 30 species which occur from the montane forest to the highest reaches of the p\u00E1ramo and are distributed from Venezuela to Bolivia. Lasiocephalus comprises two basic growth forms which probably reflect an adaptive variation during the colonization of the p\u00E1ramo habitats, i.e., broad-leaved suffrutescent climbers of the montane forest and ascending subshubs with narrow, subcoriaceous leaves of the p\u00E1ramo. This project suggests a phylogenetic and biogeographic study of Lasiocephalus with the aims to confirm the monophyletic status of the genus, to study the relationships among the species, to reconstruct the mode of colonization of the p\u00E1ramo habitats by this genus, and to study the ecology of the species and their geographical distribution in the context of the climatic and vegetation changes during the Pleistocene.
