XVI International Botanical Congess
The genus Larnax (Miers) Huntz. consists of about 16 species of herbs, shrubs and small trees that inhabits tropical montane and premontane humid andean forests of Southamerica, ranging from Venezuela, Colombia and Ecuador to Northern Peru. In Peru there are seven taxa properly described, of which five are endemics, however the finding of the new species, suggests that Northern Peru is the centre of distribution. For that we are presenting a preliminary synopsis as a result of the critical revision of herbarium material, and of the last collections, in addition to this, we are providing its morphology, distribution, ecology, uses, phenology and relationships.
