Two New Genera of Gesneriaceae from Southeast Asia

doi:10.7525/j.issn.1673-5102.2025.06.003

Abstract

Abstract:

The genus Loxocarpus R. Br. sensu lato is the endemic group of Southeast Asia and Sundaland. The species in Loxocarpus exhibit differentiation and diversity in floral organs with similar habits and morphology in vegetative organs and fruits. However， evidence from molecular phylogenies indicates that Loxocarpus sensu lato is polyphyletic. According to correlated morphological characters combined with molecular data， we separated Loxocarpus sensu lato into three genera， including Loxocarpus sensu stricto and two new genera， i.e. Yaoa and Paraloxocarpus. In the present study， the three genera were described with a key to them， and 21 new combinations were proposed.

Key words: Southeast Asia, new genera, new combinations, Loxocarpus, Yaoa, Paraloxocarpus, Gesneriaceae
