Triolena anisophylla (Melastomataceae), a new and threatened species endemic to Panama
摘要
A new species of Triolena, endemic to Colón Province, Panama, is described and illustrated. The specimens of this taxon were previously identified as Triolena lanceolata, but closer inspection has shown them to be morphologically and geographically distinct. Triolena anisophylla K.Samra & Michelang. grows on rocks and tree trunks along rivers in Colón Province. This species is distinguishable by its strongly anisophyllous leaves and unique trichomes on the adaxial surface of the leaves. A complete description, distribution map, preliminary conservation assessment, taxonomic notes, and regional key are provided.
