| 英文摘要 |
Begonia mizoramensis (Begoniaceae) under Begonia sect. Platycentrum (Klotzsch) A.DC. is described as a new species from Mizoram, Northeast India. It shares similarities in habit, leaf morphology and inflorescence with Begonia longifolia Blume and Begonia acetosella Craib, but differs in several characters, including longer internode, anthers with dehiscence extending beyond half their length, shorter pedicel in pistillate flower and a puberulent ovary with unequal wings. Taxonomic notes and pollen micromorphology are presented to confirm its novelty and sectional placement. Based on the available data, the newly discovered species has been provisionally assessed as Critically Endangered (CR) under the IUCN Red List Categories and Criteria. |
