Abstract

Five angiosperm species, Cajanus elongatus (Benth.) Maesen (Fabaceae), Crotalaria meghalayensis Danda & A.K.Pandey (Fabaceae), Mycetia malayana (G.Don) Craib (Rubiaceae), Microchirita karaketii D.J.Middleton & Triboun (Gesneriaceae), and Peliosanthes griffithii Baker (Asparagaceae) are reported as new distribution records for Mizoram, India. Species identification was confirmed through detailed morphological examination, supported by relevant literature and herbarium studies. Comprehensive taxonomic descriptions, distribution data, and photographic documentation are provided.
