The present study shows that Poneorchis nana (King & Pantl.) Soois a new record for Uttarakhand. Bulbophyllum secundum Hook. and Eulophia hormusjii Duthie that have earlier beenmerged into other species, during the present study after detailed scrutiny, have been treated as separate species.Androcorys pugioniformis (Lindl. ex Hook. f.) K.Y. Lang. has been rediscovered after a century gap. Nomenclature hasbeen updated as far as possible with the help of available recent taxonomic literature.
