On behalf of Måns Broo, who is a member of the list but for some reason unable to post, I wonder if anyone can help in identifying the following species of flowers mentioned in a Gauḍīya Vaiṣṇava ritual text in Sanskrit (c. 16th century). The names in brackets are given by a commentator as iti prasiddham, but a search of Hindi and Bengali dictionaries has yielded no results so far:

kāṇva (kaṇahulī)
purandhrī (puṅgavī)
śikhin (curiyā)
rotakī
timirā (triṃtara)
villātaka

Best wishes,
Martin Gansten
