Polytoca digitata (L.f.) Druce (As per eFI thread: It is clear that Chionachne koenigii is definitely different from Coix gigantea even when treated as Chionachne gigantea. As per priority rule, the genus Coix will prevail over Chionachne, even if someone wants to consider both under the same genus. But there are very distinct differences between the two genera. The new combination of Chionachne gigantea with all the others being treated as synonyms is published in the revision of Chionachne in Blumea. But definitely there is some mistake. I have not yet gone through the full paper of revision of Chionachne published in Blumea. Once I get a copy of this and go through, I will respond further)
Polytoca wallichiana (Steud.) Benth. (E. Himalaya to Indo-China: Andaman Is., Assam, East Himalaya, Myanmar, Nicobar Is., Thailand, Vietnam as per POWO)
Polytoca (Poaceae) page with comparative images:
Pl. go through Polytoca (Poaceae) page with comparative images of species in efloraofindia. On clicking the link of species, one can check the complete details.
I request you to pl. go through & point out mistakes, if any. I hope this will aid in identification in future. If anybody can send images of other species of this genus (for incorporation in the website), if any, or can identify unidentified images, it will be really nice. Pl. circulate it widely, for the benefit of all concerned.
Thanks a lot, Manoj Chandran ji, for most of the identifications.
