Polytoca digitata (L.f.) Druce, Rep. Bot. Soc. Exch. Club Brit. Isles 1916: 641 1917. (syn: Apluda digitata L.f.; Coix heteroclita Roxb.; Polytoca bracteata R.Br.; Polytoca heteroclita (Roxb.) Koord.);

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.
