Jana Skornickova: I have never seen this in Vietnam and in all likely hood, this is new. There are some Alpinia species in Peninsular Malaysia, which have similar structure of inflorescence with fairly long branches ending with crowded cincinni of flowers, but never seen that in Vietnam. It is interesting, because there seem to be affinities between flora of Peninsular Malaysia and Vietnam. Although for gingers the species do not overlap, there seem to be pairs of taxa (genera/species) which are somewhat similar but not same.
