Phylogeny and Classification:
Phylogenetic anaslyses show that Aulotandra and Siphonochilus form a monophyletic group. Newman (2007)has transfered Aulotandra from subfamily Alpinioideae, tribe Alpinieae, to subfamily Siphonochloideae. Further study is merited in the African genera of Aulotandra, Siphonochilus and Kaempferia.
Comprises about five species.
