     Found in Cameroon and Madagascar.

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.

Taxonomic Diversity:
     Comprises about five species.
