This genus though based on a plant obtained in Johore. 1 think 

 must include one at least and probably both of the plants described 

 by Schumann under the section Geocharis of Alpinia vis. A- macrostemon 

 Schumann of Sumatra, and probably Alpinia decurva Ridley a New 

 Guinea plant. I have therefore adopted Schumann's sectional names as 

 a generic names for these plants. Schumann who included a great many 

 and very varied plants in the genus Alpinia noted the fact that both 

 the above mentioned plants resembled the genus Riedelia, and it is 

 possible that A. decurva Ridl. may belong to that Papuan genus. I 

 cannot see any connection with or resemblance to the plants of the 

 genus Geostachys, as suggested by him.
