The anther resembles most that of the H. minor-group of Hornstedtia, 

 only the connective is very small, and narrower than the thecae themselves. 

 The bracteole is cymbiform, open and not tubular. 



The next allied form of this species seems to me Ämomum macrodon, 

 so called for the distinct dentiform staminodes by SCORTECHINI reduced 

 to Hornstedtia by K. Schumann (wrongly macrodus) see SCORTECHINI 

 I c, t. 12 with which it agrees in some important characters: Homoge- 

 nous bracts short recurved, calceoiate lip without auricles, subulate stami- 

 nodes.
