 a tall or short peduncle covered with long green sheaths, 

 raceme erect many flowered. Flowers orange or red very 

 shortly pedicelled. Bracts very small spathaceous. Ca- 

 lyx tubular trifid, lobes caudate ciliatc. Petals as long 

 somewhat similar. Lip deeply bifid into two narrowed 

 linear lobes base adnate to the corolla. Stamen filament 

 broader than the anther involute forming a tube with the 

 lip, with two short subulate staminodes at the upper 

 angle. Anther broad oblong with an entire ovate ap- 

 pendage. Style stout. Stigma obcuneate curved sub-

Johore, Sumatra and Borneo. 



This genus though based on a plant obtained in Johore, 

 I think must include one at least and probably both of 

 the plants described by Schuman under the section Geo- 

 churls of Alpinia vis. A. macrostemon, Schumann of 

 Sumatra, and probably Alpinia decurva, Ridley a Xcw 

 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 Iiiedc- 

 lia, and it is possible that .4. decurva, Eidl. may belong- 

 to that Papuan genus. I cannot see any connection with 

 or resemblance to the plants of the genus Geostacliys, 

 as suggested by him.
