anther, grooved on the face, as a continuation of the loculi; appendix of

 of the petiole. Rhizome short or wanting, bulbs or tubers in groups.

B. Euciircuma. Bracts mostly not adnate over the middle; only in

 species of the Exantha, only as a narrow furrow, not containing pollen. 



Full-grown leaves acuminate at the base, Ligulawithoutelongatedauricles. 

 Rhizomes lengthened, consisting of merithallia and forming lateral branches. 

 Fourteen species in Java, two in Sumatra.
