C. domestica major, Rumph (C. piirpiirascens, Bl. or another species belonging 

 to the same group). It is not e]uite impossible however that he mixed up 

 different species in his description, for the description of the bulb, showing 

 a high yellow central part and a white cortex does not apply to any other 

 known Java species. At all means the species is not indigenous at Ambon. 



Timor? A spike of a lateral flowering species in the Bzg. Herbarium, 

 sent by de Castro, shows a great resemblance to C. Zerfoana, Roxb. -, there 

 is no indication whether it is spontaneous or cultivated. Also C. porphyroianica, 

 SCHUM. (see below) belongs probably here. 



Celebes? A specimen collected by Koorders in Minahassa, 19671B., 

 was determinated by Ridley as C. Zedoaria. If this specimen belong to a 

 lateral flowering plant the determination may be right. But it is badly 

 preserved and there is no trace of the inferior stem-scales. So it must hold 

 a place among "Dubia". 



Sumatra: Forbes 1. c. discovered at Surulangan near Djambi in the lower 

 forest in great abundance a species which he takes to be C. Zedoaria. 



C. sumatrana, Mig. was reduced by Ridley to C. Zé'ûfoom but he must 

 have overlooked the fact, mentioned in the description, that the inflores- 

 cence is central. 



Borneo: Specimens collected by miss Gibbs (no. 3956) on the Kinibalu 

 at 1000 M. were reduced by Ridley to C. Zedoaria (Ridl. in Gibbs, 1914).
