The rounded top of the connective which is somewhat longer than half 

 of the loculi does not form a distinct iingula. 



The colour of the petals is snow-white, the flower is for the rest very 

 pale-cream-yellow, the middle-band of the lip dark-yellow. 



Distribution. The species is cultivated in Western Java (Bauten, 

 Soemedang) and central Java (Djocdja) and grows spontaneously in the teak 

 forests; from oriental Java I did not see any specimens. But there is a 

 specimen collected by Backer (11579) on mt. Wilis at 900 M. "dispersed 

 among shrubs", which most probably belongs here, the brown costa and 

 white bracts being mentioned by the collector. Though flowering abundantly 

 throughout the whole raining season, it does not appear to fructificate. 



Outside of Java it is unknown, but specimens of other regions occurring 

 in Herbaria would certainly be labelled C. longa. But it does not occur 

 among the rhizomes sent from Singapore. 



The species was certainly known to Rumphius and it is either this 

 species or C. viridiflora which is represented by tab 68, wrongly quoted as 

 C. Zerumbeth by most authors. The likeness of Rumph's tabula 68 to our species 

 is striking. The tuber described by Rumph by the name of- "//s" or "af/«^//7" 

 (=z tinggang ?) might be a young plant of this as well as of any other species. 



Native names: Certain names in occidental Java: "tinggano'\ or "tis", 

 sometimes "pinggang", in Djogdjakarta "gelenje" or "belenje".
