Distribution. 



Amboina: (RUMPH, Binnendijk, C. H B , Robinson no. 144). 

 Molucca's: South-east islands; Key. (RUMPH). 



Borneo: Bukit Limpai, (TEYSMANN no. 10944 in H. bog, nom. vern. 

 Assem putjuk). Mt. Kenepai. (HALLIER 1894 b, in Herb, bog., 1893—94). 



Ceram: (north) Tableland south of Wahaai, 150 M., frequent in forest, 

 (RUTTEN no. 10. ,,nom. ind. Galoba djantoen fl. lightred, 4M. high, fruits 

 eaten"). South Ceram, in a garden near the sea at Woloe. (RUTTEN No. 

 703, fl. lightred, 5 M. high). 



This species has been introduced into the Bot. Gard, of Buitenzorg 

 from Amboina before 1866, and was mentioned as Donacodes incarnata 

 ,T. et B. in the second edition of the Catalogue. The Amboina plants have 

 died out in the garden, but an authenthic specimen still remains in the 

 Herbarium, consisting of some adult leaves and some young flowering- 

 scapes. Evidently the same species though with rather thicker scapes was 

 collected in Borneo first by TEYSMANN (1875 ?) afterwards by HALLIER 

 (1894), and lastly ROBINSON collected specimens in Amboina, identical with 

 those of BINNENDYK. 



Though there is an abundance of names to this species, the only 

 description existing, being the base of them all, is that of RUMPHIUS, which, 

 excellent in its kind, gives not many phytographical details. A. few flowerbuds 

 in the specimens of BlNNENDljK's and ROBINSON'S and open flowers 

 preserved in spirits recently sent from Ceram by Dr. RUTTEN allow me 

 to complete the description.
