cari in Ann. Bot. Gard. Calcutta 11 (1908) 357. It has been 

 confused by various authors with Calamus equestris Willd., with 

 C. javensis Blume, and with C. maritimus Blume.

 (type!). 



Palmijuncus acidus Rumph. Herb. Amb. 6: 119, t. 58, f. 2, E. 



A very imperfectly known species, known only from Rumph- 

 ius's description and figure. By various authors it has been 

 erroneously reduced to Calamus barbatus Blume; to Calamus 

 oblongus "Linn.," which does not exist [Hasskarl, Neue Schliissel 

 (1866) 102] ; and to Daemonorops barbatus Mart. 



CALAMUS sp. 



Palmijuncus aracanicus Rumph. Herb. Amb. 5: 107. 



A form of entirely uncertain status ; it was thought by Schultes 

 to be referable to Calamus oblongus Reinw., and by Kunth to be 

 Calamus latifolius Roxb. 



CALAMUS sp.? 



Palmijuncus viminalis s. ua huay Rumph. Herb. Amb. 5: 109. 



Entirely indeterminable from any data given by Rumphius; 

 it may not be a Calamus at all.

Palmijuncus calapparius Rumph. Herb. Amb. 5: 98, t. 51. 

 Amboina, Lateri, Robinson PL Rumph. Amb. 23, September 5, 1913, in 

 forests, altitude about 250 meters, locally known as rotang bulu rusa. 



The identification of this specimen with both Palmijuncus 

 calapparius Rumph. and Daemonorops calapparius Blume has 

 been made by Doctor Beccari, who has given a detailed descrip- 

 tion of the species from Amboina specimens.* Linnaeus 

 originally reduced this to Calamus rotang Linn., Sp. PL ed. 2 

 (1762) 463, in which he was followed by numerous authors. 

 Loureiro, Fl. Cochinch. (1790) 209, reduced it to Calamus 

 petraeus Lour., but the Cochin-China species actually described 

 by Loureiro is entirely different from the Amboina plant, and 

 Beccari thinks it probably a species of Korthalsia or Plectocomia.
