Linnaeus, Sp. PL ed. 2 (1762) 463, originally reduced this 

 through error to Calamus rotang Linn. Gaertner, Fruct. 2 

 (1791) 267, cites it under Calamus zalacca Gaertn.= Zalacca 

 edulis Reinw. Most authors have cited it under Zalacca (Sa- 

 lacca) edulis Reinw., but Martius placed it under Zalacca blu- 

 meana Mart., which is merely a synonym of Reinwardt's species.

CALAMUS ALBUS Pers. Syn. 1 (1805) 383 (pp. excl. syn. Lour.) (type!);

 in forests, altitude 200 meters; locally known as rotang tuni. 



The specimen cited above has been identified with Calamus 

 albus Pers. by Doctor Beccari. Palmijuncus albus Rumph. has 

 been reduced by various authors to Calamus rotang Linn, and 

 to Calamus rudentum Lour., most of the references in literature 

 being to the latter species. Loureiro made the reduction to 

 Calamus rudentum Lour, in the original description of that 

 species, but the type was a Cochin-China specimen, and the 

 species is certainly not the same as the Amboina one. Strictly 

 following rules of nomenclature, the name Calamus albus Pers. 

 belongs with Calamus rudentum Lour., as a synonym, but I have 

 here followed Beccari in applying it to the Amboina plant. 



CALAMUS GRAMINOSUS Blume Rumphia 3 (1837) 31 (type!). 

 Palmijuncus albus graminosus Rumph. Herb. Amb. 5: 104. 



A species known only from Rumphius's description; see Bec- 

 cari in Ann. Bot. Gard. Calcutta 11 (1908) 499. It has been 

 reduced by various authors to Calamus rotang Linn., C. rudentun 

 Lour., and C. adspersus Blume, but is manifestly none of these. 

 It may be a form of Calamus albus Pers. 



CALAMUS RUMPHII Blume Rumphia 3 (1837) 38 (type!). 



Daemonorops rumphii Mart. Hist. Nat. Palm. 3 (1850) 331. 

 Palmijuncus verus angustifolius Rumph. Herb. Amb. 5: 105, t. 51f, f. 2. 



A species known only from Rumphius's figure and description ; 

 see Beccari, in Ann. Bot. Gard. Calcutta 11 (1908) 400, who 

 considers it to be allied to Calamus palustris Griff. It has been 

 erroneously reduced by various authors to Calamus rotang Linn.,
