SUPPLEMENT TO THE SPECIES OF CALAMUS. 
PREFACE. 
PRRONI OER 
I Hap just completed the monograph of the genus Calamus published in Vol. XI 
of these Annals, when a large amount of new material was put into my hands, 
derived mainly from the botanical explorations undertaken in the Philippines by 
authority of the American Government under the direction of Mr, Elmer D. Merrill 
and also by the private exertions of Mr. A. D, E. Elmer and Mr. A. Loher. 
Another important source of new species has been the collections of the Buiten- 
zorg Herbarium, which were forwarded to me at Florence by the Director of that 
establishment: these contained valuable specimens collected many years ago by the 
late Mr. Teijsmann, during his numerous voyages in various parts of the Malayan 
Archipelago, and those collected by Dr. Hallier, the botanist of the recent Dutch 
explorations in the interior of Borneo. 
I have also to thank the Directors of the botanical establishments of Kew, Paris, 
Berlin, Breslau and Singapore, for the loan of the novelties contained 
in the 
Herbaria under their charge. 
As a result of these new acquisitions the total number of species of Calamus, 
which at the time of the publication of my monograph amounted to 201, is now 
raised to 256. 
After a careful general revision of the entire genus, I have to make only the 
following alterations in the nomenclature already adopted in my monograph. 
Calamus Delessertianus Becc., is to be eliminated as a species, as it turns out to 
be identical with C. tenuis Roxb. 
Calamus Kunzeanus Becc., was founded upon some detached fruits, which after 
careful comparison have proved to be those of a Puyafetia, probably of P. flaris 
Bece. (Vide ** Webbia" iii, p. 244.) 
C. Harmandi Bece. I now hold to be the type of a distinct genus (Zalaccella 
Harmandi Becc. in **Webbia ii, p. 244.) 
C. Martianus Becc. is a synonym of C, penicillatus Roxb., which name takes 
the precedence. 
Q. bubuensis Becc. is the male-plant of C. brevispadiz Ridley, which name also 
takes the precedence. 
The new additional species alter considerably the geographical data already 
given at p. 45 of this volume of the Annals, especially in regard to the floras of 
the Philippines, Borneo, the Malayan Peninsula and Indo-China, and accordingly 1 
think it useful to give a new enumeration of the species inhabiting the above 
mentioned regions.
