iC. polygamus] | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 501 
Description.—‘‘Scandent. Leaflets thirty-four pair, regularly alternate except the 
terminal two, which are united, lanceolate, seven to nine-nerved ; margins entire and 
smooth, a pencil of bristles from the apex of each, Sheaths flagelliferous, ( Rox- 
burgh 1. c.) 
Hastrat.—“ Found by Mr. Roxburgh in the forests of Pulo Pinang running 
over trees. It is more slender than the common rattan, and less so than the next 
species, C. gracilis ( Roxburgh l. c, ).” | 
_ OssrmvarroNs.—l have reproduced above all that Roxburgh has written about 
this species of which no authentic specimens are known. As I have already said 
in the observations under C. javensis peninsularis, if for “ thirty-four pairs of leaflets.’ 
in Roxburgh’s description 3-4 be substituted, this might apply to it, and therefore 
the name of C. javensis ought to be replaced by that of penicillatus, this having 
been proposed a few years before ( 1832).

OBSERVATIONS.—I have not seen Roxburgh's specimen of this species of which 
that author has left only the meagre description reproduced above. I am, however, 
inelined to identify it with C. Flagellum Griff. If this could be proved, the specific 
name of polygamus, though an improper one, as all Calamus on superficial examin- 
ation appear polygamus, ought to have precedence over that of Flagellum, this 
having been proposed many years later than the other.
