OnseRvations.—Griffith states (Palms Brit. Ind. 34) that he has been unable 
to identify this Calamus, which is considered by him (1. c. 43) as referable to a 
species of the group of C. erectus. I feel, however, inclined to consider C. humilis 
as the young and not yet fertile plant of C. latifolius, which is also a native of 
Chittagong.—See observations under C. latifolius.

OssrRvATIONS.— lhe name C. maritimus was assigned by Blume to the Rotang 
Tsjavos of Rumph, but certainly this is a well-known Javan species, already described 
under its proper name, which is not recognizable from the vague characters assigned. 
to it by the author of the ‘‘ Herbarium Amboinense."

OssrRVATIONS.—I have seen some portions of the specimens of which Blume 
made use for the description of this species and for plate 151 of his ‘‘Rumphia.” 
From careful examination of this material I have come to the conclusion that C. 
micranthus was founded on a. male spadix with very young flowers. apparently of 
C. Reinwardtii, or of a species allied to it, and on the leaves of C. Scipionum. The 
leaflets attributed to C. micranthus are distinctly 5-7-costulate, and it would be an 
extraordinary fact if these were those of a plant which produces a spadix very 
similar to that of C. Reinwardtii, the species of the group to which this belongs 
having always 3-costulate leaflets.—See observations under C. Scipionum. :
