Mindanao: Cabadbaran (Mt. Urdaneta), Province of 

 Agusan, August 1912, number 13646. Gathered in moist 

 stony ground of jungled woods along the Catangan creek at 

 750 feet altitude. "Dowang-dowung" in Manobo. 



Mr. Elmer's plant of Calamus Cumingianus Becc, was based 

 onCuming 762 and with which however a rigorous comparison 

 is difficult, owing to the incompleteness of the latter. On Ai- 

 mer's specimens the leaf sheaths are 4 to 5 cm. thick and 

 are quite smooth or unarmed, the leaves terminate la 

 gradually much reduced leaflets; these are narrowly oblong, 

 somewhat concave underneath and inflated in their upper 

 portion, are green on both sides but paler so beneath 

 and quite devoid of any kind of a powdery coating. The 

 partial inflorescences have the lower spikes divided into 

 smaller spikelets; the fruits are small and globose, ped- 

 icellate like those of Calamus symphysipus Mart, but with 

 shorter pedicels.
