Leaflets of Philippine Botany

concolor, the whiplash like very slender and clawed flagel- 

 lum arising nearly opposite the leaves, 



Mindanao: Cabadbaran (Mt. Urdaneta), Province of 

 Agusan, August 1912, number 13902. Inhabiting dense 

 woods or forests on steep slopes near the Catangan 

 creek at 3000 feet altitude. Its vernacular name is '"Bo- 

 lanog" in Manobo. 



Luzon: Irosin (Mt. Bulusan), Province of Sorsogon, 

 July 1916, number 16701. 



The leaves as is usual in that species terminate in 

 gradually much reduced leaflets, these are elongate to 

 lanceolate, gradually acuminate, covered on the lower 

 surface with the characteristic subochraceous powdery 

 coating as in the typical specimens from Celebes. The 

 Mindanao specimens however have spathes of the spikelets 

 very closely sheathing, whereas in the specimens from 

 Celebes the same spathels are somewhat loosely infun- 

 dibuliform. In every other respect but especially in the 

 characteristic pedicellate fruits, the plant from the Philip- 

 pines is identical with that of the Celebes. 



This size of rattan is much used locally in the construct- 

 ion of chairs. These however are of a more or less inferior 

 kind, probably because of a lack of the proper tools, 

 machines and workmanship. This same grade is also 

 used to make pack saddles for horses and carabao. At 

 Lucban I have seen these animals brought into rattan 

 workshops for the saddler to take their proper measure 

 for a saddle. The idea was a good one, but the finished 

 article was very crude and more often a misfit.
