DESCRIPTION OF SPECIES 15 



dense globose, widely scattered heads the larger of which are 

 about 2 centimeters in diameter. See Plate XL 



Genus DEN DROCALAM US Nees 



Spikelets large; leaves large D. latiflorus. 



Spikelets medium-sized; leaves long D. curranii. 



Spikelets very small D. merrillianus. 



This genus of large erect bamboos is represented by three 

 species. It is economically unimportant and none of the species 

 are especially abundant. 



DEN DROCALAM US CURRANII Gamble. 



A rare species known only from Sampaloc, Tayabas, and 

 the Island of Polillo off the coast of Luzon, and possibly not 

 distinct from Gigantochloa levis. 



DENDROCALAMUS LATIFLORUS Munro. Botong. 



Common names: botong, bolong-sina (Bikol, Bisaya) ; butun (Bisaya) ; 

 kaboloan, patong (Bikol); kaivdyan-sina (Tagalog). 



This is a tall, tufted, spineless bamboo apparently of general 

 distribution in the central Philippines. It is frequently utilized 

 for building purposes, but is not considered to be good material 

 for basketry. 



DENDROCALAMUS MERRILLIANUS Elm. Bayog. 



Common names: bayog (Ilocos) ; kawdyan-bayog' (Pangasinan) . 



This bamboo is apparently widely distributed in the Philip- 

 pines. It is a tall graceful bamboo with slender stalks forming 

 large clumps. The culms have very thick walls and prominent 

 nodes. They are used for vehicle shafts and for other purposes 

 where great strength is desired. The green culms of this bamboo 

 are split and made into ropes, used particularly for hauling logs. 

 A flowering specimen is shown in Plate XII.

 ing almost impenetrable thickets under favorable conditions.
