DESCRIPTION OF SPECIES 19 



a height of about 10 meters, and often nearly exclusively occupy- 

 ing considerable areas. Forester Medina has surveyed two 

 tracts of this bamboo in Bataan Province, one containing 1,200 

 hectares, of which 800 hectares have a dense stand; the second 

 containing 650 hectares, of which more than 40 per cent is 

 covered with Schizostachyum lumampao. There are also very 

 extensive areas in other parts of Bataan, in Zambales, and in 

 the Cagayan Valley. Fifteen small plots of Schizostachyum lu- 

 mampao have been measured in Bataan Province back of the town 

 of Limay. These plots aggregated 3.5 hectares and covered 

 stands at widely separated intervals. The surveys showed an 

 average of 8,983 canes per hectare. One of the surveys of one 

 quarter of a hectare indicated a stand of 19,162 canes per hectare. 



This thin-walled bamboo is the species chiefly utilized in mak- 

 ing the building matting known as sawale. It is also used for 

 making baskets, fences, fish corrals, fish poles, flutes, and for 

 many other purposes. 



Buho has been thoroughly investigated by Richmond as a 

 paper-making material, and it is probably the one species of 

 Philippine bamboo that, without extensive cultivation, promises 

 commercial possibilities for this purpose. This point will be 

 discussed in a bulletin on paper. Observations on its rate of 

 growth are given later. This species is illustrated in Plate I 

 (frontispiece) and Plates XXVIII and XXIX. 



SCHIZOSTACHYUM TEXTORIUM (Blanco) Merr. Kalbang. 



Common name: kalbang (Tagalog). 



This is an erect bamboo with small leaves, which is locally 

 abundant in the Provinces of Batangas and Rizal, Luzon. The 

 stems are used in the manufacture of looms, as they are very 

 straight and smooth. A flowering specimen is shown in Plate 

 XXXII. 



Among the other Philippine representatives of the genus are 

 Schizostachyum palawanense (Plate XXXI), a scandent species 

 known from Palawan and Laguna; S. hirtiflorum (Plate XXVI), 

 a widely distributed species closely allied to and with the same 

 growth form as S. lumampao; S. toppingii (Plate XXXIII), erect 

 or subscandent, reported from Laguna, Rizal, and Mindoro; 

 S. curranii (Plate XXIII), scandent, a species of higher altitudes 

 in northern Luzon; S. luzonicum (Plate XXX), known only from 

 Zambales; and S. fenixii (Plate XXV), reported from Abra, 

 Cagayan, Benguet, Ilocos Sur, and Panay, known as paua in 

 Iloilo, and puser in Abra, Luzon, and there utilized in the manu- 

 facture of baskets.
