DESCRIPTION OF SPECIES 265 
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 is discussed 
in the section on paper. Observations on its rate of growth are 
given later. This species is illustrated in Plate I and Plates 
XXVIII and XXIX. 
SCHIZOSTACHYUM TEXTORIUM (Blanco) Merr. KALBANG. 
Local 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 XX XI), 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 XX XIII), 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. fenizii (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.
