25. BAMBUSA Schreb. 
1. B. blumeana Scliult. f.; Hook. f. 1. c. 394. Bamhus arundo Blanco. 
The common bamboo cultivated throughout the Philippines and very doubtfully 
wild in the Archipelago. The base of the culms with numerous stiff spiny 
branches. Malaya. T., Cauayan, Cauayan toioo. 
In addition to the above species which is cultivated only, there are no less than 
four other distinct arborescent species of Bamhusew more or less abundant in 
the Lamao region, which from lack of flowering or fruiting specimens it is impos- 
sible accurately to identify at this time. These species are as follows: 
2. Bambusa monogyna Blanco, FI. Filip, ed. 2 (1845) 187. 
Similar to Bambusa blumeana in size and habit, but the culms naked at the 
base — that is, not protected with spiny branches. T., Cauayan quiling. 
3. Bambusa lima Blanco, 1. c. 189. 
A characteristic spineless species, the internodes often reaching a length of 
4 feet or slightly more. T., Anos. 
4. Bambusa lumampao Blanco, 1. c. 189. 
The most abundant species in the region, frequently gregarious and forming 
almost pure stands under scattered large trees such as Parkia, Albizzia, Anisoptera 
etc., sea level to 300 m., spineless. S^r.-Fil., Cafia boko. 
5. Bambusa sp. 
Similar to the preceding species but differing in sheath and other characters, 
not common. T., Tagisi. 
26. DINOCHLOA Bllse. 
1. D. diffusa (Blanco) Merr. Govt. Lab. Publ. 27 (1905) 93. 
(75, 519 Whitford); (1261 Borden); (6092 Leiberg) ; (2550, 3297 Merrill)

2. D. tjankorreh Btise; Hook. f. 1. c. 414.

Timac.
