In addition to the above species which is cultivated only, there are no less than 

 four other distinct arborescent species of Bambusew more or less abundant in 

 the Lamao region, which from lack of flowering or fruiting specimens it is impos- 

 sible acenrately to identify at this time. These species are as follows: 



2. Bambusa monogyna Blanco, PI. Filip. ed. 2 (1845) 187. 



kSimilar to Bambusa blumeana in size and habit, but the culms naked at the 

 base — that is, not protected with spiny branches. T., Cauayan quiling.

 4 feet or slightly more. T., Anas. 



4. Bambusa lumampao Blanco, 1. c. 189.

 almost pure stands under scattered large trees such as Parkia, Albi~z\a, Anisoptera
