Family Poaceae Specialty Crops for Pacific Island Agroforestry (http://agroforestry.net/scps) 3 Subfamily Branch buds are borne only at the nodes and the number of Bambusae branches that emerge varies by species. Branches also have nodes and internodes, and can produce branchlets. Leaves Common names are borne in groups at the tips of the branchlets. The local names for Bambusa spp., the most common Bamboo flowers and seeds are rare. Individual flowers are bamboo of the Pacific, include (PEIR 20�0): small, but borne in longitudinal inflorescences, and seeds of Carolinian: bwai, bwai most bamboos are about the size of a grain of rice.
