Escobin, R.P. | Conda, J.M. | Pitargue, F.C.Jr.
A total of 43 species under three genera and three families exhibiting included phloem are presented. Three types of included phloem are recognized, i.e., a) complete bands, b) patches and c) diffuse. Of the more than 3,700 species, 124 families and 600 genera of Philippine woods, only three genera exhibited included phloem, namely: Avicennia Verbenaceae (APG:Acanthaceae), Memecylon (Melastomataceae) and Aquilaria (Thymeleaceae). The standard procedure in wood anatomy was used to study the presence of included phloem and macro-physicomechanical characters of the specimens. Three representative species for each of the genera are presented in photographs. The taxonomic status of the species is based on the currently accepted systems of classification; their current uses, distribution and ecology are also included. An artificial key to the identification of genera based on the character of included phloem is likewise presented.
