The stem anatomy of 9 Philippine woody vines was studied to provide data for proper identification. The species studied included: Ichnocarpus frutescens (hinggiu) Streptocaulon baumii (hinggiu-kalabau) Entada phaseoloides (gogo) Merremia peltata (bulakan) Anamirta cocculus (bayati) Rourea volubilis (kamagsa) Freycinetia formosana forma banahaensis (vayasubas) Freycinetia vidalii (white vine) and Freycinetia merrillii (red vine). The striking anatomical features of the vine species are the following: presence/absence of growth rings rays and sheath cells; pores extremely small to very small almost exclusively solitary except for gogo which exhibited pore multiples; ray multiseriates ranging from 2 to 23 cells wide; and all species thin-walled. The presence of tyloses in bayati kamagsa and bulakan and absence of rays and growth rings in the samples of genus Freycinetia are other important features that would separate them from other vine species studied.
