Abstract

Six species of Phoebe have been studied. The studied species are economically important and are a valuable source of wood and timber which are used as a substitute for teak and Phoebe lanceolata is medicinally important. The present study was undertaken to identify the six species based on the venation pattern. The types of venation patterns found are Type of venation is Pinnate camptodromous eucamptodromous and Pinnate camptodromous with festooned brochidodromous type. The species studied are Phoebe angustifolia, P. attenuata, P. cooperiana, P. goalparensis, P. lanceolata and P. paniculata. The type of venation found in them is pinnate camptodromous eucamptodromous and festooned brochidodromous. The species are further separated based on the higher vein order and angle of origin of tertiary veins, areole development and presence or absence of tracheoids.

Keywords: Phoebe, venation, pinnate, eucamptodromous, festooned brochidodromous.
