Abstract: Epidermal structures of leaf and palynological data plays a dominant role in aggregating data to resolve taxonomic problems and helps to delimination of taxa. The present study assesses the pollen morphology and leaf epidermal characters of five species of Clauseneae tribe of Rutaceae viz., Murraya paniculata (L.) Jack, Murraya koeingii (L) Spreng., Micromelum minutum J.G. Forster) Wight & Arn, Glycosmis pentaphylla (Retz.) Corr., Clausena heptaphylla Wight & Arn.. Epidermal characters such as stomatal type,stomatal shape,stomal index,stomatal frequency,trichome type etc were studied. Erdtman method(1960) of acetolysis was used to study the pollen morphology and examined under LM. In all studied genera anomocytic stomata are prominent. Pollen grains of all genera are spherical in shape except Micromelum in which pollen grains are elliptic in shape. Epidermal and palynologcal features of investigated genera strengthen their position of retaining in the same family. Both foliar morphological as well as palynological data correlate with external morphological data of all the studied taxa.
