Abstract

Anatomical studies and leaf architecture are the important tools for the study of plants. They also help in the correct identification of genera and species which are morphologically difficult to delimit. Identification of members of the family Lauraceae are also such morphologically challenging genera and species but of economic value. Hence, the present study was undertaken. The leaves were cleared and stained with saffranine to study the venation pattern and unique feature to find out anatomical marker by using a microscope. Four species of Actinodaphne and three species of Cryptocarya were collected and their venation pattern was studied. Cryptocarya is valued for its timber and other medicinal uses, Actinodaphne hookeri Meissn. is one such medicinal plant whose leaves have been traditionally used for diabetes and disorders of the urinary tract. Based on the leaf architecture, the species could be separated. A key to separate the species was also provided herewith. Three types of venation patterns were found namely Pinnate camptodromous Eucamptodromous, festooned brochidodromous and Acrodromous type. The highest vein orders were 5o and 7o.
