Abstract
The present work deals with the venation studies in the genus Machilus of family Lauraceae. The family Lauraceae is commonly called Laurel family which is of great economic importance. Ten species of Machilus are studied namely M. bombycina, M. clarkeana, M. dutheii, M. gamblei, M. globosa, M. khasyana, M. kingii, M. odoratissima, M. parviflora, M. villosa. The type of venation found is pinnate camptodromous with festooned brochidodromous secondaries. The further separation of the species can be done based on tertiary veins, highest vein order, angle of divergence of secondary veins, angle of divergence of tertiary veins and a key has been prepared. The species are so intimate by their leaf morphological characters, it is often difficult to determine their nomenclature types. Hence attempt has been made to recognise the taxonomic value of laminar architecture.
Key Words: Machilus, venation, pinnate camptodromous, festooned brochidodromous
