Distribution, morphology, anatomy and histochemistry of Crepidium acuminatum

Abstract

Crepidium acuminatum is largely confine to the Himalayan region although it has been reported in South India, where its presence distribution needs to be critically studied. This study describes the morphological, anatomical and histochemical aspects of the materials of the authenticated species collected from Himalayas. This study also highlights the features of histochemistry and anatomy that should be used for the correct identification and authentication of C. acuminatum, especially because of the therapeutic importance of the species and its possible adulteration by other orchids.
