Abstract: The genus Clerodendrum Linnaeus (Lamiaceae) comprises of 23 species and 2 varieties in India of which Northeast India represents 18 species and 2 varieties. Barnadi Wildlife Sanctuary in Assam harbours 7 species of the genus viz., Clerodendrum chinense (Osbeck) Mabberley, C. colebrookianum Walpers, C. cordatum D. Don, C. indicum (Linnaeus) O. Kuntze, C. japonicum (Thunberg) Sweet, C. paniculatum Linnaeus and C. serratum (Linnaeus) Moon. The paper provides the diversity and distribution of Clerodendrum species in Northeast India with special reference to Barnadi Wildlife Sanctuary, Assam along with their phytogeographical affinities in rest part of India and neighbouring countries. The correct nomenclature of each species, brief description, ethnobotanical uses of the available species, photo plates and other relevant notes are also highlighted.

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
Any comments/ corrections are welcome.

If you find any mis-identification, pl. let us know.
If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
