That is great to have this available to see. With most Taxonomists, Adenium being the Genus, obesum being the species. The swazicum, boehmianum, arabicum, TS' are all sub-species of the Adenium 'obesum' and not considered a species of their own.

This is a topic that I have run into in other sites and overall, most consider the above mentioned Species (swazicum, boehmianum, etc.) to be individual species based on their native origin.

Not something I have been interested in getting into a debate over.

Thank you, Agartta for posting this.
