www.camels-camels.com informs me the scientific name for the Dromedary (one humped) camel is Camelus dromedarius. www.llamapaedia.com tells me the scientific name for a llama is Lama glama. The NCBI's taxonomy database tells me the camel and llama are cousins. If you're confused, you missed the vital conversation at the last social meet.
