I will be putting up a full article about the dragon-trees
Dracaena or
Draco (Asparagaceae) in a few months time. While researching that, I accidentally collected a list of plants whose generic names had a reference to dragons. I thought I might as well write them up for no real reason. I have ignored all those that are not currently accepted, and those with dragon-related species names and common names as they are as common as snapdragons. Nothing special to see here, just an aggregated list of stuff I looked up illustrated with other people's photos.
Dracocephalum (Lamiaceae) - dragon-head.
The type specimen
Dracocephalum moldavica was named by Linnaeus in 1753. An Asian annual of the mint family. It has large flowers fancied to resemble dragon's heads. It, and other members of the genus, have been called dragon's head. The first time this English name appeared in print was also in 1753 in
Chamber's Cyclopaedia.
Dracocephalum moldavica, Gorynych variety.
