  • This plant was first named Michelia wilsonii in1906 to honor the renowned botanist and Asian plant explorer Ernest (“China”) Wilson (1876-1930).  The genus Michelia was first named by Linnaeus in 1753, but because of DNA sequencing and other research, michelia are now combined with Magnolia.  However, an other magnolia had already been named Magnolia wilsonii to honor Ernest Wilson, so a different name was required.  The solution was to use Wilson’s first name; hence the Latin name of this plant is now Magnolia ernestii.  Wilson is possibly the only botanist to have two plants in the same genus named after him.
