Aloe succotrina, a Western Cape aloe, growing on fynbos mountain slopes and close to the sea from the Cape Peninsula to Mossel Bay, was named after the Yemen island of Socotra off the Horn of Africa. This happened because the plant's origin was thought to have been there.
This was the first aloe believed to have been grown in Europe, with a recorded flowering in Amsterdam during 1689. The correction in the literature dates back only to 1906 (www.plantzafrica.com), but such errors tend not to cause name changes or corrections, as the oldest written record is the one that is kept.
Socotra itself has fame as the endemic home of more than two hundred interesting or remarkable plant species, including some aloes used for medicinal and cosmetic purposes. Although this aloe does not deserve the name, it serves to remind of early human involvement with mastering plant knowledge; and of the botanical significance of the rarely visited island of Socotra.
There is, for instance, the dragon blood tree on Socotra, Dracaena cinnabari, an umbrella shaped tree with red sap that had been used in olden times as a dye and medicine, but even today is used as a varnish and paint.
According to Chung Ki Sung in his PhD dissertation in the School of Pharmacy at Chonnam National University, Alexander the Great conquered Socotra to obtain aloe medicines there for the treatment of his soldiers (Wikipedia).
