Taxonomy

Scaevola glandulifera was first described in 1839 by Augustin Pyramus de Candolle in Prodromus Systematis Naturalis Regni Vegetabilis.[1][2]

Etymology

The genus name, Scaevola, is Latin, a diminutive of scaeva, the left-handed, referring to the left-handed Roman, Gaius Mucius Scaevola, made famous by Livy, the flower being so like a hand.[6] The specific epithet, glandulifera, comes from the Latin, glandula (gland) and ferre (carry/bear), giving "gland-bearing".[7]
