The elusive Mr Green and the eponymy of Aloe greenii Green ex Rob. and A. viridiana Gideon F.Sm. & Figueiredo (Asphodelaceae: Alooideae)

To date the eponymy of the name Aloe greenii Green ex Rob., and by implication that of the name A. viridiana Gideon F.Sm. & Figueiredo (Asphodelaceae: Alooideae), which was recently published to replace the name A. greenii Baker (1880) non Green ex Rob. (1875a), has been open to speculation. We show that these names in all likelihood commemorate Mr Charles Green (c. 1826–1886), who at one time was the head gardener of Mr William W. Saunders' well-known succulent plant collection at Reigate, Surrey, United Kingdom.
