Abstract
As part of a revised generic classification of Aloe Linnaeus (1753: 319) sensu lato (Grace et al. 2013), Aloidendron (Berger 1905: 56) Klopper & Gideon F.Sm. in Grace et al. (2013: 9) was established to accommodate six tree aloe species that Berger (1905) previously placed in two sections, Aloe sect. Aloidendron Berger (1905: 56) and A. sect. Dracoaloë Berger (1905: 56). The six species transferred to Aloidendron were: A. barberae (Dyer 1874: 566) Klopper & Gideon F. Sm. in Grace et al. (2013: 9), A. dichotomum (Masson 1776: 310) Klopper & Gideon F.Sm. in Grace et al. (2013: 9), A. eminens (Reynolds & Bally 1958: 187) Klopper & Gideon F.Sm. in Grace et al. (2013: 9), A. pillansii (Guthrie 1928: 15) Klopper & Gideon F.Sm. in Grace et al. (2013: 9), A. ramosissimum (Pillans 1939: 66) Klopper & Gideon F.Sm. in Grace et al. (2013: 9), and A. tongaense (Van Jaarsveld 2010: 71) Klopper & Gideon F.Sm. in Grace et al. (2013: 10). These tree aloes, but not A. sabaeum (Schweinf.) Boatwr. & J.C.Manning in Manning et al. (2014: 67) (see next paragraph), have been treated by Van Jaarsveld & Judd (2015).
