Aloe ×gemmelliae (Asphodelaceae subfam. Alooideae), a new natural hybrid between A. broomii and A. grandidentata from the southwestern Free State province, South Africa

Although most species of Aloe Linnaeus (1753: 319) flower in winter, the comparatively few taxa of this genus that occur naturally above South Africa’s climatically severe Great Escarpment tend to flower during spring when temperatures are on the increase. Two such species are A. broomii Schönland (1907: 137) and A. grandidentata Salm-Dyck (1822: 3 [species no. 2]).
