Summary
Subsequent to the treatment of the Aloaceae, with 38 species of Aloe, in the Flora of Ethiopia (Sebsebe Demissew & Gilbert 1997), four more species, Aloe bertemariae Sebsebe & Dioli (2000), A. friisii Sebsebe & M. G. Gilbert (2000), A. clarkei L. E. Newton (2002) and A. elkerriana Dioli & T. A. McCoy (2007) have been described from that country. Here four additional new species are described: Aloe benishangulana Sebsebe & Tesfaye from near Assosa, Benishangul-Gumuz in Welega floristic region; A. ghibensis Sebsebe & Friis from the Ghibe Gorge, Kefa floristic region; A. weloensis Sebsebe from near Dessie in Welo floristic region and A. welmelensis Sebsebe & Nordal along the Welmel River in Bale floristic region. The phytogeographical positions of the new species are assessed by comparison with the previously known species. Complications with the deposition of type material of A. clarkei and A. elkerriana is used to raise various issues regarding the ethics of describing new taxa from foreign countries.
