Orbea laticorona       (M. G. Gilbert) Bruyns

Small succulent forming diffuse mats, not rhizomatous. Stems 5-15 cm long, 0.8-1 cm in diameter (excluding teeth), decumbent, grey-green mottled with purple-brown; tubercles 5-13 mm long, arranged into 4 rows along stem, ascending, conical, attenuated into very fine tips, without stipular denticles. Orbea laticorona differs from 0.sprengeri in its broader outer corona and longer inner corona lobes. The two species are undoubtedly closely related, and Gilbert (1978) originally treated 0. laticorona as a subspecies of 0. sprengeri.

DISTRIBUTION: Ethiopia, Sudan; 1400-2000 m
