When grazed, Seddera latifolia forms compact, intricate ‘spiny’ cushions (although the plant does notin fact possess spines). Ungrazed plants are moreherbaceous. S. spinescens is only a depauperate form ofthe widespread S. latifolia growing widely on the coast of Eritrea and Somalia; the name has also been applied to similar plants from the Hadramaut regionof southern Yemen. The branches in most cases havebeen heavily grazed. In all other characters except size, S. spinescens fits very well with S. latifolia, so thename is considered a synonym of the latter here.
