Welwitsch paid much attention to this species. He considered that 
it differs from 0. Julianum, which is common in Portugal, only in its 
somewhat more acute leaves, with nerve usually vanishing at two- 
thirds the leaf's length and not just below the apex, and in its rather 
larger capsule. The African plant has its older stems compressed, 
almost complanate, nigrescent. He observed the operculum of several 
capsules to be not conical but depresso-hemispherical, its rostrum 
becoming more equally cylindrical and not conical at the base ; but 
after examining more than twenty capsules in different stages of ripen- 
ing, he was constrained to modify his view as to this variation of form 
or proportion, the normal operculum being formed almost or indeed 
exactly as in 0. Julianum.
