Bumbo.— Plentiful in very cold rivulets and springs at Arreial de 

 Caionda, and observed elsewhere throughout this region ; on the

 in the Fonte de Caionda at an elevation of 4000 ft. ; Oct. 1859, also

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.
