Corolla said to be " pale-mauve to white " {Perry). This species is near 

 B. Candida, which has entire calyx-segments. The capsule is not half the size of that 

 of ^. acanthoides, the inflorescence and toothed calyx-segments are quite unlike, the 

 capsule is only 2 seeded. But the species nevertheless appears on the whole more 

 allied to B. acanthoides than to the subgenus Prionitis. 



14. B. grandicalyx, Lindau in Engl. Jahrh. xx. 25. Branches up 

 to 1 ft. long, hispid. Leaves up to 2 by 1 in., tip obtuse-triangular, base 

 narrowed, with short w^hite and long 1 -celled tawny hairs ; petiole ^ in. 

 long ; interpetiolar spines J in. long, simple, hairy, straight or curved 

 near the top. Flowers solitary ; bracts J in. long, as simple spines, hairy. 

 Posticous sepal J by J in., coarsely spinous-toothed in the upper half. 

 Corolla oblique, hardly 2-lipped, pale blue; tube | in. long, slightly 

 widened upwards. Ovary glabrous, tip minutely hairy ; ovules 2, 

 subsimilar in each cell.

The differences between B. grandicalyx and its var. are greater than those 

 between some species hereabout. This plant is very near, and has been regarded as 

 equal to B. Oueinzii, Sonder, from Natal ; which differs by having the leaves 

 rounded at the base. In the Ang( 

 length of the outer, lanceolate-linear.
