meters, Jan. (1897), Schlechter, 10049! district Worcester; on the 

 Matroosberg, 1,950 meters, Jan., A. Bolus (in herb. Bolus, 6359 !) (in 

 herbb. Kew, Schlechter, Bolus, &c.). 



A very distinct species, in floral structure nearest to H. auricidatum 

 Less., next to which it may be placed. The heads are nearly as 

 large as in that, but the leaves very different. These latter are of 

 somewhat unusual shape : the petiole-like lower portion being 

 broadish, and then more or less suddenly dilated into an obcordate 

 or subreniform blade, more resembling those of H. excisum Less.^ 

 than those of any other known to me. The plant is probably con- 

 fined to the higher mountain-ranges of the western part of the 

 Colony.
