Bowkeria is a small genus of shrubby plants inhabiting 
the eastern region of Cape Colony, and extending northward 
to Natal and the Transvaal. Most nearly allied to Ixianthes 
and Scrophularia, the species resemble in habit, foliage and 
the shape of the flowers some of the shrubby Calceolarias. 
Of the five species known, that here figured is the only 
one in cultivation, assuming that none of the plants grown 
under the name of B. triphylla is correctly designated. 
Plants bearing this name have been cultivated in the 
Temperate House, Kew, for many years, but as yet no 
flowers have been produced, in the absence of which a 
satisfactory determination of the species cannot be 
attempted. In foliage B. gerrardiana and B. triphylla are 
practically identical. The latter is, however, easily dis- 
tinguished by the shape of the upper lip of the corolla, 
being very much narrower. The difference in the bases 
of the filaments is a less important character.
