The genus Streptocarpus is confined to Africa south of 
the Tropic of Cancer and to the Mascarenes. Two sections 
are generally recognized ; one, Unifoliatae, has only one 
green assimilating leaf which is a persistent cotyledon ; 
the other, Aosulatae, has 1-4 leaves in addition to the 
cotyledon which is usually present. The species figured 
is one of the Unifoliatae, of which about fifteen are 
already known from various parts of South Africa. The 
nearly or quite glabrous leaf (cotyledon) of S. denticulata 
is unlike the densely hairy one of S. pusilla, Harv., 
to which our plant appears most nearly allied. The 
glandular-pubescent character of the inflorescence is a 
noticeable feature, though our species shares this with 
some of the others. The general colour of the flowers 
is distinctive, and may be described as rose-purple with 
lines of deeper carmine on the lower lip, and dark- 
purple blotches on the lower part of the upper lip. 
In other species of Streptocarpus figured in this work 
the corolla is more or less blue or violet, as, in S.
