Rh. pholidotum is like Rh. secithin: but the puberulous 
bases of the exserted style and stamens of that species are very 
different. Its nearest ally is perhaps Rh. brevistylum. There 
should be no danger of confusion of Rh. pholidotum with any 
other species in the Heliolepis series (see p. 113). Apart from 
flower-colour distinction, it wants the viscid upper-leaf surface 
and the hairs outside the corolla of Rh. oporinum; it has not 
the narrow-based leaves of Rh. brevistylum ; it has not the large 
leaves and distantly placed scales of Rh. heliolepis ; the size of 
leaf as well as the small campanulate—not tubular-campanulate 
—corolla tell it at once from Rh. plebeium; Rh. fumidum has a 
green spotted corolla, a calyx epilose outside and an epilose 
ovary ; Rh. rubiginosum has conspicuously biform under-leaf 
scales. It is the Middle West Yunnan (Tali) representative of 
the series, and is in cultivation.
