Notes. This new species can be distinguished from Oreocharis magnidens by the purple 
base of the white corolla lobes (vs white base of purple corolla lobes), corolla tube 
throat not constricted (vs constricted throat), and coherent anthers (vs free anthers). 
It is also similar to Oreocharis curvituba but differs mainly in the colour pattern and 
shape of the corolla (Wei et al., 2016). Table 2 details the differences between these 
species.
