The two Chinese varieties are rather poorly differentiated; however, there does appear to be a good correlation within the material available between flower color and flower size. Plants with white corollas have tubes less than 3 mm, whereas those with yellow corollas or yellow marked with brown have tubes 2.4–4 mm. This distinction merits further investigation.
