So it is, as I have myself observed, with some dimorphic plants.
The occurrence of dimorphic and non-dimorphic species in the same genus is quite the same as I find in Linum.
The two basal blooms are dissimilar or dimorphic both in shape and colour, being tawny yellow spotted with purple.
Hottonia is dimorphic, with pollen of very different sizes in the two forms.
Dimorphic flowers are frequent, as in the bog-bean (Menyanthes).
