Backcrossing the natural hybrid C. "23-7" reveals that the offspring
immediately split into the well known C. walkeri, C. beckettii and the original plant, the most simple
Mendelean picture. So, this natural C. "23-7" plant can be interpreted
as a hybrid between C. walkeri and C. beckettii.
When the C. "23-7" plant is crossed with C.
parva you will get in the offspring the well known C. ×willisii including (syn.) C. lucens. Probably most crossings in which C. parva is involved will give 'look alike'
plants.
Like C. parva, C. nevillii is probably a 'pure'
species, and for that reason a preferable parent. Look at the marvelous crossings with the
latter.
See the pages on the common Sri Lankean species for other deviating forms.
