In Dr. Dimmitt's section of the new book he states
that there are as yet no recorded hybrids between Adenium crispum and
A. swazicum. Whilst my new seedling of Dance of Butterfly,
seedling #2 and A. swazicum #10, is not a primary hybrid, it is

from Mr. Ko's seeds labelled 'Dance of Butterfly'. From its leaves you can
tell that it is at least 50% A. crispum and possibly

The pollen parent A. swazicum
seedling #10 was a sibling cross of the very dark
A.swazicum 'Boyce Thompson' and A. swazicum MAD #86
raised from Dr. Dimmitt's seeds:
Here is the result, the flower is bigger than the
pod parent but interestingly the crispum leaves have again been
dominant:
and here is the little seedling:
