I have one plant of each and they both happen to be in bloom. The
D. Binata is on its last few remaining flowers, and the D. Capensis
has just started on three flowers.
Forgive my fuzzy memory of proper biological terms. The procedure
I'll try is to remove the stamen of one flower and brush its
anther against the stigma of the other flower. I recall it is
preferable to use the anther of the flower with the larger
stigma-to-ovary distance, to brush onto the flower with the
shorter corresponding distance. The flowers of both plants
are small enough so that I cannot tell if the stigma-to-ovary
distance of each is very different.
Robert Allen made a few remarks in response to a private e-mail,
saying that a knowledge of each plant's chromosomal structure
is necessary to predict whether they can hybridize with each other.
Does anyone know, by experience or otherwise, whether these
plants can be interbred? If they can, then my imagination tells
me the offspring could be one helluva Drosera!
Thanks!
