Tropicals & Tender Perennials: aborted callous tissue and embryo, 0 by EricKnight

As you can see, this is what I expected to find from an aborted embryo attempt as compatible pollen allowed the pod to mature. The black embryo's were all halted in growth and extra callous tissue formed creating these structures. We can only be hopeful that a few will not form so much callous tissue in future seed pods or that a few seeds will go undetected and be allowed to grow to a state whereby they are mature enough to make it without tissue culture.
The formation of ovular tumors in fertilized ovules prevents hybridization in incompatible species crosses of Datura.
