I think it's branching. I'll check for sure when I get home later today. I finally have two plants flowering at the same time again, and one of the B. guehoi "A" is picking up again. I wasn't giving them enough water. I still have a couple seed of "A" and "B" maybe I'll try again now that the weather is warming up. I only have one plant each of "A" and "B" still alive.
The hybrids currently flowering are not branching. They may in the future. The previously flowering hybrids branched.
