First comes a fan leaf. A
Next, a cola banch will spring from the crotch.
C -could show a mainstem or cola branch, it illustrates that EVERY cola branch will always have a supporting fan/shade/water leaf. Always.

Regard the green lines I put in your photo's.
These are fans.

Hard to see on the right,,,the white and black lines, those are cola branches.
On the left upper,,,we have only fans. Next come branches.
I cannot exactly tell, in (journal) post #41, if I am looking at a mainstem or branch,,,regardless, you will see branches spring from those fans,,, before genitals.
Am I talking sense ?
