Yes it is... and to be honest, I really love that narrow pagoda-shape a lot. Similar to spicerianum, parishii... I personally always prefer "pagoda-shape" above "flat pancake" dorsals on these type species.
There is a term that judges use when describing that “little green knob” in the center of a staminode. It is called “the BOSS”. Yes, the boss!
Naturally the ‘boss’ could be any color but that is the term that we now use.
I wonder if that will ever catch on?
I belief umbo is the correct name for that "knob" ( link to Kew reference )
But as long we all know what is meant, I am ok with calling it knob, boss, warts, button...
And yes, I like the green umbo as well
