"Locust trees are species of Robinia and Gleditsia"

They are two completely different trees. The vessels in the Robinia which
was named after the first arborist, Robin (sic?), are arranged in a ring
porous fashion. E.g., Oak, American Elm.

Gleditsia has vessels diffused such as in maples, birches, beeches and so
on.

So, first thing to establish to answer your question, is are you referring
to black locust or honey locust as far as comparing them to acacia.

There is a picture of wood in a cross section of honey locust here "Woody
Root / Woody Stem"

The black locust, robinia is similar with respect to vessels as that of
oak.

I have not dissected a acacia. If you could send me a woody stem sample I
will prepare it and place it under the microscope and see what wood type
it is. That can reveal a lot about the tree and its water requirements.
