Below you can see that the first pair of leaves in Moringa longituba have three leaflets.
Most tree moringas grow like crazy in height after germination. Not M. longituba. This species lives in an area with very little rain, which falls in two very short seasons. So when water is present, the plants sprout quickly, grow two or three leaves, and invest all the rest of their energies into growing a tuber. The leaves are short lived, and the plants die back to the tuber, riding out the dry season until the next rains fall.
Let's wish these little guys well.
