Plant Physiology

I am interested in learning about the difference between lotus stems and ludwigia repens

Can anyone provide a reference?

I'm asking since lotus/water lilies seems to be in a list of minority plants that has only one surface leaf per stem instead of developing multiples per stem

It is not physiology question. It is more of plant anatomy. Each leaf consists of the blade and petiole. Each leaf of Ludwigia has a very short petiole, which connects the blade and the stem. What you are calling stem in Lotus is actually petiole.

Lotus plants are "designed" to get their CO2 by putting leaves flat on the water surface. Many aquatic plants are "designed" to obtain CO2 either from dissolved CO2 in the water or from leaves at or above the water surface. The carpet type plants just get theirs from the water, so they usually need lots of CO2 dissolved in the water.
