http://en.wikipedia.org/wiki/Sagittaria The generic name means "belonging to an arrow" in Latin and refers to the shape of the leaves.

im pretty sure the author used katniss because, as said above, the generic name means "belonging to an arrow" and katniss always uses archery and stuff. its also latin, which a majority of the names are based off of.
