Robust form with more numerous pinnules and larger plants than typical. Under Quercus stellata, Q. shumardii, & Juniperus virginiana in the Eastern Cross Timbers of Grayson County, TX.
Blades sparsely dissected, the terminal pinnae margins nearly parallel, apices rather blunt and divisions notably wide, blades deep green during winter.

Advice needed. Growing along a stream for dozens of feet. Doesn't appear to be any of the TX aquatic invasives. Water was about about 1-3 inches deep. Leaves ranged in size from dimes to silver dollars. Unsure if roots were attached or free floating.
