Developmental and Structural Section Seago, James [1]. Adaptations of the aquatic plant, Rorippa officinale, to its stream habitat in summer and winter. The aquatic plant, Rorippa officinale, is well adapted to its habitat in a small stream where it flourishes in spring, summer, and fall, and remains anchored and vital even in the winter conditions of a snow belt in Oswego County, New York. The extensively branched plants have adventitious roots that are produced at most nodes, both in and above the flowing water; the aerial roots elongate very little. Roots and stems generally have characteristic brassicaceous structures. Submersed adventitious roots have an aerenchymatous cortex with a simple endodermis. Submersed parts of stems have a cell layer surrounding the central core of vascular budnles, ring of fibers, and pith; this layer is endodermal-like and more prominent in submersed stems than in aerial stems. There are larger air spaces and less chlorophyllous tissue in submersed stems than in aerial stems.
