Leaves with petiole, 4-7(-9) cm long, sheathing the young shoots, petiolar margins membranaceous, translucid, extending through 2/3 of the petiole, glabrous or minutely pubescent, with lustrose appearance; leaf blades (13-)15-27(-45) cm long, 12-21(-26) cm wide, dimorphic through the sympodial axis, monopodial leaves ovate or widely ovate, cordate
and slightly auriculate at the base, with the lobes almost symmetrical; sympodial leaves elliptic-ovate, cordate
to deeply auriculate at the base, with the lobes asymmetrical, the bigger lobe half or completely overlapping the petiole; obtuse to shortly acuminate at the apex, ciliate at the margin, minutely pubescent in both surfaces; pinnately nerved, veins 4-8, inconspicuously punctate pellucid; membranaceous, with a matt appearance.
The explanation for the existence of these odd morphologies that coexist with typical cordate
individuals could be caused by several factors.

. Renates are creatures that have kidneys, and cordates
[20.] The botanical species that we studied include: lima bean seedlings; the heavy cordate
vine Aristolochia macrophylla (Dutchman's Pipe); Swedish ivy; Mimosa pudica L.; and cactus.
Whitten, known experimentally as DRC96-1, was selected for (i) cordate
leaf base with shallow lobing and serrated margins, (ii) plant height, a gross indicator of yield (Wilson and Joyner, 1969; Higgins, 1974), (iii) resistance to powdery mildew [caused by Leveillula taurica (Lev.) Arn.], and (iv) delayed flowering.
, longer than wide, shortly to strongly pointed between coxae 4 (Figs.
The pinnule base is cordate
, or stalked, and the margin entire.
. This is a heart-shaped leaf with the length slightly greater than the width.
While Nymphaea is known from leaves and rhizomes from Sonoma, California; Trapper Creek and Weiser, Idaho; Buffalo Canyon, Eastgate, Esmeralda, and Middlegare, Nevada; and Mascall, Stinking W ater, Succor Creek, and Trout Creek, Oregon It is distinguished by oval leaf scars along the rhizomes and cordate
or offcentered peltare, orbicular to ovate leaves, with a faint midrib and weakly pinnate to radial venation.
Rhizome (underground stem) globose-bulbous; leaf blades deltate to cordate
