Description

From Hollick (1930) (p. 78)

"Plate 40 Figure 4"

"Leaf symmetrical, narrowly flabelliform, 4.5 centimeters in length by 4.2 centimeters in maximum width just above the middle, upper part rounded, lower part cuneate, tapering to a wedge-shaped base; margin obscurely crenate above the middle, entire below, nervation flabellate, consisting of a midrib and three lateral primaries on each side, the outer pair relatively weak; secondaries ascending at acute angles of divergence, simulating forking of the primaries, the upper ones branched or forked in a similar manner and extending to the marginal crenations."

 

Remarks

From Hollick (1930) (p. 78)

"The reference of this specimen to the genus Nymphaeites may be regarded as open to question but that it belongs in the Nymphaeaceae is too strongly indicated to be ignored, and all the foliar features characteristic of the genus, as described and figured by Heer, are represented in it. In our specimen the midrib is straight and without secondaries for approximately the lower two-thirds of its length; and a suggestion of a midrib may be seen in the erect, perpendicular primary depicted by Heer (1870) (pl. 14, fig. 10). If our generic reference is correct our species is apparently older than any representative of the genus heretofore recorded."
