Description

From Hollick (1930) (p. 65)

"Plate 34, ,Figures, 2 - 4"

"Leaves petiolate, triangular ovate, somewhat asymmetric, with a broad, lightly curved, truncate base and an obtuse, oblique apex; margin dentate; nervation pinnate-tripalmate, craspedodrome; midrib straight; secondary nerves four on each side, subopposite, leaving the midrib at acute angles of divergence, slightly upward curved at the extremities; lateral primaries opposite, suprabasilar, branched on the under sides, one somewhat longer, straighter, and more ascending than the other."

 

Remarks

From Hollick (1930) (p. 65)

"This species has an outline similar to that of Populites lancastriensis (Lesquereux) Lesquereux (1974; 1893) (p. 58, pl. 3, fig. 1; p. 12, pl. A, fig. 4 [=Populus lancastriensis Lesquereux, Am. Jour. Sci., 2d ser., vol. 46, p. 93, 1868]) from the western United States, especially to Lesquereux's Figure 4, Plate A; but ours is more expanded at the base and has a dentate margin. The asymmetry of our species is also a distinguishing feature. The apex is oblique. The secondaries subtend more acute angles with the midrib on one side than on the other, and the basal portion of the leaf on that side is more extended laterally than on the other. These characters give the appearance that is suggestive of the genus Vitus."
