Locality
From Hollick (1930) (p. 78-79)
"Yukon River, north bank, about 12 miles below Melozi telegraph station (original No. 20); collected by W. W. Atwood and H. M. Eakin in 1907 (lot 4634)."
Description
From Hollick (1930) (p. 78-79)
"Leaves subpeltate with broad cordate bases; nervation palmate, consisting of a straight midrib, a major pair of spreading lateral primaries and two pairs of minor ones below, all radiating from the pelta at the base of the leaf; secondary nerves widely spaced on the midrib."
Remarks
From Hollick (1930) (p. 78-79)
"These leaves are too fragmentary for accurate description or comparison. They are apparently, however, of the same general specific type as Menispermites acutilobus Lesquereux (1883) (p. 78, pl. 14, fig. 2) from the Dakota sandstone of Kansas; and they are strikingly similar, so far as the basilar characters are concerned, to a specimen from the Magothy formation of Marthas Vineyard, Mass., referred provisionally to Lesquereux's
species (Hollick 1906) (p. 62, pl. 12, fig. 8)"
