Locality Map



From Hollick (1930) (p. 83)

"Leaf obovate, inequilateral, entire, 6 centimeters in length by 3.75 centimeters in maximum width, rounded above to a broad, curved summit and below to a curved, wedge-shaped base, triple-nerved, apparently from close to the base; lateral primaries diverging from the midrib at acute angles, curving inward and extending close to the margin in the upper part of the leaf blade, where they thin out and apparently connect with and merge into fine secondary nerves from each side of the midrib."



From Hollick (1930) (p. 83)

"Critical diagnostic characters in this leaf are either obscure or entirely lacking. The basal portion is missing, hence it is impossible to determine definitely whether the lateral primaries are basilar or supra-basilar. The apex was apparently abruptly apiculate. It is suggestive of certain of the forms of Cinnamomum buchi Heer (1856) (p. 90, pl. 95, figs. 1-8) but this is a strictly Tertiary species, and, in any event, the critical characters in our specimen are too poorly preserved for satisfactory comparison. It is possible, in fact, that the generic reference may be questioned, and that some other genus - Paliurus, Ceanothus, or Zizyphus - might be considered equally applicable."
