Daphnogene polymorpha (A.BRAUN) ETTINGSH., 1851 Pl. 2, Fig. 9
M a t e r i a l. A single leaf impression from layer GLA30
(MGPT-PU141016).
D e s c r i p t i o n. Rather complete simple leaf except missing apex, shape elliptic to slightly obovate, petiole not preserved, base shape slightly convex, base angle obtuse, l × w about 60 × 30 mm, ratio l/w about 2; margin entire, venation suprabasal acrodromous, the basal secondaries running into the apical part of the leaf, next pair of secondaries only in the apical part of the lamina, secondaries brochidodromous; tertiaries hardly visible.
R e m a r k s. The well-preserved basal secondaries that reach into the apical part of the leaf are characteristic. In Ocotea the basal secondaries are shorter and less strong.
