Description

From Hollick (1930) (p. 52)

"Plate 2, Figure 9"

"Foliaceous organ, resmbling a bract, phyllode, or stipule, obliquely orbiculate-cordate, entire, traversed by numerous fine, dichotomously branching veins that radiate from the base."

 

Remarks

From Hollick (1930) (p. 52)

"This well-defined specimen is referred to the genus Phyllocladites because of its apparent generic relationship to Phyllocladites rotundifolius Heer (1874) p. 124, pl. 35, figs. 17 - 21b) from the Cretaceous of Svalbard, which he regards as representing the leaf-like organs or phyllodes of a coniferous tree related to Phyllocladus; but whether or not this reflects the correct morphologic nature and systematic position of our specimen may be considered an open question. The nervation is so delicate that it is difficult to define accurately. There is an obscure indication of a midrib, and this, as well as each of the other veins, occasionally forks by successively finer and shorter branches that ultimately terminate in the margin. So far as can be discerned there is nowhere any indication of reticulation, otherwise it might be compared with Proteaephyllum orbiculare Fontaine (1889) (p. 283, pl. 139, fig. 4) to which it bears a very close surficial resemblance."
