Ovule and seed of Zanthophyllum (Polygalaceae)
The ovule primordia of Xanthophyllum are trizonate and the outer integument is completely of subdermal origin. Due to a different post-fertilization development the variation in seed coat morphology is considerable. Primitive features of the Xanthophyllum seed are thick endosperm with foliaceous cotyledons, a well-developed palisade layer and a thick mesophyll layer.
