Note: Paratypes: S 174048, S 174049, S 174050–S 174058 (IAA 2/95, Marsupial site).
Seeds small, anatropous, bitegmic and exotestal, ovoid to ellipsoid, with rounded chalazal end and slightly pointed micropylar end. Lateral raphe indistinct on seed surface, distinct internally, extending in mesotesta from the hilar scar at the germination cap to the chalazal end of the seed. Germination cap with micropyle opening slightly raised and distinct shallow hilar scar close to micropyle. Micropyle and hilum separated by narrow zone of exotestal cells. Exotesta of one layer of high, palisade-shaped sclerenchyma cells with thick cell walls leaving a narrow, elongate lumen; anticlinal walls straight without undulations; facets on outer surface polygonal (pentagonal to hexagonal). Mesotesta of thin-walled parenchyma cells, few cell layers deep, thicker along the raphe and at chalazal and micropylar ends. Seed surface smooth with faint polygonal outlines of the exotestal cells.
From the continent where the fossil seeds were discovered.
