Pazliopsis undertemined E. M. FRIIS, P. R. CRANE et K. R. PEDERSEN 2018
Description
Pazliopsis sp.
Text-fig. 48g, h
Description and remarks. The material comprises several small, isolated, bilaterally symmetrical seeds that are about 0.85 mm long, and 0.75 mm broad in the dorsi-ventral direction (Text-fig. 48g). The seeds are anatropous and bitegmic. They are elliptical to almost circular in outline, rounded at the chalazal end and truncate at the micropylar end. The hilar scar is almost circular in outline and lacks a hilar rim. The outer epidermis of the outer integument consists of palisade-shaped cells with thickened wavy anticlinal walls that result in a jigsaw-puzzle like surface pattern (Text-fig. 48h). The inner integument is membranous.
Affinity and other occurrences. The seeds described here closely resemble seeds of Pazliopsis reyi E. M. FRIIS, P. R. CRANE et K. R.PEDERSEN from the Torres Vedras mesofossil flora in shape, surface ornamentation and seed coat anatomy (Friis et al. 2018c, 2019a). However, the seeds from Catefica are larger and the hilar scar is not as pronounced as in the seeds from Torres Vedras. The Catefica seeds are also circular rather than elongate-ovate. Pazliopsis reyi is thought to be related to members of extant Austrobaileyales and Nymphaeales (Friis at al. 2018c).
