Type

Original diagnosis/description

Endocarp unilocular, nearly circular in lateral view, with a rounded apex and base. Primary vascular strand entering the locule subapi-
cally. Endocarp surface ornamented with narrow, broadly spaced pits, corresponding to broad tubercles protruding shallowly into the locule cavity. Endocarp wall notably thick (ca. 1.4 mm), at least along the dorsoventral margin. Endocarp ca. 21.5 mm in length, ca. 19.6 mm in width.

Etymology

The generic name, ‘Manchesteria’, is established in recognition of the extensive contributions of Steven R. Manchester to the field of palaeobotany over many years of research, including his invaluable guidance and generosity as a mentor, colleague, and collaborator.
