Taxonomy and morphological diversity of infructescences Jenkinsella co-occurred with Trochodendroides leaves in the Cretaceous and Paleogene [2017]

Diagnosis

The long shoots bear alternate lateral racemose infructescences 22—25 mm apart. Distinct leaf scar is visible under the base of raceme. Racemes are 20—25 mm long and about 10 mm wide, formed by more than 20 spirally arranged closely spaced follicles. The follicles are borne on very short stalks, mostly singly. They are widely elliptical in outline, suborbicular in transverse section, small, 5—6 mm long, 3—3,5 mm in diameter, with slightly attenuate short style and obtuse base. Ventral sutures of follicles oriented in different directions.
