Pollen grains present within pollen chamber, elliptical, 50 \xm long, monocolpate. Material and occurrence. , Fig. 20A-C, a compressed ovule retrieved following maceration of an isolated leaf fragment of Ginkgoites weathem'axiae, is the only specimen to have been found at present. It is from the plant debris beds of Worbarrow Bay, Dorset. Wessex Formation; Hauterivian. Discussion. Interpretation of this structure, the only reproductive body to have been associated with ginkgoalean material from the English Wealden to date, is difficult, particularly as there is only a single compressed specimen (Figs 20A-G; 21) available for study. However, the general morphology (Fig. 20A-C) is clearly that of an orthotropous gymnosperm ovule. The ovule was found in so close an association with a leaf.
