- Diagnosis
- Fertile branches with terminal ovules dichotomous at 30°–125° and 0.3–0.8 mm wide. Ovules smooth, 7.0–13.2 mm long and 3.0–5.7 mm wide. Integumentary lobes 0.7–1.8 mm wide and their width slightly decreasing toward the top and bottom of the ovule. Gap between two adjacent lobes 0.4–0.8 mm wide. Integumentary lobes with massive parenchyma cells that are polygonal or rounded in outline. Nucelli smooth, with rounded tip, 4.8–6.0 mm long and 0.9–2.0 mm wide. Nucelli narrower at the two ends and slightly wider in the middle part.
