P. Goubet et al. 2000 | Pinnules are large, elngated and cordate; the apex is usually roundly acute. Venation is course with a well marked midvein. Secondary veins fork twice, and sometimes a third time near the margin. N. biformis is abundant in Alabama, but does not show large morphological variability. |
