Neuralethopteris biformis

- Neuropteridae

Neuralethopteris biformis was named by Lesquereux (1880) [Holotype: Neuropteris biformis. Lesquereux considered N. biformis and N. elrodii to be conspecific. However, N. elrodii should be assigned to N. schlehanii.].

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

P. Goubet et al. 2000Pinnules 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.
