- Diagnosis
- Fronds at least bipinnate inferring from the inequilateral base of the pinnules, variable in size, somewhat coriaceous in texture. Pinnules ovate, with an acuminate apex and a rounded inequilateral base. Margins entire, regular in the limited amount of material seen. Length ranging from 5 to 15 em. Maximum width, below the middle, ranging from 1 to 4 em. Midvein stout, channeled above and prominent on the under side. Laterals thin but well marked, regularly and closely spaced, subparallel; they diverge from the midvein at acute angles, curving rapidly outward, and pursue nearly straight
courses to the margins. In the larger specimens their general angle of divergence from the midvein is about 80°. In the smaller specimens they are more ascending. They are invariably once forked and rarely show a second
dichotomy. The forking is usually near the base but there is considerable variation in this feature, frequently the fork is quite a distance above the base, and more rarely it is half way to the margin.
