- Diagnosis
- Frond probably bipinnate; frond or penultimate pinna large, possibly reaching more than 30 cm. in length; its axis thin, about 2mm. across, bearing laminae in one plane with the ultimate pinnae and on both sides of the axis, the lamina on each side being 10 mm. broad, deeply lobed into about 10 lobes with ro"nd . apices and at a right angle to the axis of the penultimate pinna. Ultimate pinnae more than 6cm. Iong, 3cm. broad, subopposite, remotely attached, the distanee being about 4.5cm., and at a right aiigle to the axis. Axis of the ultimate pinnae also thin, being 1 mm. across. Pinnules 1.5-2 cm. iong and O.5-O.8crn. ' broad, narrowing towards obtuse apices, subopposite, set closely, apd fused Iaterally at the base; margin of pinnules usually undulating, - Basal pinnules in each ultimate pinna reduced to mere lobes and merged into laminae on the axis of penultimate pinna. Nervation distinct, standing out elearly as relief. Midnerve of the pinnules is almost at a right angle to the pinnae-axis, straight and persists to the tip of pinnules. Secondary nerves are a't a right angle to the midnerve and branch out frequently to form reticulum with each other and with the primaries. In the laminae attached to the axis of penultimate pinna, the nervation is quite similar to that of ordinary pinnules. Fertile specimen not known.
