Plant description


Lithophytic ferns with semi-erect fronds. Rhizome erect, scaly. Stipe and rachis pale chestnut-brown at base, green above; very densely covered in pale brown hairs. Leaves 1-2 pinnate, narrowly elliptic, to 15 cm long and 45 mm wide; brownish green, densely covered in pale brown hairs. Primary pinnae in 3-10 pairs, flabellate to ovate or broadly ovate; bases unequally cuneate, shortly stalked; margins dentate to entire; apices obtuse to rounded; longest pinnae near middle, to 23 mm long, and 22 mm wide, divided into secondary pinnae up to 10 mm long and 9 mm wide in largest specimens. Sori to 5 mm long. Perispores non-perforate with fimbriate broad ridges. Fruits are golden brown sori along the edge on the underside of the fronds. Seeds are very fine golden brown spores.

Seed collection and propagation

Collect fronds containing sori. Shake fronds to dislodge the spores onto a clean piece of paper. Store spores in liquid nitrogen.
