Notes
In addition to the type are Buwalda 4984 and 5169, both from Kobroör I., the former much like the type. Number 5169 (from forest in steep rocky limestone country) is sterile, with longer fronds than the type and pinnae to 24 x 2.7 cm, with 13-14 pairs of veins but only 22 pairs anastomosing, 2 or 3 pairs passing to a long sinus-membrane.
