Notes
There is some Variation among the specimens included here. One collected by C. G. Matthew at Padang Panjang has thinner pinnae than the type, with slender hairs on lower surface of costae and costules; it also has the basal pair of pinnae distinctly reduced (12 and 17 cm long) with much-narrowed bases. Other collections show different parts of fronds and are difficult to com- pare.
