Morphology
Goniophlebium pseudoconnatum is closely similar to G. subauriculatum, with which it co-occurs. The best distinction is in the rhizome scales, which, in G. pseudoconnatum, are dull brown, nearly entire or more strongly dentate near the acumen than at the base, have relatively short, wide cells in the acumen and a relatively wide apex. In G. subauriculatum the scales are more rufous, with a strongly and irregularly dentate base, they have longer, narrower cells in the acument and a long, filiform apex. The distinctions, however, are not completely sharp and intermediates occur. Other, even less clear-cut characters in which the two differ are:
Incomplete specimens (without rhizome) cannot be identified with any certainty.
