The small abnormal barren form is the only one yet recorded from Viti. In it the frond is small, 
nearly sessile, lanceolate, acute above, and with smaller and more distant pinne below; the pinne are 
small, oblong, and with a short petiole. The drawing and description of the plant given by Brackenridge 
agree entirely with this abnormal form. It has not been detected by any one else out of New Zealand, so 
that it seems to me probable that some error has crept into the labelling of this plant.
