Judging from the descriptions this plant seems to be dimorphous 

 i.e. with the barren fronds 3-foliate (with the latéral segments 

 forked) and the fertile fronds 5-foliate (with the lowest segments 

 forked). This is not quite correct, for spécimens gathered in 

 Bornéo by Dr. Nieuwenhuis, determined by Dr. Christ, hâve the

 variety of this species cultivated in the Buitenzorg garde ns lias 

 both barren and fertile fronds as well 3- as 5-foliate. 



Var. oi'iiala: Fronds provided with broad, whitish or

From an examination of Zollinger's No. 2925, this plant is 

 undoubtedly no Asplenium. Baker already referred it to Diplazium 

 (Hk. Bk., Syn. Fil., 490). The scales are finely cancellate, i.e.
