The fronds of young plants are simple, a gradual change to the pinnate form 

 occurring long before maturity. So far as "Qymnogramme t [Syngramme t) sub- 

 trifoliata Hooker" in Sp. Fil.. 5: 152, J'late 298, ever was described, it is indis- 

 tinguishable from this Stenocklaena. The most similar species is Lomariop&ia 

 spectabilis Mett.. of which the fertile pinna are described as narrowly linear.

The fronds of tbis plant, both the sterile and the fertile, have altogether the 

 aspect of those of Stenochlacrta, and the absence of tubercles on the bases of 

 the stipes helps to conceal its real affinity. However, the oblique annulns and 

 the insertion of the sporangia establish its place beyond doubt.
