 A. Cunningham. Hooker. 



Symeiwpliijllum — Membrane-leaved.

A BEAUTIFULLY crisped and undulated Fern from New Zealand, 

 allied to Hytnenophyllum crispatum, but having larger and more 

 divided fronds. A Selaginella-looking species. 



Fronds erect, stiff, almost deltoid, tri-quadripinnatifid, broadly- 

 ovate, witli narrow, linear, entire, undulated segments. 



Stipes and rachis winged. 



Length, of frond ten or twelve inches. 



Involucres broader than the segments, terminal, free, orbicular, 

 entire, and two-valved to the base. 



Rhizoma like Hymenophyllum crispatum, but still shorter. 



Requires a very humid atmosphere, with a temperature of 

 from 40° to 65°. 



The plant was kindly communicated by Mr. Backhouse, of 

 York.
