Another curious dwarf Fern, yet not nearly so diminutive 

 as the Niphohohis rupestris; the dark, shining green fronds con- 

 trast greatly in colour with the generality of the Fern tribe. 

 It is a species easily to be procured from Nurserymen, and one 

 well worthy of cultivation, as its dwarf habit enables it to be 



grown underneath the larger Ferns.
