DAYAL1IE2E. Xciii. 



ous ferns, distinguished from Davallia proper, by the short half- 

 cup-shaped fructifications, and intramarginal sori. Saccoloma 

 does not appear to us to present any material difference of struc- 

 ture; we have consequently placed it in Microlepia, retaining 

 for the united group the more expressive name used by Presl. 



Microlepia. Sori distinctly intrama_ 



Ex. : M. calvescens, Presl. I M. platypl; 



M. trichosticha, J. Sm. M. insequa , 



M. strigosa, Presl. \ M. splendens (Davallia, SIJ 



M. Speluncse (Polypodium, Lin. ; Dicksonia multiflda, SwJ 

 Saccoloma. Sori sub-marginal. 



Ex. : M. elegans, Mett. \ M. Hookeriana, Presl. 



M. pinnata, J. Sm. \

Sori indusiate, roundish-oblong or elongate-oblong, marginal 

 or sub-marginal ; the receptacles terminal, Indusium membra- 

 naceous, cup-shaped or tubulose, affixed at the sides and base, 

 thus forming a vertical oblong semicylindrical tubulose cyst, or 

 cup, which is truncate and open at top, i.e., towards the margin. 

 Veins forked or pinnate, from a costa ; venules free. 



Fronds herbaceous or coriaceous, pinnate or pinnately decom- 

 pound. Ehizome creeping. A well-marked genus, though the 

 species differ in the length of the indusium or cup ; those with 

 the shorter cup-shaped sori are distinguished from Microlepia 

 both by their texture and by having their sori marginal. 

 Stenoloma. Indusia cup-shaped, marginal.
