HAYALLIEJE, lOUl. 



ouB femsj distinguished from DavalUa 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. 



§ Mierolepia. — Sori distinctly intramarginal. 

 Ex.: M. calvescens, Fresl. I M. platyphylla, J. Sm. 



M. trichosticha, J". Stn. M. ina3quali8, Presl, 



M. striffosa, Fresl. j M. splendens (Davallia, Sl.J 



M. Speluncae {Polypodium, Idn. j Dicksonia multifida, Sto.J 

 § Saccoloma. — Sori sub-marginal. 

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

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

 or sub-marginal ; the receptacles terminal, Indusiimi 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. 

 Veifis forked or pinnate, from a costa ; 'oenules free. 



Fronds herbaceous or coriaceous, pinnate or pinnately decom- 

 pound. Bhizome creeping. — ^A well-marked genus, though the 

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

 the shorter cup-shaped sori are distinguished from Mierolepia 

 both by their texture and by having their sori marginal. 

 § Stenoloma. — Induaia cup-shaped, marginal. 

 Ex. : D. tenuifolia, 8w. I D. clavata, 8m. 



D. Schlechtendalii, Fresl. D. uncinella, Kze, 



D. aculeata, Sm. \ D. fumarioides, Sw. 



§ ScyphuUvria. — Indusia tubulose.
