lEICHOMANINE^. Oir. 



sessile apore-cases, mixed with articulated, often olavate hairs. 

 Involucres free, sub-coriaeeoua, forming vertical marginal urn- 

 shaped cysts, truncate at the mouth. Veins forked or pinnate, 

 from a central costa 5 vermles free, the upper anterior one sorife- 

 rous. 



Fronds suh-ooriaceous, decompound. Ehizome creeping.— The 

 thickish texture of the fronds of this fern, and the mode of cutting, 

 produce a general resemblance to DavalUa. The extrorse-mar- 

 ginal cups, and free filiform receptacles, clothed even beyond 

 the involucres vrith sessile oblique-ringed spore-cases, forbid, 

 however, its association with that genus, and leave no alterna- 

 tive but to place it near Trichomanes, with which, in reality, the 

 texture alone disagrees. We cannot indeed, place either Loxsoma 

 or the Trichomanes group among the Poh/podinece.

Sori involucrate, seated in extrorse-marginal (rarely recurved) 

 cysts, sunk in or free on the margins of the fronds ; the veins 

 continued into filiform exserted, sometimes capitate receptacles, 

 which are free within the cysts, and bear sessile lenticular 

 spore-cases at their base. Irmolucres funnel-pitoher-shaped or 

 shortly bell-shaped, truncate and entire at the mouth, or two 

 lipped. Veins simple forked or pinnate, from a central costa, 

 or simple costa-like in the ultimate segments, or flabeUato- 

 dichotomous ; venmles free, sometimes excurrent in the marginal 

 teeth. 



Fronds simple pinnate or decompound, pellucid membranace- 

 ous, rarely coriaceous, Bhizome creeping (sometimes filiform) 

 or csBspitose. — A beautiful and extensive genus of delicate semi-
