TRICHOMAXINE^E. CO.. 



sessile spore-cases, mixed with articulated, often clavate hairs. 

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

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

 from a central costa ; venules free, the upper anterior one sorife- 

 rous. 



Fronds sub-coriaceous, decompound. Ehizome creeping. The 

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

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

 ginal cups, and free filiform receptacles, clothed even beyond 

 the involucres with 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 Potypodinece.

Son 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. Involucres funnel-pitcher-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 flabellato- 

 dichotomous ; venules free, sometimes excurrent in the marginal 

 teeth. 



Fronds simple pinnate or decompound, pellucid membranace- 

 ous, rarely coriaceous. Ehkome creeping (sometimes filiform) 

 or caespitose. A beautiful and extensive genus of delicate semi-
