borne en the lobes of the carpocephalum, and not alter- 

 nating with them. 



Very widely distributed, but not common. Cosmo- 

 23olitan. 



LUNULAEIA AdANS. 



Robust, flat, fleshy, bright green, dorsal surface areo- 

 late, each with a simple pore, surrounded by concentric 

 rings of cells. Ventral surface green, with two rows of very 

 lender, colourless, broadly lunate scales, each with a 

 rotund appendage. Antheridia on flat, sessile, dorsal 

 plates. Carpocephalum colourless, or pale green, tender, 

 and scon wilting. Stalk without a groove, hairy, mostly 

 2-4 cm. long ; head of four cruciate, horizontal, tubular 

 involucres, each about 2 mm. long ; perianth absent. 

 Gemmae always present in lunate cups. 



LunuJaria cruriata (Z.), Bum. — Very common in 

 greenhouses and gardens. Introduced. 



FlMBRIARiA, NeES. 



Fronds tough, flat or concave, linear rarely forked, 

 with a thick midrib. Dorsal surface areolate, with small 

 air chambers ; pores conspicuous, simple, surrounded with 

 concentric rings of cells. Ventral surface convex, w^ith two 

 rows of large purple scales, each with an appendage. An- 

 theridia immersed in the frond. Carpocephalum per- 

 sistent, purple, conic or hemispheric, on a long, slender 

 stalk, four lobecl, each containing a single capsule; in- 

 volucre slender; perianth ovate, white, split into^ many 

 linear sections. Capsule globose, with a very short stalk. 

 The small size and conspicuous white fimbriated perianth 

 makes the genus easily recognised. 



Carpocephalum hemispheric, coarselv 

 warted. Spores 150 ^. diar- 

 meter drummondi 



Carpocephalum hemispheric, nearly 



smooth. Spores 60 ^. diameter tenera 



Carpocephalum conic conocephala 



Fiwhriaria dm mwondi, Tayl. — Fronds flat, about 

 1 cm. long, 3-4 mm. wide, dull green, pui-ple beneath and 

 on the margin, midrib thick, but not much produced on 

 the ventral surface, wings broad, thin, margin acute, irre- 

 gularly crenote, new shoots ventral from the midrib, pores 

 large and prominent, ventral scales obliquelv ovate, pur- 

 ple; appendage colourless, not constricted at the base, 

 ligulate. with a shortly acuminate apex. Peduncle to 

 2 cm. ; carpocephala hemispheric, coarsely warted, lobes
