nodulose legs. Male plants in separate tufts ; infl. gemmaceous, axillar 

 and terminal, bracts broadly truncate oval, with a narrow vertical 

 lamina, serrate at apex, antheridia numerous, oblongo-cylindraceous, 

 with very few paraphyses. 



Hab. — Wet rocks and moist shaded soil. River side at Castle Hornoch, 

 near Penzance, ^ (Curnow, Nov. 1868) ! ! Mousehole cave, Penzance 

 (Curnow, Dec. 1869) ! ! 



This beautiful moss closely resembles F. polyphyllus, but may be readily 

 distinguished by the apex of the leaf, which is acute with the margin sharply 

 serrate. We have only the male and barren plants, and it truly belongs to 

 the Canarian Flora, the fruiting plant having been brought from Teneriffe by 

 Bory de St. Vincent. The species is also met with in Portugal, Tuscany, 

 and at Monte Pisano, near Genoa, and at the latter station a few capsules 

 have recently been found by Mr. Fitzgerald.

Dioicous ; in erect rather dense lurid-green tufts, intermediate 

 between F. taxifolius and adiantoides. Stems sparingly branched, fasci- 

 culate at base, rigid. Leaves densely crowded, firm, lineal lanceolate, 

 parabolically acute, the nerve reaching apex or vanishing below it ; 

 vag. lam. reaching half length of leaf, inferior lam. lanceolate, narrowed 

 and slightly decurrent at base ; margins very minutely serrulate, in 

 upper part crenato-serrate, all with a pale border of four rows of incras- 

 sate rounded cells, the other cells obscure and smaller than those of 

 F. adiantoides. Setae from middle and lower part of stem, short, pale 

 red, the perichaetial bracts ovate concave, extended into a narrow 

 lamina ; capsule rather small, ovate suberect or inclined, brown, lid 

 rostrate, nearly equal to capsule, peristome deep red, the teeth strong, 

 cleft to middle into two nearly equal rough legs ; spores small. Male 

 plants in distinct tufts, the infl. axillar, bracts short, broadly ovate, 

 apiculate. 



Hab. — Wet rocks near the sea and on the ground in hilly places. Fr. 12 — 3.
