clavate and fertile, a few equal and sterile. 

 Leaves of sterile stems smaller, less imbricate, 

 spread inc^, broadly oval or roundish ; bilobate, 

 sinus acute, lobes acute. Flowers terminal, paroi- 

 cous. Bracts two to five, joined, rarely two, twice 

 as large as the leaves, ovate, orbicular, sulv 

 cordate at the base, ventricose, bilobcd. Antheridia 

 twin, rarely solitary, globose. Perianth immersed, 

 apex obscurely 4-5 angled, at length lobed, 

 base concrete with the involucre. Calyptra glo- 

 bose-oval, constricted at the base, with six to 

 eight sterile pistillidia. Capsule four-valved, the 

 valves sometimes bilobed. Elaters bispiral, 

 obtuse. 



It grows, in broad low patches, of a reddish or 

 purplish brown colour on the surface, as if scorched. 

 The parts not exposed to the light paler and more 

 tender. On stones in moist sites, under trees the 

 plants are often greener, only the tips slightly 

 browned, but on exposed sub-alpine rocks the 

 whole plant becomes of a purple black. — {Plate <5,
