HooKEKiA ANOMALA, Muell. ( fi// ocoi)/u7um, Schwaegr. ; Pterygophyl- 

 lum. Mitt. ), a species with erect tomentose stems and sparse leaves, broadly 

 obtuse from a shortly spatulate base, oblique, unequal, coarsely and dis- 

 tantly serrate, the cells thick, large, round-hexagonal, obtuse near the 

 border, and separated by intercellular ducts, is, according to Mitten (Journ. 

 Linn. Soc. xii. 397), a Fuegian species, though stated by Schwaegrichen, 

 probably through mistake, to have been collected originally in Northwest- 

 ern America by Menzies. 



113. PTERYGOPHYLLUM, Brid. (PI. 5, as IlooJceria.) 

 Plants pale green, glossy, piano-foliate ; branches few, rooting 

 at base like the primary stems and similar to them. Leaves 

 large, densely and obliquely imbricate, smooth, chlorophyllose, 

 broadly ovate, obtuse or acuminate, ecostate, entire ; cells of 

 the areolation large, round in the upper part, hexagonal at base. 

 Flowers monoecious ; perichretium small, on a short thick root- 

 ing perichaetial branchlet, serving as vaginule ; perichfetial 

 leaves few, lanceolate, thin. Calyptra mitrate. Peristome that 

 of Hookeria.
