uniformly yellow-brown, with a cortical layer of 12 large cells, surrounding the 

 medulla of many smaller cells with thicker walls and large trigones. Line of 

 leaf insertion oblique, nearly longitudinal, the leaves incubous. Leaves distant 

 to subimbricate, cuneate, quadrifid to the middle; segments two, three or even 

 four cells wide at the base, five to seven cells long, ending in a uniseriate tip of 

 two or three cells; lamina five or six rows of cells high, twelve to sixteen cells 

 wide below the segments, eight cells wide at the base, attached to four longi- 

 tudinal rows of stem cells; leaf-cells rectangular in outline at the base of a 

 segment averaging 36 X 18 n, the walls uniformly thin, the cuticle smooth to 

 faintly verruculose. Underleaves smaller, cuneate, quadrifid to one-half of their 

 length, the segments usually uniseriate from a 2- to 3-celled base. Male and 

 female inflorescences and sporophytes not seen. PI. 46. Fig. 1, a-c. 



The species is known from Campbell Island, Tasmania, New Zealand and Australia. 

 The Latin American reports include West Patagonia (Stephani, 1900a) and Magellan Straits 

 and Tierra del Fuego (Massalongo, 1885) : I have seen no plants from these areas.

Plants small, in light green to whitish tufts or mats, or among other bryo- 

 phytes; stems 3-5 cm long, with leaves to 0.8 mm broad, abundantly bi-tri- 

 pinnately branched, the lateral branches to 1 cm long, much branched, 3 mm 

 apart, rarely becoming flagelliform above, the ventral branches long, flagelliform. 

 Stem in transverse section of twelve large cortical cells surrounding the medulla 

 of many smaller cells. Line of leaf insertion oblique, nearly longitudinal, the 

 leaves incubous. Leaves approximate to imbricate, patent, rectangular with 

 the dorsal margin slightly longer, quadrifid to one-third of their length; segments 

 lanceolate from a 2- or rarely 3-celled base, five or six cells long; leaf cells below 

 the segments averaging 50x40 the walls uniformly thickened, the cuticle 

 faintly verruculose. Underleaves similar, slightly smaller, quadrifid to one-third 

 of their length, the segments two or three cells broad below and ending in a 

 uniseriate tip of two cells. Male inflorescence catkin-like, the concave bracts and 

 plane bracteoles in three or four series, the inner series broadly ovate, the apex 

 of three, rarely four, short segments, the margins with occasional teeth. Perianth 

 to 6 mm long, with three broad keels below, four or five layers of cells below, 

 1-layered above, the mouth contracted, crenulate. PI. 46. Fig. 2, a-h.
