PATAGONIA— TIERRA DEL FUEGO: Corral. Thaxter 157 p.p. (MICH); Puerto 

 Varis, Fulford 507 p.p., 640 p.p. (Hb Fulford) : Chiloe I., Capt. King (NY) ; Magellan Straits,

 collector (NY) ; Hoste I., Harding Peninsula, Orange Bay [Chilean ship "Yelcho"] Chelminski 

 4 p.p., 11 p.p., 12 p.p. (Hb Fulford). 



FALKLAND ISLANDS: Pto Stanley, Skottsberg 198 1 19071 (G). 



Additional collections have been reported from Patagonia — Tierra del Fuego (Arnell, 1957; 

 Herzog, 1942a; Herzog & Schwabe. 1939; Massalongo, 1885). 



The species was first collected on Auchland Islands by Hooker (NY) and appears to be 

 fairly common in New Zealand and Australia as well as in the southern tip of South America. 

 It is another of those species with an Antarctic distribution.

Plants of small to medium size, whitish to greenish-yellow, filamentous, to 

 compact and bristly, in mats or erect tufts; leafy stems 4-6 cm long, with 

 leaves to 0.8 mm broad, fleshy, turgid, regularly bipinnate to sometimes tripinnate, 

 often fan-shaped from an almost leafless base, the tips often recurved; lateral 

 branches long with shorter secondary branches, a few becoming flagelliform, the 

 dorsal half-leaf bifid or quadrifid, ventral branches occasional, long, leafy, rarely 

 becoming flagelliform, or coarse with distant leaves below and becoming densely 

 leafy above and readily detached from the stem, or short, female; stem in 

 transverse section brownish-yellow, the unistratose cortex of 18 or 15 large cells 

 surrounding the medulla of many smaller cells. Line of leaf insertion transverse. 

 Rhizoids from cells of the bases of the underleaves. Stem leaves distant to 

 subimbricate, subrectangular in outline, averaging 0.86-0.5 mm, erect spreading, 

 5- or 6-parted to near the middle, the lamina mostly four rows of cells high.
