more cells, and the cells of the basal part are longer. Male and female in- 

 florescences and sporophyte were not seen. PI. 52. Fig. l,k. 

 Habitat: On earth and tree roots. 



JUAN FERNANDEZ ISLANDS: Masafuera, Quebrada del Mono, 370 m, Skotlsberg 

 142 p.p. (type, Hb Herzog). It has also been reported from Tristan da Cunha by S. Arnell 

 (1958).

1963. 



Lepidozia pseudozoojisis Herzog in Skott.sberg, Nat. Hist. Juan Fernandez Easter Is. 

 2 5 : 723. f.5. 1942. 



Plants very small, whitish green to yellowish, in small patches; stems very 

 slender, to 1 cm long, with leaves to 0.15 mm broad, pinnate, the lateral branches 

 distant, the half-leaf subulate, the ventral intercalary branches occasional; 

 stem in transverse section of a cortical layer of six or eight large cells surrounding 

 the numerous small cells of the medulla. Rhizoids from small cells of the bases 

 of the underleaves. Line of leaf insertion transverse. Stem leaves distant, 

 more or less ascending, incurved or spreading, quadrate in outline, mostly 0.35 mm 

 long, trifid to within one cell of the base, the lamina one cell high, six cells across 

 (two for each segment) ; segments to six cells long, cells near the base mostly 

 70 fi long, those near the tip shorter. Stem underleaves much smaller than the 

 leaves, bifid or trifid, the segments one or two cells long. Branch leaves with one 

 segment less. Male and female inflorescences similar to those of T. sejuncta. 

 PI. 52. Fig. 2, a-c. 



Habitat: On wood, fern fronds, or over mosses. 



JUAN FERNANDEZ: Centinella-Rueken, 530 m, Skottsberg 227, (type Hb Herzog). 

 It has also been reported from Southern Patagonia (Herzog. 1954) and Juan Fernandez 

 (Arnell, 1957). 



This species appears to be closely related to T. sejuncta but it is of about 

 one-third the size of that species and the cells are shorter.
