3. Cephalozia carihbeania Fulford, sp. nov. 



Cephalozia sandvicensis, Wright, Hep. Cub. Wright., in Hb. Non C. sandvicensis (Montagne). 



Caules parvi, subtiles, subvirides brunnei-suffusi, 1-3 cm longi, ramis ventrali- 

 intercalaribus, foliis sublongitudinaliter insertis. Folia patentia, ovato-truncata, 

 bifida, segmentis rectis vel curvatis, apicibus 2 vel 3 cellulis; apicis cellulae 65- 

 104 X 15-26 /x\ laminae cellulae 65-78 X 65-78 n, pariete uniformiter incrassata. 

 Amphigastria obsoleta. Inflorescentia masculina ventralis, bracteis similibus foliis; 

 inflorescentia femina ventralis, bracteis bifidis acutis. Perianthii os longe ciliatum, 

 cellulis 150 X 26 p. 



Plants small, slender, pale green tinged with brown, in depressed mats or among 

 other bryophytes; stems 1-3 cm long, with leaves 0.5-1.0 mm wide, irregularly 

 branched, the branches ventral-intercalary, leafy, or short and often bearing a male 

 or female inflorescence. Rhizoids frequent, from the ventral side of the stem, often 

 branched at the tips. Line of leaf insertion nearly longitudinal. Leaves distant to 

 approximate, plane, widely spreading to slightly ascendant, ovate 0.5-0.65 mm long, 

 0.25-0.45 mm wide, the dorsal margin convex, bifid to one-third their length, the 

 segments usually straight, long triangular, acuminate from a 2-celled base, ending 

 in a tip of 2 long cells, each 4-6 or more times as long as wide; cells of the segment 

 tip mostly 65-104 X 15-26 //., of the sinus margin 65-85 X 65-68 //., a few smaller, 

 the walls uniformly thickened, without trigones, the cuticle smooth. Underleaves 

 absent. Plants dioicous. Male inflorescence terminal becoming intercalary on the 

 stem or on a short branch, the bracts in many series, resembling the leaves, densely 

 imbricate, concave. Female inflorescence on a short ventral branch, the bracts and 

 bracteoles in 3 or 4 series, bifid, the segments entire, those of the innermost series 

 long-acuminate, the tip cell very long. Perianth cylindrical below, with 3 broad 

 rounded keels above, the mouth long-ciliate, the cilia mostly 5 cells long, the cells 

 often 150 X 26 /t*.
