w. H. PEARSON. 



rotund or ovate, slightly concave, 9 cells long by 9 cells 

 broad, 7 X 10, 7 X 8, emarginate, or entire, sinus shal- 

 low, lobes obtuse; cells moderate to large, oblong-hexa- 

 gonal or subquadrate, leptodermous, lumen echlorophyllose, 

 no trigories. Underleaves broadly-subulate 3 cells high, 

 bottom ro w 3 cells wide middle 2, apex 1, sometimes 

 almost obsolete, merely 1, 2 or 3 raised cells not separate 

 from stem. Inflorescence on short postical branches arising 

 from near the base of the stem, rarely elongated then 

 appearing acrogenous. Bracts closely imbricate, larger than 

 the leaves, ovate or subquadrate, bifid, sinus about Vs*^ or 

 74*^ deep, the 3rd and #ii pairs containing the antheridia, 

 whose leaves have a further lateral segment; antheridia in 

 pairs, roundish-oval, stipitate; pistillidia oblong, 10, formed 

 of 12 tiers of cells. Perianth oblong-oval, trigonous, 

 mouth incurved, subentire, projecting about half above the 

 bracts, lower portion composed of two layers of cells, 50 

 cells round, upper portion of one layer, 70 cells round. 

 Calyptra delicate texture. Capsule oval, brown. Spores light 

 golden brown. Elaters rather darker, bispiral.

Hab. Growing on peaty soil by a river near Umpumulo. 



Obs. The postical branches and trigonous perianth 

 induce me to refer this species to the genus Gephalosia and
