W. H. PEARSON. 



[No. 14. 



.04 X .03, .035, .04 X .025, trigones .01 mm., underleaves 1.65 

 X .6 mm. at the base, segments 1.5 mm. X .3 mm. at the base. 



Hab. In montibus Ankaratra, 1879, (102 K.). 



Obs. A very distinct species, and allied to none with which 

 I am acquainted. 



17. Lophocolea Madagascarienses G. 



Hab. In montibus Ankaratra, 1877, (117 K.) 



Obs. Monoicous, o* amentula on short branches, leaves 

 entire or bifid, underleaves connate with the two collateral leaves, 

 quadridentate. perianth triquetrous, angles slightly winged, ala 

 laciniate. mouth laciniate. 



18. Lophocolea muricata (L. å L.) var. major Pears. 

 Monoicous, cespitose or creeping amongst mosses, of a pale 



yellow colour. Stems about an inch long, cortical layer com- 

 P' sed of narrow cells; sparingly branched, flexuose, radiculose, 

 rootlets fasciculate,few, proceedingfrom the base of the underleaves. 

 Leaves imbricate, alternate, concave, margin recurved, longly 

 decurrent, ovate subquadrate, bifid rarely entire. margin laciniate- 

 ciliate. cilia 5 cells long, antical face densely pilose, pilæ 2 

 cells long. postical face sparingly pilose. Underleaves free, 

 large, bipartite, segments recurved, ciliate, cilia 3 cells long. 

 Bra ets with larger cells, fewer 2—4 celled cilia on the postical 

 face. Perianth terminal on short branches. delicate, with few 

 2, 3-celled cilia on the epidermis, mouth wide, laciniate-ciliate 

 cilia 3—5 cells long. Andræcia on short amentula arising im- 

 mediately from below the perianth, abouth 12 pairs of bracts, 

 small, closely imbricate, terminal, or on the middle of the branch, 

 antical face of bracts slightly pilose. 



Dr Kiær is inclined to think this a distinct species, but as 

 it agrees with Loph. muricata in inflorescence and as the latter 

 species varies extremely in its muricate character, I think this 

 is only one of the forms of it, of which Lophocolea liorridula La. 

 Cost. is another. the Madagascar species agrees very well with 

 the latter species, only the underleaves are described and figured
