Obs. — This is a pretty little species, and thougli it may possibly 

 be only a form of Jinir/. aljjestr}>< Sehleich., yet its liabit, small, 

 secuud, acutely bifid leaves witli acute segments and different 

 cell structure lead me to look upon it as distinct.

Dioicous, caespitose, small to medium in size, of a pleasant, 

 bright, light green colour. Stems prostrate or suberect, ver}^ thick 

 for the size of plant, frontally compressed, 9 and 10 cells by 14, 

 of a brown colour beneath, the postical cortical layer of cells lig- 

 neous and indistinctly cellular, the antical cortical cells smaller 

 and delicate, inner hexagonal, thin walls, with numerous dark 

 granules in each cell ; radiculose, rootlets very copious, on all the 

 under side of stem, whitish, thick, long ; simple or furcately 

 branched, branches often arising from base of perianth. Leaves 

 succubous, horizontalh^ inserted, ascending, imbricating or accres- 

 cent, closer and larger near the apex, subcomplicate, obovate, 

 deltoid, broadly ovate, bifid or irregularly trifid to about the 

 middle, margin entire or irregularly dentate or erose, segments 

 acute or somewhat obtuse, often dentate about the middle, sinus 

 rounded or acute ; texture somewhat coarse, epidermis smooth ; 

 cells rather large, 4-, 5-, and G-sided, lumen filled with chlorophyl 

 granules giving the plant a character distinct from its allies, walls 

 moderately firm, trigones small. No stipules. Bracts larger 

 than the leaves, l)ifid with large lateral segments, segments irre- 

 gularly and coarsely dentate. Bracteole none. Perianth project-
