nomitniiin revolutiun, Carr. and Pears. Exs. 

 No. 217, 218. 



Densely caespitose in black tufts. 



Base stolonifcrous, dark brown, brittle, spar- 

 ingly rooting ; shoots ascending, simple, h inch 

 to I inch long, rigid, innovations from the apex, 

 or axils of upper leaves. Leaves bifarious, imbri- 

 cate, complicate-concave, bidentate, erect, roundish 

 or elliptic-obovate from a rather narrowed base ; 

 smaller and more distant near the base of the 

 stem, gradually enlarging upwards. Lobes equal, 

 acute, cuspidate, with a deep sinus, about one-third. 

 Margin narrowly reflexed. Texture dense, polished, 

 pitch-black. 



In size and emargination of the leaves it is 

 intermediate between iV. einarginata and N. Fiiuckiiy 

 but the narrow revolute continuous border will at 

 once distinguish it from these. The leaves of A^. 

 einarginata are usually reliexed at the base, but the 

 lobes are blunter, and plane at the margin. — [Plate
