tion of the ii ik si ta observed in Jamaica, that 1 cannot 

 doubt their identity. Ours grows exclusively in the ca\i- 

 ties formed by Shistose rocks along the banks of rivulets, 

 v. c. Little Yadkin ; but there to an immense extent, 

 covering their sides for many yards. The general breadth 

 of the frons is half an inch — the length of a single one two 

 or three inches. Its texture is extremely brittle — the co- 

 lor a pure dark green. A very strong middle rib runs on 

 the under surface, which alone puts forth loots. The 

 frons is generally elegantly dichotomous, and lobed, the 

 lobes rounded, undulate, and often crenate. The female 

 receptacle is on a short peduncle, and extremely hirsute 

 below, rather subcorneal, and appears entire. I found it 

 not yet perfectly in fructification beginning of November.

This is the most common here, though very rarely found 

 in fructification. It creeps about the banks of springs and 

 walls, and on moist stones ; and the frons is generally not 

 so complicated as that of polymorpha, nor so brownish.

I apprehend that the cruciata of Muhl. is this species. 

 The frons very much resembles that of cruciata. The 

 fructification is very beautiful. The peduncle of the fe- 

 male about four lines high, the receptacle nearly globular, 

 four or five cleft below, with numerous hairs or filaments 

 from the divisions. The resemblance to hemisphaerica 

 is not very striking. The frons is small, less lobed than 

 in cruciata, but more rounded and broader than in the 

 next. The lower surface and margin purple. On flat 

 rocks. Fr. in summer.
