 KALLYMENIA EENIFORMIS.— J^. Ar/. 



Gen. Char. — Frond flat, membranaceous, without veins or midrib, consisting of three 

 strata, the inner composed of continuous interlacing filaments, succeeded by a 

 stratum of rather large coloured cells, which are covered by a thin stratum of 

 radiating mouiliform cellules at the surface. Fructification of two kinds, on 

 distinct plants : 1. Favellidia, slightly convex, containing groups of minute 

 spores ; 2. Tripartite tetraspores, scattered under the surface. Name from Ka\hs, 

 "beautiful," and v/xt]i', "a membrane."

Hab. — In shady rock-pools at extreme low-water mark. Not uncommon. Oftener 

 washed on shore from deep water. Spring, summer and autumn. Perennial. 



Geogr. Dist.— Shores of the British Islands; Atlantic shores of France; Mediter- 

 ranean Sea {Ag.). 



Description.— Root, a small flat disc. Stem very short, scarcely 

 cylindrical, about a quarter of an inch long, suddenly expanding into a 

 roundish, reniform, simple or slightly divided frond ; when old, frequently 

 proliferous at the margin with smaller fronds similar to the primary- 

 one. The primary frond varies very much in size as well as in shape, 

 and IS from an inch to a foot or upwards in diameter, the margin 

 generally more or less waved or crisped. Structure composed of a 

 central stratum of slender, articulated, interlacing and anastomosing 

 filaments, occupying nearly one-half the thickness of the frond, the 

 remainder being composed of cells, the inner of which are rather lai-ge.
