CALLOPHYLLIS CORONATA, Haw. 



Gen. Char. Frond carnoso-membranaceous, flat, dicliotomous, formed of 

 two strata of cells ; the medidlary stratum of large, roundish cells, 

 separated by a network of anastomosing cellules; the cortical of 

 vertical, moniliform filaments. Fructification: 1, half-immersed or 

 superficial, frequently marginal conceptacles, containing within a 

 thick, closed pericarp, a compound nucleus, consisting of several 

 nucleoli or masses of spores; 2, cruciate tetraspores, dispersed 

 through the cortical layer. — Callophyllis {Kiitz.), from Ka\o<i, 

 beautiful, and <^vWov, a leaf.

Callophyllis coronafa ; frond thickish, irregularly dichotomous, with nar- 

 row axils ; segments linear-cuneate, very long, repeatedly forked, the 

 apices narrow, not fastigiate; conceptaclcs very numerous, marginal 

 and discal, prominent, crowned with 3-4 blunt, short horns.

Geogr. Distr. As above. 



Descr. Root a flat, fleshy disc. Fronds one or several from the same base, two 

 feet or more in length, very much divided, none of the laciniaj more tluui 

 an inch wide, and the majority of less breadth. The branching is irregularly 

 dichotomous, the principal segments frequently emitting marginal, forked 

 or in-egularly digitate secondary segments. All the divisions and sub- 

 divisions are cuneate at base, but nearly linear for the greater part of their 

 length ; the apical lobes are narrow, not remarkably obtuse, and sometimes 

 subacute, irregular in length, and never fastigiate. The cyslocarps are ex- 

 tremely abundant, closely set along the margin, and also sprinkled over 

 the surface of the principal segments ; they are truncate cones, nearly half a 

 line in height, with a depression or umbilicus at top, surrounded by usually
