 PHYLLOPHOKA PALMETTOIDES.— J". Ag. 



Gen. Char.— Frond flat, rigid, nerveless, uniformly cellular ; cells minute, roundish 

 angular. Fructification: "1. Tubercles (favellidia), scattered over the surface 

 of the frond, and containing a mass of minute roundish or angular spores ; 



2, Warts (nemathecia), seated on the frond, and composed of radiating monili- 

 form filaments, whose lower articulations are at length converted into spores ; 



3. Tetraspores, on distinct plants, collected into sori, either towards the apex 

 of the frond, or in proper leaflets." — Harvey. Name from <pv\Kov, "a leaf," 

 and (popeo), "to bear." 



Phyllophora Palmettoides. — Stem cylindrical, filiform, short, simple 

 or sparingly branched, gradually expanding into an obcuneate or obcor- 

 date flat frond, simple or only once forked, frequently proliferous from 

 the apex ; tetraspores collected into a roundish or transversely ovate 

 sorus in the middle of the frond.

Description. — Root, " a widely spreading disc, an inch or more in 

 diameter." Fronds densely tufted or scattered, two to three inches in 

 length. Stem a quarter to one inch in length and one-fifth of a line in 

 thickness, gradually expanding into a flat oblong, obcuneate or obcordate 

 frond, once or rarely twice divided, often entire or simply emarginate ; 

 the axils rather acute, the apices rounded. Structure somewhat loosely 

 cellular ; central cells larger than in the other species, those at the 

 surface veiy small. Substance rather rigid, membranaceous, not 

 adhering to paper in diying. Colour, a bright rosy red, brighter than 

 in the preceding species, not changing in drying. Tetrasj)ores collected 

 into roundish or transversely oval sori in the middle of the frond.
