Gen. Cuar. Frond filiform, pinnately decompound, articulated, but gra- 
dually becoming coated with a layer of small, coloured cellules ; 
branches and ramuli furnished with minute, bristle-shaped, articu- 
lated ramelli. Cystocarps terminating short branches, involucrated or 
naked, containing within a closed, membranous pericarp, numerous 
nucleoli of oblong spores. Zetraspores formed along the ramelli, ex- 
ternal, sessile, triangularly parted—Spyripia (Harv.), from orupes, 
a basket. 
Frons filiformis, pinnatim decomposita, articulata, sensim cellulis minutis colo- 
ratis corticata; ramis ramulisque ramellis articulatis setiformibus minutis 
plus minus instructis. Cystocarpia ramos breves terminantia, ramellis in- 
volucrata, v. nuda, intra pericarpium clausum membranaceum nucleolos plures 
sporarum oblongarum foventia. Tetraspore ad genicula ramellorum evolute, 
externa, sessiles, triangule divise. 
Spyripia prolifera; frond robust, tall, rigid, terete, inarticulate, very 
thickly corticated, sparingly and irregularly branched ; branches 
simple or forked, more or less beset with short, capillary, tufted, 
branched or simple, ramelliferous ramuli; ramelli setaceous, -jianiolre. 
acute ; tetraspores secund on the ramelli.

bus fasciculatis ramosis v. simpliciusculis ramelliferis plus minus obsessis,

Descr. foot and base of the frond unknown. Frond at least 8-10 inches long, 
probably much more, half a line to nearly a line in diameter, opaque, very 
thickly corticated with minute cellules, sparingly and irregularly branched. 
Branches virgate, 2-4 inches long, simple or forked, alternate or secund, 
spreading every way, either naked or irregularly beset with short branchlets. 
Branchlets springing horizontally from the stem and branches, in tufts or 
single, 3-5 lines in length, capillary, imperfectly articulate or subinarticu- 
late, branched or subsimple, densely clothed with minute ramelli. Ramelli 
a line long, alternate, pateut, subulate, acute, simple at the apex, articu-
