Gen. Cuar. Frond compressed, distichously pectinate, or subterete, and 
quadrifariously aculeate, formed of three strata surrounding a central 
articulate filament or tube ; medud/ary stratum of longitudinal, densely 
interwoven filaments ; izdermediate of larger, roundish cells; cortical 
of minute, coloured, vertically-seriated cellules. Fruits of both kinds 
external, pedicellate or sessile. Cystocarps (imperfectly known). Re- 
ceptacles of tetraspores ovoid or globose, containing within nume- 
rous cavities parietal zonate ¢efraspores mixed with simple parane- 
mata.—PuaceLocareus (Lndi.), from dakedos, a tuft or fascis, and 
kaptros, fruit: the fruit is club-shaped in the typical species. 
Frons compressa, distiche pectinata, aut teretiuscula et quoquoversum aculeata, 
triplici strato tubum articulatum centralem ambiente contexta; strato me- 
dullari filis longitudinalibus densissime intertextis, intermedio cellulis majo- 
ribus rotundatis, corticalt cellulis minutis coloratis verticaliter seriatis. 
Fructus utriusque generis externi, pedicellati v. sessiles. Cystocarpia (viz 
nota). Receptacula tetrasporarum ovoidea v. globosa, in cryptis numerosis 
infra peripheriam exsculptis tetrasporas zonatim divisas parietales inter para- 
nemata nidulantes foventia. 
PuaceLocarrus complanatus ; frond narrow, plano-compressed, with an 
immersed and obsolete midrib, decompound; branches and ramuli 
pectinato-pinnatifid, the laciniz subulate and distichous ; nemathecia 
minute, globose, sessile beneath the tips of the laciniz. 
P. complanatus ; fronde angusta plano-compressa immerse v. obsolete costata 
decomposita, ramis ramulisque pectinatim pinnatisectis, lacinulis subulatis 
distichis, nematheciis minutis globosis infra apices lacinularum sessilibus.
