p. 74. — Fronde sessili, enervi, crassiuseula, in lobos numerosos 
cuneatos ascendentes divisa, segmentis rotundatis, s:epe margine 
precipue versus basin crispatis, axillis angustis; cystocarpiis in 
intermedia zona frondis semicirculariter expans:e sparsis ; soris mi- 
nutissimis plurimis extra regionem eostalem secus lineas margi- 
nes versus flabellatim dispositas excurrentes dispositis. 
Hab. ad «Golden Gate» Californi:& (A. D. FnvyE). — Frons 
circiter 7-8 em. longa, in segmenta 4-5 principalia profunde fissa, 
segmentis his iterum in lobos 4-5 verticaliter ascendentes divisis. 
Margo frondis versus basin loborum crispatus undulatusve, cete- 
rum planus. Apices loborum rotundati; axillie vero angustissim:e. 
Superficies frondis cellulis amplis tessellata. Cellul:e interiores ma- 
gna, quadrangulares. Color saturate ruber. Substantia crassiuscula. 
6. Costata J. Ag. Sp. III, 3 (1898) p. 75. — Frons junior fere tota conformis 
elongata, sezmentis cuneato-linearibus patentibus plus minus divisa et pro- 
lifieationibus ramosa, adultior infern:; eos'ata et prolitieationibus a costa 
emergentibus ramosa.

Kuetz. Sp. p. 871, Tab. Phye. XVI, t. 26, f. c-d. — Stipite demum sub- 
ramoso, ramis singulis in laminas cuneatas eostatas abeuntibus, 
costis supra stipitis ramos in nervos obsoletiores anastomosantes 
solutis, frondibus cuneato-flabellatis subpalmatim laeciniatis, laci- 
niis cuneato-oblongis a margine sspe proliferis, venis superficia- 
libus sursum longius conspicuis; soris punctiformibus, per partem 
superiorem frondis sparsis. 
Hab. in mari australi ad insulas Malouinas (J. D. HookER). — 
Frons 9-18 cm. longa, angusta v. latiuscula, in stipitem simplicem 
vel ramosum 1-1,5 em. longum et ultra attenuata, forma varia: nunc 
elongata, lacera, junior latior lobata, laciniis latis, obtusis, emar- 
ginatis retusisve. Nervus centralis elongatus basi latus, in fron- 
dibus senioribus ultra medium extensus, in junioribus cito evani- 
dus. Color ruber, demum fuscescens. Substantia crassiuscula. Ha- 
bitu frons juvenilis magis AAodymeniam quam  Nitophyllwm re- 
fert, in seetione transversa monostromatica; frons vero adultior 
eystocarpifera est cellulis superpositis contexta et multo firmior. 
Sori in planta adultiore sunt validi, magis quam in juvenili oblongi, 
secus lineas flabellatim excurrentes evidenter dispositi.
