Fronde valide eorticato-costata, prolificationibus a coste latere al- 
terutro juxta laminam prorumpentibus subsingulis aut pluribus 
adproximatis vage et dense ramosa, foliolis ovalibus oblongisve 
parce undulatis, venis mieroscopicis a costa excurrentibus densis, 
interjacentibus cellulis angulatis; (soris elongatis, utroque latere 
coste subsingulis?). 
Hab. ad oras Novi: Zelandie  (BERGGREN); eadem ad insulas 
« Auckland » (MoxTAGNE) et ad terram « Kerguelen »? (D' URviLLE). 
— Frons minuta, 4-7,5 cm. longa, dense ramosa et czspites plus 
minus densos globosos efficiens, phyllis singulis vix 9 mm. latis 
et 12-15 millim. longitudine superantibus. Stipites et ramorum 
inferiorum bases denudati filiformes, superiore parte valide costa- 
ta, costà in alam membranaceam excurrente. Rami omnes prolifi- 
cationibus, utroque latere costz:» juxta laminam prorumpentibus, 
singulis aut sepe pluribus adproximatis, formantur; nunc quoque 
extra costam, a venis laminam percurrentibus phylla prolificantia 
pauciora sparsim emergunt. Phylla prolificantia sunt jam juvenilia 
stipite brevi affixa, et costà stipitem continuante valide costata, 
lanceolata aut sepius ovalia et sensim oblonga obtusiuscula, mar- 
gine integro parce undulato. A eosta utrinque proveniunt vens: mi- 
croscopicze, cellulis directione venarum prolongatis constitutze, levi- 
ter flex:e et. anastomosibus invicem hic illie junctzs, interjacente 
laminà cellulas angulatas breviores offerente. In phyllis admodum 
juvenilibus, in quibus costa fere vena subsimili formatur, ven: 
laterales suboppositz?e adpareant; costa autem mox corticata et in- 
crassata vens subinordinatze occurrunt.
