Differs from D. antarcticum in its more rigid obscure leaves, 
with a wider nerve, and copious alary cells occupying the whole 
width of the base, and not confined, as in that species, to the

iterumque ramosis fastigiatis. Folia erecto-patentia, striata, inferne ovato- 
lanceolata, subulata, anguste attenuata, nervo ultra medium a pagina in- 
distincto levi, integerrima, complicata, cellulis elongatis angustis, alari- 
bus pluribus subconcoloribus quadratis ; perichzetialia convoluta, late ova-

ferne elliptico-lanceolata, subulata, integerrima, nervo angusto superne 
excurrente, marginibus incurvis, cellulis basi angustis superne oblongis,

angusteque subulato-attenuata, marginibus incurvis integerrimis, nervo 
lato superne a lama indistincto, cellulis elongatis oblongisque, alaribus 
pluribus planis hyalinis fuseisque; perichetialia in eylindrum brevem
