Plants large, rareJy small, pale or yellowish- green, rarely very 

 green, densely osespitose, tufts depressed, rarely erect or pendulous. 

 Stems in many species firm, beautifully feather-like, pinnate or 

 bipinnate; branches lateral, sometimes attenuate and radiculose 

 at the apices, rarely, and principally in small species with postical 

 branches, which are frequently flagelliferous and radiculose. Leaves 

 incubous, small, in some species very minute, sometimes broader 

 than long, very oblique, with antical margin much longer and 

 rotundate, decurvo-concave, palmate or quadrifid almost to the 

 base, rarely 5-6- or only 2-3-fid, segments subulate, entire or 

 furnished at the antical base with a few teeth, in a few species all 

 the margin dentate ; cells usually smallish, quadrato-hexagonal, 

 inferior subelongate, angles slightly thickened, cuticle often rough ; 

 in Micro- Lejndozia very small oblong-quadrate. Stipules similar 

 to the leaves but symmetrical, in Eu-Lepidozia slightly smaller, in 

 Micro-Lepidozia about half the size of the leaves. Inflorescence 

 dioicous, in a few species (chiefly Micro-Lejjidozia) monoicous ; 

 ? on the stem, rarely on the branches, hypogenous. Bracts 3-5 

 pairs, appressed, concave, innermost frequently about three times 

 (in small-leaved species up to eight times) larger than the leaves, 

 at the apex 2-4-fid, margin denticulate or spinose. Pistillidia 

 20 or less, the sterile surrounding the base, or a little higher,
