of the Tribe Trigonanthee. 5 
Subgenus Eulepidozia Spruce, 1876. 
Plants rather large, czespitose, pinnate, more or less plumose : 
leafy branches nearly always lateral, in a few species rarely postical 
and flagelliform : leaves incubous, quadrifid about one-half : perianth 
fleshy, 2 to 4 cells thick, mouth subentire or denticulate, rarely 
ciliate.

PLATE I. 
Monoicous: depressed-ceespitose, pale green: stems pale green, 
oval in section, about, six by eight cells, cortical cells (in about 16 
longitudinal rows) and internal cells about the same size, with 
uniformly thickened walls: lateral branches attenuate, flagelliform, 
rarely blunt: postical flagella infrequent ; rhizoids frequent, color- 
less, borne in small clusters at the base of the underleaves: leaves 
approximate, obliquely inserted, spreading, plane, quadrifid (trifid, 
rarely bifid) about one-third ; lobes subulate to narrowly triangular, 
acute, parallel, about 4 cells broad at the base and 8 cells long, 
usually ending in a row of 2 cells ; sinuses separating lobes subacute 
or obtuse ; leaves on branches approximate or slightly imbricated, 
similar to stem-leaves but smaller, usually trifid ; leaves on attenuated 
branches minute, usually bifid ; leaves subtending branches oblong, 
quadrate-ovate, bifid, lobes spreading, subulate : stem-underleaves 
about half the size of the leaves, distant, subquadrate, quadrifid 
about one-fourth ; lobes subulate, parallel, 2 to 4 cells long, 1 to 2 
cells broad ; sinuses separating lobes obtuse ; branch-underleaves 
smaller than those of stem, similar, quadrifid : cells in the middle 
of leaf arranged in rows, cavities with rounded corners, walls 
thickened, trigones small ; cells in the middle of underleaf similar to 
those of leaf: 9 inflorescence borne ona short branch; bracts usually 
in three pairs ; innermost bracts broadly orbicular, denticulate at
