branches, singly or in groups of 2 to 5 from the axils of consecutive 
underleaves, rarely 2 sexual branches borne from the axil of the 
same underleaf, in such a case both being of the same sex; 9 bracts 
2 or 3 pairs, much smaller than the leaves, innermost bracts ovate, 
unequally bifid to the basal row of cells, slightly verruculose, lobes 
subulate, connivent; bracts of second row larger, one-third the size 
of leaves, ovate, with a single marginal tooth, bifid about three- 
fourths, lobes spreading or connivent, sometimes unequal ; bracteoles 
similar to bracts; perigynium undeveloped: ¢ bracts 2 to 4 pairs, 
concave to subcomplicate, ovate, bifid about one-half, lobes incurved, 
subulate, spreading.

rantia Sullivantii (Aust.) Underw., of North America, agrees 
very closely with the Hawaiian species. It differs, however, in the 
following characteristics: the teeth of the leaves are usually longer, 
broader and parallel, and are separated by a deeper sinus; the terminal 
cells of the leaf are smaller, and those of the basal margin are shorter 
and broader, all the leaf-cells having slightly thicker walls.

Dioicous (?): plants yellow-brown, depressed, cxspitose or 
scattered among other bryophytes: stems slender, simple or rarely 
branching, sometimes (very rarely) bearing true flagella, prostrate, 
ending obtusely or attenuated, flagelliform ; flagella short ; rhizoids 
borne in clusters at the base of the underleaves: leaves approxi- 
mate, imbricated at the base, apex free, obliquely inserted, obliquely 
ovate, verruculose, antical base arching partly over stem, postical 
base decurrent, antical margin dilated, apex subtruncate or rounded, 
sometimes slightly retuse: leaf-cells with slightly thickened walls, 
trigones minute: underleaves distant, twice as broad as stem, 
broadly ovate-subrotundate, subcordate at the base, apex retuse ; 
underleaf-cells similar to those of leaves: 9 bracts arranged in 2 rows,
