in others (fruit mature) partly obliterated or only at the apex to 

 be seen, mouth constricted denticulate, setulose, ciliate or laciniate ; 

 walls leptodermous, except at the very base, where it changes into 

 the stem or branch, or in a few species, the lower half 2-3 cells 

 thick. Andro3cia spicate or amentiform, in different places, but 

 very rarely hypogenous, $ bracts immediately below the female 

 flowers.

Dioicous, usually cladocarpous, densely but thinly caespitose, 

 flagelliferous, small, brown in colour. Stems prostrate, sub- 

 pinnate, cells of the stems about 6 in diameter, cortical 14, inner 

 slightly larger and more pellucid ; branches radiculose ; rootlets 

 whitish. Leaves small, subimbricate, slightly concave, when dry 

 much incurved, catenulate, oval-rotund, slightly decurrent, bifid 

 to about the middle, sinus more or less obtuse, segments patulous 

 or subconnivent, acute, 5 rows of cells, 1, 2, 3, 4, 5 wide; cells 

 small to smallish, subquadrate or rhomboid, leptodermous, chloro- 

 phyllose and subopaque, walls firm, no trigones. Stipules 

 wanting. Branches % postical, short, rarely subelongate. Bracts 

 twice as large as the leaves, oblong, bifid to about the middle, 

 segments subulate-acuminate, margin denticulate or spinulose ; 

 bracteole similar, or entire and broadly subulate, free, margin 

 denticulate or spinulose. Perianth deeply emersed, linear- 

 fusiform, 4 times longer than broad, composed of one layer of 

 cells, the whole length deeply tri-carinate, mouth constricted, 

 setose or ciliolate. Calyptra delicate. Capsule reddish-brown, 

 oval-cylindrical. AndrcBcia terminal on postical branches, jula- 

 ceous ; perigonial bracts somewhat similar to the leaves and of 

 the same size, few pairs; perigonial bracteoles ovate-lanceolate, 

 entire or with a slight notch on one side near the middle ; anther- 

 idia oval.
