aiul acutely cloven than the rest ; on procumbent 

 stems seldom secund, but merely incurved or even 

 spreading. Stij)ules minute, seldom broader than 

 the stem, variable, usually lanceolate-a\vl-shai)ed, 

 with one or more lateral teeth, sometimes entire, 

 rarely bifid, never twisted. Inflorescence dioicous. 

 Male plants in separate tufts, stems antheriferous in 

 their upper half ; perigonial leaves acutely divided 

 above into three incurved unequal teeth, each leaf en- 

 closing one to four anthers. Female flowers terminal, 

 without proper pericha^tium. The calyces, which 

 contain only pistilla, arc pear-shaped, but, when full 

 grown, nearly cylindrical, depressed above, and 

 terminating in a narrow tubular, ciliated mouth ; 

 destitute of furrows or folds, the transverse section 

 always circular. Calyptra obovate, narrower than 

 the calyx, and perfectly free. Peduncle thicker 

 than in /. bidcntata. Capsule smaller, more spheri- 

 cal, the valves of a deep purplish brown hue. Seeds 

 slightly smaller, and spiral filaments shorter. 



The fructification of/, scutata differs, in that it is 

 lateral, with a perichaitium of two to six leaves, en- 

 tire,orvariously cut at the extremity,and far smaller 

 than the stem leaves, and the calyx is obovate with 

 a trigonous toothed mouth. The calyptra is of equal 

 width with the calyx, and adheres to its sides.

Stem ascending, rooting without flagelli ; 

 leaves bifarious, spreading, acutely emarginate, 

 bilobed, lobes erect, obtuse, incurved; stipules 

 bipartite, awl-shapcd, entire.
