 Jungermauia Pearsoni, Spruce, Journal of Botany, n. s. vol. 10 (1881). 



Dioicous, depresso-csespitose, small, lurid green to reddish- 

 brown in colour, apex often with a reddish-purple tinge. Stems 

 flexuose, flaccid, when dry somewhat rigid and brittle, once or 

 twice (rarely more) furcate, sometimes swollen at apex, no pos- 

 tical branches ; radiculose, rootlets few. Leaves almost equal the 

 whole length of the stem, distant, rarely subcontiguous, hori- 

 zontal to patent-divergent, broadly cuneate or subquadrate, seg- 

 ments suberect, subparallel with the stem, somewhat plane, ovate, 

 subacuminate, acute or subobtuse, sometimes the antical lobe is 

 furnished with a small tooth at the base, otherwise margin entire ; 

 texture firm, epidermis slightly rough, cells very small, quadrate 

 or a little elongate, opaque or subpellucid, walls thick, no trigones 

 or thickened angles. Stipules subulate-linear, usually more fre- 

 quent near the ap3x, sometimes wanting. 



Female inflorescence not met with. 



Androecia on the middle of the stem or branches, perigonial 

 bracts larger than the adjoining leaves, swollen at the base, some- 

 times with an incurved antical tooth at the base, antheridia 

 roundish-oval, solitary, stipe long.
