thickened, no trigones. Stipules distant, appressed to the stem, 

 linear, linear-lanceolate, subulate or bifid and irregular segments 

 often unequal, 3-6 cells long, sometimes with 1 or 2 teeth at one 

 or both sides. Inflorescence cladocarpous, ? branches postical, 

 short, about 3 mm. long. Bracts lax, 3 pairs, trisiichous, inner- 

 most about the size of the leaves, erect, ovate-oblong, canaliculate, 

 from a third to nearly the middle bilobed, segments acute or 

 subacuminate, towards the base 1, 2 dentate; cells elongate, sub- 

 pellucid. Bracteole same as the bracts. Sub-bracts much smaller 

 than the bracts, unequally bidentate, or falcate and entire. 

 Perianth projecting 2 to 3 times its length beyond the bracts, 

 linear-fusiform, cylindrical, trigonous only at the apex, mouth 

 truncate-subconstricted, entire, composed of one layer of cells 

 from the middle to apex, lower half 2 cells, at base 2 to 3 cells 

 thick, near the middle about 90 cells round. Calyptra 2 to 3 

 times shorter, slightly narrower, oblong-pyriform, delicate, at the 

 base 2 to 3 cells thick. Capsule purple, oblong or oblong- 

 cylindrical ; valves linear-lanceolate, composed of two layers of 

 cells. Spores dark reddish-brown, broader than the elaters. 

 Elaters bispiral, same colour as the spores. 



Amenta i postical, perigonial bracts few (3-6)-pairs, smaller 

 than the leaves, oval or orbicular, concave, shortly bilobed, seg- 

 ments subacute, sometimes with a third, short, antical, incurved 

 segment ; bracteole linear or oval-lanceolate, entire or bifid ; 

 antheridia large, solitary, oval-globose.
