ANTIIELIA. 95 



base, at the middle a little elongate, walls thick, no trigones or 

 thickened angles, composed of two layers of cells at the base, 

 above one layer, upper portion often hyaline. The third postical 

 leaf (stipule) similar to the others, sometimes slightly smaller. 

 Bracts several pairs, more or less crowded, capitate, larger than the 

 leaves, 2 to 3 cells thick near the base, oblong-oval, bilobed to 

 about the middle, sinus narrow, acute, segments ovate-lanceolate, 

 acute or acuminate, margin denticulate, or entire. Bracteole 

 smaller than the bracts, bilobed to about the middle, erose- 

 denticulate. Perianth composed of two layers of cells at the 

 base, one layer and delicate above, near the middle about 100 cells 

 round, free, terminal, projecting about half beyond the bracts, 

 oblong-oval, upper half multi- and deeply plicate, frontally sub- 

 compressed, antically deeply unisulcate, at both sides of the 

 furrow the upper margin carinate, postical 3-(2) carinate, at the 

 apex several small keels added (10-8-plicate), mouth wide or sub- 

 constricted by the folds, laciniate, lacinise denticulate. Calyptra 

 ovoid-globose, 2 to 3 cells thick at the base, pistillidia few (5 or 6) 

 dispersed on the upper portion of the calyptra. Capsule sub- 

 globose, composed of two layers, small, dark brown. Spores pale 

 brown, elaters bispiral about as broad or a little broader than the 

 spores. 



Androecia at the apex or middle of the stem, on separate ones 

 from the ? although often entangled with them ; perigonial 

 bracts 4-6 pairs, somewhat similar to the leaves only a little 

 broader, sometimes slightly denticulate, closely imbricate, sub- 

 secund, ventricose at the base ; antheridia large, single, oval, 

 bearer short.
