TRICIIOCOLEA. 109 



posed of narrow, elongate cells, about 12 to IG in diameter, cortical 

 cells GO to 70, sliglitly smaller and firmer than the inner, surface 

 clothed with delicate linked branched leafy j^i'ocesses, which 

 resemble tlie last divisions of the leaves ; prostrate or suberect, 

 flexuose, furcate, bi-tripinnate, branches lateral, alternate, some- 

 what distant, ultimate pinna) very delicate ; rootlets wanting, or 

 very few near the base of the stem, pellucid, short, simple. Leaves 

 on main stem somewhat distant, horizontal, imbricate on the 

 branches and crowded into little heads at the ends of the stem 

 and branches, about 3 times wider than tlie stem, conduplicate, 

 unequally bipartite, antical lobe larger, plane or slightly convex, 

 appressed to the stem, divided almost to its base into two lanceo- 

 late segments, which are again divided and subdivided into 

 numerous hair-like processes, which are either straight, curved, or 

 zigzag, and at the apices extremely delicate ; postical lobe divided 

 in a similar manner ; cells medium to rather large in size, oblong- 

 quadrate at the base of the leaf, on the segments oblong-cylindrical, 

 3 to 4 times longer than broad, walls delicate, no trigones. 

 Stipules large, about as wide as the stem or slightly wider, and 

 about half the size of the leaves, subquadrate or roundish, narrower 

 at the base, divided nearly to the base into 3 or 4 linear-lanceolate, 

 laciniate segments, lacinia? hair-like, straight, curved, or zig-zag. 

 Bracts wanting or minute, finely divided, scale-like processes at 

 the base of the perianth. Perianth terminal in the axils of the 

 primary divisions of the stem, oblong-obovate, cylindrical, carnose, 

 composed of about G layers of cells near the base, at one part 

 where it is welded 12 to 15 cells thick, cells narrow, elongate, 

 epidermis hirsute, covered with capillary, branched processes ; 

 before rupture apex covered with about 10 abortive pistillidia 

 mixed with the hair-like processes, mouth wide, irregularly 

 lacerate, segments 5, smooth, cilia projecting over, but produced 

 from the surface of the perianth. Calyptra wanting. Pedicel 

 thick, cortical layer composed of about 140 small dark-walled 

 cells, about 20 cells in diameter, inner larger, increasing in size to 

 the middle. Capsule oval, dark reddish-brown; outer layer 

 slightly papillose, hyaline, thin ; inner layers (several) dark reddish-
