50 HEPATIC^. 



Leaves iiicubous, contiguous or subimbricate, to the plica erecto- 

 patent, afterwards patent to patent-divergent, unequally bilobed, 

 antical lobe obliquely oblong or ovato-oblong, rotundate, slightly 

 concave, at the base subdecurrent, complicate, quite entire, plane, 

 postical lobe 3-7 times smaller, subovate or rhomboid-quadrate, 

 saccate, margin indexed, transverse or subascending, rarely obso- 

 lete. Cells smallish, roundish- quadrate, 5- and 6-angled, near 

 base sliglitly elongate, walls and angles thickened, sometimes 

 trigones distinct. Stipules below smaller and distant, above 

 larger and contiguous, about half the length of the antical lobe of 

 the leaf, about 3 times larger than the postical lobe, ovato-oval or 

 orbicular, bifid to the middle, sinus narrow, obtuse or acute, 

 segments subobtuse or acute, sometimes one lobe acute, the other 

 shorter and obtuse, quite entire, rotundate at the base or cordate, 

 rarely decurrent. Female flowers terminal on the branches or ou 

 stem, and subtended by a simple or repeatedly proliferous innova- 

 tion, or sometimes by a pair of opposite ones. Bracts much 

 longer than the leaves, complicato-bilobed, antical lobe oval- 

 lanceolate, obtuse, margin plane, quite entire, postical lobe about 

 half the size or still smaller, elliptical, obtuse. Bracteole oblong, 

 obovate, narrowly lanceolate or cuneato-lanceolate, cloven to about 

 the middle or deeper, sinus very narrow, segments obtuse. 

 Perianth very slightly emersed, green, pyriform, rounded at the 

 apex, beak short, slightly compressed, 5-carinate, keels small, 

 subobtuse. Androecia on short lateral branches or on stem, rotund 

 or oval, perigonial bracts 5-9 pairs, bilobed to the middle, postical 

 lobe rather smaller than the antical, diandrous.
