160 HEPATIC^. 



quadrate or obloDg-quadrate, guttulate, verruculose, walls thick, 

 angles thickened. Axillary leaf (when stem furcate) acuminate 

 entire, the other segment abortive. On some elongated stems 

 and branches the leaves are more symmetrical, the inflexed auricle 

 disappearing. Stipules none. Branches $ generally very short, 

 postical. Bracts 3 pairs, tristichous, innermost erect, oblong, 

 complicate-bilobed, segments subovate apiculate, partly free, all 

 the margin, except towards the base, minutely, unequally spinu- 

 lose-denticulate ; bracteole similar ; exterior bracts much smaller ; 

 all the bracts and bracteoles without auricles. Perianth large, 

 often about the middle of a rosy-purple colour, apex white, linear, 

 deeply triquetrous-prismatic, mouth broadly truncate, wide, rarely 

 constricted, setulose, teeth 1-4 minute quadrate cells long ; deli- 

 cate texture, composed of one layer of cells, near the middle about 

 200 very small, roundish cells around. Pistillidia about 10, 

 large. Calyptra very delicate. Capsule oblong-globose. 



Androecia terminal or on short postical branches ; perigonial 

 bracts many, closely imbricate, somewhat similar to the leaves but 

 broader ; perigonial bracteoles subulate ; antheridia single, oval.
