52 HEPATIC^. 



the leaf or rather abruptly incurved, prolonged on to the stem, 

 occasionally obsolete, especially where the flowers are wanting; 

 cells medium size, equilatero-hexagonal, except below the middle 

 where they incline to become oblong, rather smooth, walls thin, 

 under ordinary powers (1 inch or f) no trigones are observable, 

 but under the \ inch they are small but distinct ; slightly convex 

 which causes the leaf margin to appear subcrenulate. Stipules 

 delicate, rather less than -J- the size of the leaves, distant, orbicular, 

 subobtusely bifid to the middle, the segments acute or subobtuse. 

 Flowers ? on exceedingly short branchlets, usually with a single 

 pair of leaves, very rarely longer with 4 pairs, usually simple, 

 with no subfloral innovations ; very occasionally there is present 

 a minute microphyllous innovation springing from the base of 

 the flower. Bracts less than ^ the size of the leaves, recurvulo- 

 patent, bilobed to below the middle, lobes slightly complicate 

 lanceolate, acute or obtuse, the postical a little shorter and only 

 half the width ; bracteole lanceolate, narrowly bifid to a J or half 

 of its length, segments acute, connate with the other bract, or 

 free. Perianth distinctly emerging from the bracts for more 

 than double of their length, obpyramidato-pyriforra, depressed 

 at the apex and having a very short slender mucronulate slightly 

 compressed beak ; cells equilatero-hexagonal, pellucid, beautifully 

 reticulated; 5-keeled — the keels having very deep-like wings — 

 occasionally towards the apical margin bordered with a single 

 series of very thin cells. Calyptra half the size, obovate, con- 

 stricted at the base so as to appear shortly stipitate. Capsule 

 globose (not been seen exserted). Androecia very frequently 

 upon short branches ; perigonial bracts 2-5 pairs imbricate, 

 turgidly cymbiform, bilobed, postical lobe rather smaller. Anthe- 

 ridia not known.
