Autoecious. " Shorter and twice as narroTV as last species, pale, 

 very transparent, shining when dry, nsually more branched 

 and interwoven, remarkably convex, or nearly roundish. Leaves 

 more or less crowded, the front lobe very convex when dry, 

 also overlying, rising abruptly at a nearly right angle from the 

 basilar lobe, very much decurved and well overlapping the stem — 

 ['maxima decurvus, intus caulem valde superans,'] oblique, broadly 

 oval- elliptic, or very bluntly oval. Cellules very smooth, scarcely 

 or not at all chlorophyllif erous, much thickened, with the trigonal 

 spaces very distinct. Amphigastria wide, two or three times as 

 short as the hinder lobe, very convex, subrotund and cleft in the 

 middle, sinus more or less obtuse, with bluntish segments, every- 

 where indented with projecting cells. Colesule always on the 

 lateral branches, slightly projecting, pyriform-clavate, rounded 

 below, enfolding, the upper 4th part 5-plicate, with prominent 

 and more flattened crests, crenulate at apex." — Lindberg.

Autoecious. " Eather rigid, yellowish or very green, always opaque 

 and not pellucid, almost unbranched, and not radiculose. Leaves, 

 front lobe imbricated, hardly or very little overlapping the 

 stem — [' intus caulem vix vel parum superans'] — oblique, ovate- 

 elliptic, roundly-obtuse, quite entire, the lower margin at apex 

 of stem recurved when dry, basilar sac and hinder lobe very 

 small. Cellules covered with minute papillae, closely packed with 

 chlorophyll, slightly thickened. Amphigastria imbricated, 

 4-6 times larger than the hinder lobe, distinctly cordate at the 

 base, not decurrent, ovately-oval, veiy entii'e, cleft in the centre 

 by a narrow and acute sinus, the segments obtuse. Perichaetia 

 on the stem itself, and on innovations from the apex of it." —
