or sometimes even broader than long, subconcave, emarginate or 
bifid, and often slightly narrowed at the apex, obscurely margined, 
at least the upper ones, which are much enlarged and more obtuse- 
. lyand less deeply lobed and undulate ; lobes usually very obtuse or 
rounded, but often acute or acutish at the apex, frequently apicu- 
late ; sinus varying from very broad and obtuse in the upper leaves 
to narrow and acute in the lower ones; areolation large and rather 
lax. Amphigastria appressed to the stem and more or less hidden 
among the rootlets, setaceous or subulate, or the uppermost ones 
Sometimes lanceolate, usually composod of 2-3 rows of cellules, 
often, however, of a single row, and not infrequently (the upper 
ones) of 4-6 or more rows, mostly entire but sometimes (the broad- 
er ones somewhat equally, the narrower ones very unequally) bifid, 
mostly with an erect cilia-like tooth on one or both sides at the 
base, the apex incurved. Perianth situated on the back of the tu- 
rion-like apex of the stem (much as in Fossombronia/) vertical and 
at aright angle to the stem, mostly sessile and without involucral 
leaves, rarely short-pedicled, and then with 1-2 leaves on the short 
stalk, obovate-lageniform (suddenly much contracted above the _ 
middle into along narrow neck), somewhat gibbous on the front 
side, the mouth slightly funnel-shaped, ciliate, and at length incised. 
Pistillidia numerous. Antheridia in the axils of enlarged leaves 
hear the apex of the stem and innovations. Although the base of 
the perianth is included between the upper pair of stem-leaves, 
these have no connection with and are arranged without reference 
to it. Their base is fully 2-3 times as broad as the base of the 
perianth and obliquely attached to the stem, and their apex points __ 
in a different direction from that of the perianth. Stemsare found 
bearing perianths of both the present and the previous year’s growth ; 
these contain numerous pistillidia, which, notwithstanding the pre- 
sence of antheridia, are all sterile.
