hyaline. The dorsal tissue has the usual pores found in the thallus 
and similar chambers in one layer directed obliquely forwards. 
The receptacle arises as a small hemispherical body at the end 
of a shoot, but the main shoot, as pointed out before, often forks 
once or twice before this. The one or two small shoots were seen 
in several cases near the receptacles about the same level. In this 
receptacle, if it remains undivided, a vertical groove is present on 
the anterior surface in which five or six archegonia are produced 
one after another in one row by the apical cell which can he seen 
in vertical longitudinal sections below the youngest archegonium. 
This apical cell in such sections has the usual triangular outline and 
below it a thin ridge appears a little later which joins the growing 
margins of the groove. In the meantime the dorsal tissue grows 
forwards and transforms the groove into a large tubular structure. 
The archegonial neck consists of six rows of cells. If the receptacle 
forks and forms two involucres the grooves containing the archegonia 
are more or less lateral (Fig. 4, g). 
The resemblance to Tnrgionin and Cynthodinm is obvious. If 
the shoot which is to form a receptacle, instead of forming the 
receptacle at once, were to grow a little before producing archegonia 
we would have a fertile shoot and a receptacle of the type of 
Cynthodinm or Targionia. 
The involucre contained only one ripe capsule in all the 
specimens examined, but in several cases two or three sporogonia 
were found in the very early stages. The calyptra is only a single 
layer of cells. The sporogonium resembles that of Targionia 
(Fig. 4, c ). The foot is pretty well developed ; its cells are densely 
granular and stain deeply. The seta is short, being a mere con¬ 
striction between the capsule and the foot. The capsule is wholly 
like that of Targionia. The wall consists of a single layer of cells 
all of which are strengthened by annular and spiral thick bands. 
The apex of the capsule has some short elater-like cells with annular 
bands only attached to it, projecting below into the cavity of the 
capsule. Three or four short elaters are found fixed at the base of 
the capsule. Similar cells occur also in the capsule of Targionia. 
The elaters are simple or branched, trispiral and on the average 
120/a long. They are fusiform as a rule, but in one case an elater 
was observed with one end expanded. The spores are 36/a in 
diameter, tetrahedral, and densely covered with round papillae on 
the convex side. The spore-mother-cells do not become lobed at the 
time of division. The capsule does not come out of the involucre at
