470 OPHIOGLOSSALES 
The account given by Bruchmann for &. ZLunaria corresponds in 
all essentials to the above, though it differs in certain details. The octants 
appear as usual, and are followed by less regular divisions which disguise 
them in the resulting ellipsoid body. The limits between the epibasal 
and hypobasal parts are lost, and owing to the late origin of the several 
parts of the embryo, Bruchmann found it impossible to refer them

strictly to one or the other source (Fig. 262) The root, which is 
organised early, grows first in a horizontal direction, and bursts laterally 
out from the prothallus, but the remainder of the embryo rests within the 
prothallus, where a distended foot is formed. On this ovoid cellular 
body, and opposite to the neck of the archegonium, there arises the apical 
cell of the axis: it is immediately overarched by a small growth 
(apparently on the same side of the axis as the root), which Bruchmann 
takes for a rudimentary cotyledon. Up to this time the embryo has a 
predominant root—more so than in 2. virginianum—while the foot serves
