Fig. 35 bis. Embryogeny in Cardioinanes renifonne 



A, Section across a marginal cushion, showing archegonia on both sides (x 120). 

 B L.s. of a two-celled embryo, the partition wall running obliquely in the plane at 

 right-angles to that illustrated. C, L.s. of a two-celled embryo showing an almost 

 vertical partition wall. D, L.s. of an anomalous embryo. E, Four-celled embryo m 

 l.s. (the arrow indicates the position of the archegonium neck). F, L.s. of an older 

 embryo, about the stage when the leaf initial cell can be distinguished (Figs. B-F, 

 X 220). G, Still older embryo showing initials of the first leaf and of the endogenous 

 root; the shoot apex, not seen in this section, would lie just to the left of the leaf 

 apex; note also the considerable foot ( x 175). H, Fully formed embryo showmg 

 the considerable foot and the shoot apex, leaf, root and incipient vascular tissue 

 (X 150). (All after Holloway; Figs. H and G have been inverted by the present
