Seedling Structure of Gy mno sperms. II. 205 
(Diagram 5, Fig. 3). These two bundles, within the hypocotyl, quickly 
approached one another, and, as they did so, the rotation became more and 
more marked ; finally they together formed one pole of the triarch root, the 
other two being produced by the bundles of a and b (Diagram 5, Figs. 4 and 
5). From this it is clear that this particular seedling is of some interest ;

the division of the bundle of a , in its apical region, may be looked upon as 
the initial step towards the splitting of this cotyledon to form two seed- 
leaves ; the consummation of which is clearly indicated in the cotyledons 
c and d. 
Series K showed an advance upon the last seedling. There were 
three seed-leaves, one of which was about twice as large as the others.
