344 Holden. — Observations on Anatomy of Teratological Seedlings. 
ultimate disappearance of the first epicotyledonary leaf on the symphysis 
side, and possibly, in extreme cases, the modification of the leaves at the 
third node. The leaves of the second node are usually not affected. 
6 . The seedlings of the second group may be either syncotylous or 
heterocotylous. In favour of the first alternative there is the position of the 
first epicotyledonary leaf and the character of the epicotyledonary modifi- 
cations as a whole : in favour of the second alternative is the cotyledonary 
morphology, its anatomy, and the possession of a single axillary bud. 
7 . The seedlings of the second group show certain anatomical tendencies 
due to the increase in the relative importance of the lateral and marginal 
strands, which are paralleled to some extent by the lateral strands in many 
seedling Monocotyledons.
