11. The statement that the first kataphyll represents a 
second cotyledon is disproved by the fact that it only makes its 
appearance after germination, and that some species have two 
(p. 13). 
12. For the second of the above reasons it alsé follows that 
the anatomy of Asparagus seedlings does not support the view 
that the cotyledon is a leaf (p. 13). 
Ruscus, Danae, and Semele (p. 14). 
13. The embryo is shorter and broader but in all other respects 
resembles that of Asparagus (p. 15). 
14. The germination is almost identical in all three genera, 
and differs from that of Asparagus in the larger number of more 
sheathing basal kataphylls ; in the less dominant axis; and in 
the slight elongation of the epicotyl and succeeding hypogeous 
internodes of the primary axis (p. 15).

15. The germination much resembles that of Ruscus ; the 
most interesting deviation is the part played by the tuberous 
hypocotyl in the formation of the fleshy rhizome (p. 16). 
Smilax (p. 17). 
In ripe seed the embryo is very minute sid apres 
undifferentiated (p. 17). 
17. The germination very closely resembles that 3 Asparagus ;
