Wuitz, on the one hand, the tendency of recent work has 
to Sn the relationship of the Gymnosperms to the 
Pteridophyta, and, by the recognition of an intermediate group, 
Cycadofilices, to bridge the separating gulf, there is, on the other 
nd, a growing feeling that Angiosperms and Gymiiosparma are 
leas ppemately peeereros than has been implied in their arrange- 
ent a mbers of one great sub-kingdom, Seed-plants or 
Spetmatophytes This ‘tier view finds expression in the mode

account of the Fale i At that time, to quote the preface 
to the present volume, ‘‘ it was our purpose to issue as a second 
part an account of the Angiosperms, which would also scctai 
a complete index of the whole work. We have become convinced,

groups, co-ordinate with peuiophyions: The present volume is 
therefore issued not rg Part ii. of Morphology of Spermatophytes, 
but as an independen ga entitled Morphology of Angiosperms ; 
and any subsequent edition of the previous volume will be entitled 
Morphology of Gymnosperms, In this decision the authors will 
assuredly have the sympathy of some working botanists as well 
as some teachers of science who are in the habit of reflecting 
on the subject- sae which they set before their students.

lectures and laboratory work given at Chicago pares to classes 
of graduate students arenes for research. ile, therefore, it

through papers in sds various publications, some of which are not 
readily accessible, it has the additional advantage of presenting 
statements which have est confirmed by members of the botanical 
staff and by numerous students, whose results have also served to 
contribute no small re of new material. 
In the treatment of the Gymnosperms the great divisions 
were taken separa et ae of their marked differences; in 
Angiosperms, however, there is not that great diversity in special 
morphology such as we find, for instance, between Cycads and
