somewhat asymmetrical through union at a higher level on one side than 
on the other. The vascular bundles are slightly displaced towards this side, 
but the transition is normal. 
Anemone vernalis has a distinct cotyledonary tube, in which union of 
the cotyledons takes place on one side first, and rearrangements occur as the 
bundles turn inwards at the node. This species shows very markedly the 
early (i. e. high) union of the phloem groups, together with the wide 
and indeterminate grouping of the protoxylem elements In the upper part 
of the hypocotyl. 
Anemone Montana shows the usual features very distinctly. The early

phloem grouping and late protoxylem aggregation of A. vernalis is seen in 
this species also. 
Anemone alpina possesses a short cotyledonary tube or sheath, in 
which the strands are markedly double (Text-fig. 3). As the Individual 
examined was rather older than the members of other species, it is possible 
that the doubleness may be, to some extent, an age phenomenon. The result 
Is a much closer resemblance to members of the Rhoeadales cohort than is 
seen in other species. 
Anemone nemorosa. In the quite young stage the seedlings of this 
species are normal (Text-fig. 4), but very soon become swollen up in 
a tuberous manner, so that the conducting tissues in some cases become
