938 ` REVISION OF THE NATURAL ORDER HEDERACE.E. 
in which it is convineingly shown that the best place to be found for 
that genus is with or near Winteree. This is exactly the position in 
which Zrochodendron has been put by its founders. The two genera 
agree in almost all essential points, viz. their arboreous habit, alter- 
nate, serrate simple and exstipulate leaves, peculiar process of bud- 
ding, apetalous flowers, numerous stamens, 4-celled anthers, many- 
ovuled carpels (at least in two out of the three known species), ana- 
tropous ovules, albuminous seed, and minute embryo; but they differ 
in the carpels being separate in Zupéelis, and almost consolidated 
in Zrochodendron. How far this would affect their being groupe 
together is a matter of individual opinion. In Ranunculacee we have 
genera with free, and more or less consolidated carpels, and in Pa- 
averacee a species, the common garden Poppy, one variety of which* 
has distinct and consolidated carpels in the same flower. I incline to 
think that we have hare. the ide Kona menden of a new Order of 
plants which will } and Magnoliacee, 
and which might be called Tz p RAS 
The two genera I have to propose (Bakeria and Nesopanax) present 
a new feature, combining as they do free petals with an indefinite 
number of stamens, the other polyandrous genera previously known 
having calyptrate petals.
