FLORA VITIENSIS. 235 
Other important differences have not been observed. All this leaves no doubt that the two genera in 
question are indeed more closely related to each other than they are to any allied Order, and that they 
possess that degree of affinity which justifies us in regarding them as belonging to one and the same 
Natural Order.” 
“ Under these circumstances, the establishment of the independent Natural Order Trochodendree, to 
be ranged with the other Polycarpee, appears to be perfectly justified, and as, in comparing them with the 
other Polycarpee, we have merely to keep in mind the Magnoliacee, Winteracee, and Schizandree, we ob- 
tain absolute differential characters, and a distinct habit. We may be allowed to lay considerable stress 
upon the want of floral envelopes, this character being constant also in Ewpfelia. We must also attach im- 
portance to the epitropous nature of the ovules (to which Agardh justly assigns great systematie value), 
meeting with it in Trochodendree, and not finding it in the three Orders with which we have compared them. 
If we add to these the differences which they respectively present, as, for instance, the want of stipules 
as contrasted with Magnoliacee (quite apart from the spathe-like development, the lower and higher leaf- 
formation of this Natural Order), and the want of oil-cells, so widely diffused in the Winteracee and Schi- 
zandree, even in their foliage and bark,—if, finally, we take into consideration the distinct habit of the Tro- 
chodendree as expressed by their serrated leaves, we shall have good evidence in favour of the above con- 
clusions.” 
“ It remains for me to express my thanks to Dr. Seemann, for kindly reminding me to examine the 
structure of the wood of Hupfelia, with the view of ascertaining how far it agreed with that of Trochoden- 
dron described in my paper. In complying with his wish, I found that Euptelia had the usual structure of 
deciduous woods,—a close dotted prosenchyma, traversed by numerous net-like vessels without any ob- 
servable peculiarities, and without any special characteristics agreeing with those of Zrochodendron. We 
have here the same evident differences of anatomical structure as in the allied Winteracea between Illicium 
and Drimys, and an additional proof that botanical affinities and internal structure do not always go 
together." ;
