Class DICOTYLEDONER 
Subclass Archichlamydeze 
Series XII. Verticillatce 
46 Casuarinacezre”: So far as the anatomical characters of the family 
are concerned, it is closely related to the Gnetacez ; but if we lay much stress 
upon the character of chalazogamy, it should be connected with the Juglanda- 
cee, the Betulaces, certain Urticaces” and the Ericaces. 
Series XII. Piperales 
47 Saururacee”: Related to the Piperaces. 
48 Piperacee: Allied to the Saururacex. 
49 Chloranthaceze: Related to the Piperaces. 
50 Lacistemacem”: Near the Piperaces. 
Series XIV. Salicales 
51 Salicacess®?: When the resemblance of perianth and inflorescence 
is taken into account, this family is to some extent comparable with the 
Betulaces, and the Myricacese. On the other hand, when we attach importance 
to the structure of seeds and fruit, we should regard the Salicaces as a family 
closely related to the Tamaricacese. Moreover, their relation to the Batida- 
ces is to be found in the presence of the dimerous gynseceum. 
Series XV. Garryales 
52 Garryacese: ‘Their relation to other families is not yet established. 
Series XVI. Myricales 
53 Myricaceze: Related to the Juglandace, Salicacess and Betulaces. 
Series XVIL. Balnopsidales 
54 Balanopsidacere”: They are related to the Euphorbiacew in the 
character of the ovules and approach the Fagacew in the involucre of the 
female flowers.
