Series XXV. Santalales 
65 Myzodendracee”: Near the Santalaceee and the Loranthacem. 
66 Santalaces :” Closely related to the Loranthacee in many common 
characters and especially in the dwarfed ovules, in the manner of fertilization 
and in the development of the embryo. It is also near the Myzodendracess 
in the structure of the ovary and in the embryo which is partly imbedded in 
the albumen. Moreover, it is found to be connected with the Grubbiacez and 
also with the Olacacew. So far as morphological features are concerned, its 
relation to the Coniferee is undeniable, as can be seen in a comparison of the 
Anthobolez and the Gnetacez. 
67 Opiliacee : 
68 Grubbiaceew™: This family is somewhat related to the Santalaces in 
the structure of the ovule; but it comes nearer to the Olacacee than to the 
Santalacess in the structure of the ovary. Further, some connection seems to 
exist between the Grubbiaceze and the Hamamelidaces, as can be seen in the 
agreement of Grubbia and the latter family in their anatomical characters. 
69 Olacacez”: Viewed from the position of the ovules, the family comes 
near the Santalaces; but in the presence and arrangement of its sepals and 
petals, it is close to the Icacinacese. The limits of the family vary with the 
view taken of it. If we attach great importance to such a character as the 
integment of the ovules, then the family should be broken up and reorganized 
into many families, as has been done by Van TIEGHEM. 
70 Octoknematacez :— ; 
71 Loranthacee”: If the calyculus passes for a reduced calyx, then the 
family comes into intimate relation with the Vitaces, and in consequence, also 
with the Cornacee and Araliaces. If we regard the organ in question as a 
mere swelling on the apex of a perianth tube, then the Loranthaces should 
be placed near the Proteacess and Santalaces. 
72 Balanophoracee™: The sphere of this family varies with the criteria. 
If we lay much stress upon the arrangement of the andreeceum, it should be
