Series XXV. Santalales 



65 MyzodendraceaB^-' : Near the Santalacese aud tlie Loranthacese. 



66 Santalaceae : ^^ Closely related ^io tbe Lorantliaceae iu uiauy common 

 characters and especially in the dwarfed ovules, in the manner of fei-tiHzation 

 and in the development of the embryo. It is also near the Myzodendracese 

 in the structure of the ovary and in the embryo Avhich is partly imbedded in 

 the albumen. Moreover, it is fouud to be counected with the Grubbiaceae and 

 also with the Olacacese. So far as morphological features are concerued, its 

 relation to the Couiferse is imdeniable, as can be seeu iu a comparison of the 

 Authobolese and the Gnetacese. 



67 Opiliaceae : — 



68 GrubbiaceaB ^^ : This family is somewhat related to the Santalaceae in 

 the structure of the ovule ; but it comes nearer to the Olacacese than to the 

 Santalacese in the structure of the ovary. Further, some connectiou seems to 

 exist betweeu the Grubbiacese aud the HamameHdacese, as can be seeu in the 

 agreemeut of Gruhbia and the latter family in their anatomical charactei^. 



69 Olacaceae'*^ : Viewed from the position of the ovules, the family comes 

 near the Santalacese ; but in the preseuce aud arraugement of its sepals and 

 petals, it is close to the Icaciuacese. The hmits of the family vary with the 

 view takeu of it. If we attach great importance to such a cliaracter as the 

 integment of the ovules, theu the family should be brokeu up and reorganized 

 into mauy famihes, as has beeu done by Van Tieghem. 



70 Octoknemataceae : — 



71 Loranthaceae^^ : If the calyculus passes for a reduced calyx, theu the 

 family comes iuto intimate relatiou with the Vitacese, aud in consequeuce, also 

 with the Comacese and AraUacege. If we regard the organ in question as a 

 mere sweUing on the apex of a periauth tube, then the Lorauthacese should 

 be placed near the Proteacese aud Sautalacese. 



72 Balanophoraceae^^ : The sphere of this family varies with the criteria. 

 If we lay much stress upou the arraugement of the androeceum, it should be
