270 GlobulariaCBae "^ : Uudoubtedly related t» tlie Scrophulariaceae and 

 somewliat coinparable witli tlie Myoporacefe. Also related to several other 

 famiHes — i. e. to the Plumbagiuace», iu the preseuce of calcareous scales 

 ou the leaves, to the Dipsacacese iu the iufloresceuce aud fniit, aud finally to 

 the Plautaginacese iu habit. 



271 Acanthaceae ^^ : A close connection is found to exist between this 

 family aud the Biguouiacese. The Acauthaceae are related to the Scrophu- 

 laiiacese, tlu*ough the Nelsonioideae (Aca,uthace8e) which show au agreement 

 with the Scrophulariaceae in habit and iu the numerous seeds. 



272 Myoporaceae"'^ : As close kiu of the Myoporacefe stand, on one 

 side, the Scrophulariacese, aud ou the other, the Verbenacese. To the former, 

 they are related tlu'ough Myoporum, PhoUdla, Bontia, aud •Zomhiana, in tlie 

 structure of the coroUa and anthers, in the reduced ovules, aud in the position 

 aud structure of the latfcer. With th? latter, their conuection is to be found 

 in Oftla (Myop.). The inter-relation of tlie three families is so close and 

 iuvolved that it maj be both right and wrong to leave tlie Myoporaceae where 

 they are, or to break up the family, putting some of the ganera into the 

 Scrophulariacese, and referriug the rest to the Verbenacese. They also staud 

 near the Cordioideae of the BoiTaginace?e, and to the Solanacefe, in the 

 stracture of the fruit. Finally, tliey are somewhat comparable witli the 

 Oleacese, aud witli the Sesameae of the Pedaliaceee. 



273 Phrymaceae '^ : Closely related to the Verbenacese in liabit and 

 infloresceuce ; also to the Scrophulariace» and Myoporaceae iu the erect ovules.

274 PlantaginaC3ae^^ : Doll and Eichler regard this family as a re- 

 duced form of the Labiatiflor?e, tliis opiniou being supported by the theoretical 

 explanation of the floral diagram aud by tlie 2-celled ovary. Tlie family is also 

 related to the Campanulacese tlu"ougli Phjteuma (Campauul.). It comes rather 

 near tlie Goodeniacese and Caudolleacefe ; wliile iu the abseuce of laticiferous
