The above statement plainly shows that the Parietales are a very heterogeneous 

 group which is related to several other series. Its relations to the Sarraceniales, 

 Rhteadales, Rauales, Rosales, Sapindales, Salicales, Geraniales, Maivales and 

 Centrospermae have been pointed out. It is also allied to the Umbellifloraa, 

 as the Dipterocarpacete are connected with the Coruaceae by the presence of 

 a ring of secretory canals in the medulla - crown in Martinia (VAN TIEGHEM). 

 Moreover, its alliance with the Myrtiflorse is manifested in the analogous 

 features of the Elatinaceas' and the Lythracese (BARTLING) ; of the Passifloracejie 

 and the Thynielaeaceae^, in the receptacle and its effiguratiou, in the frequently 

 stalked ovary, and in many other characters ; of the Loasacea3 4) on the one 

 hand and the Lythracere, Myrtacete (EICHLEE) and Oeuotheraceie on the other 

 (De CANDOLLE and EICHLER). The resemblance which the Parietales bear to the 

 series of the Archichlainydea3 has been fully stated above. It remains to 

 compare them with other series of the Metachlarnydeae. They have some 

 relationship to the Tubiflora 1 , as can be seen in the agreement of the Fouquie- 

 riace{B 5) and the Polenioniace;e in the 3 - celled ovary, in the more or less 

 connate styles, and in the tubiform corolla with stamens at its base. Also 

 they in some measure approach the Ebenales, as the Guttiferae show some 

 analogy in fruit with the Ebeuacea}' , and the Theacese bears some resemblance 

 to the Styracace*. A connection between the Parietales and the Rubiales is to 

 be found in a comparison of the Loasacese 7) on the one hand and the Dipsacaeae 

 on the other (BENTH.-HooK.). Further, the Parietales are allied to the Cucur- 

 bitales, as the Cuctu-bitaceaa^ show some resemblance to the Passifloracese 

 (BENTH.-HooK.) ; to the Achariaceaa 95 , in the gamophyllous corolla ; to the 

 Caricacepe 10) , in the structure of the ovules (VAN TIEGHEM) ; to the Loasaceae 11 -
