Nubrgewebe ihrer Samen Ol und Proteinkérmer enthilt. Ich fasse sie als Unterreihe 
Theinee zusammen. Spiralige Anordnung und unbestimmte Zahl der Bliitenphyllome 
kommt bei mehreren dieser Familien noch vielfach vor; und bei den Ochnacea? kann 
man ebensowohl apocarpe Gyniceen wie syncarpe, teils mit centralwinkelstiindigen, teils ‘- 
mit wandstindigen Placenten antreffen. 
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, 
Rhoeadales, Ranales, Rosales, Sapindales, Salicales, Geraniales, Malvaleg and 
Centrosperms# have been pointed out. It is also allied to the Umbelliflore, 
as the Dipterocarpacee"”? are connected with the Cornaces by the presence of 
a ring of secretory canals in the medulla - crown in Martinia (Van TIncHEM). 
Moreover, its alliance with the Myrtifloree is manifested in the analogous 
“features of the Elatinaces” and the Lythraceze (BARTLING) ; of the Passifloraceze 
and the Thymelwaces”, in the receptacle and its effiguration, in the frequently 
stalked ovary, and in many other characters; of the Toasacese* on the one 
hand and the Lythracese, Myrtacese (EICHLER) and Oenotheraces on the other 
(De CaNnDOLLE and Ercuter). The resemblance which the Parietales bear to the 
series of the Archichlamydez has been fully stated above. It remains to 
compare them with other series of the Metachlamydes. They have some 
relationship to the Tubiflorse, as can be seen in the agreement of the Fouquie- 
riaceze” and the Polemoniaces 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 Guttiferse show some 
analogy in fruit with the Ebenaces”, and the Theacess bears some resemblance 
to the Styracacez. A connection between the Parietales and the Rubiales is to 
be found in a comparison of the Loasacex” on the one hand and the Dipsacaew 
on the other (BENTH.-Hoox.). Further, the Parietales are allied to the Cucur- 
bitales, as the Cucurbitaces® show some resemblance to the Passifloracese 
(Benr.-Hoor.); to the Achariaces”, in the gamophyllous corolla; to the 
Caricacess™, in the structure of the ovules (Van Treauem); to the Loasacese'”
