presents some analogy with the Tubiflore, as is shown in the Moringaces” 
and Bignoniacess (DALZELL). Thus, the relation of the series is found to be 
not only with the Ranales and the Parietales, but also with the several other 
series, from the Centrosperme all the way up to the Tubiflore. The natural 
position of the series is, therefore, necessarily dynamic. 
Then, come the Sarraceniales”, to which Evauer refers a3 follows :-— 
Eine Parallelreihe der Rhceadales habe ich in den Sarraceniales geschaffen. Die 
Surracerincee: hat man in enge Verbindung mit den Nymphwacee und die Papaveracee 
bringen wollen, und es ist auch ganz gewiss, dass diese Familien in der Anordnung 
der Bliitenteile mancherlei Ubereinstimmung zeigen. Ler spirocyklische Bau der 
Bliiten von Sarracenia erinnert stark an Nymphau; aber die Placentation der Sarra- 
ceniacee ist verschieden von der der Nymphartcee und der Papiverucea?; die vorherr- 
schend centralwinkelstiindigen Placenten der Sarraceniales sind es auch, welche diese 
Reihe von den Rheadules unterscheiden. 
But, the real relations of this series to other series are manifold. Its relations 
to the Ranales, Rhoeadales and Aristolochiales have already been discussed. 
Moreover, it resembles the Rosales, as will be seen in the Droseraces” and 
Saxifragacess (especially in Parnassia) both of which agree in the perigynous 
insertion and in the ovary in the transitional stage. The connection of the 
Sarraceniales with the Parietales is to be found in the Droseraces and 
Cistacese or Violacese in the hypogynous insertion and in the real parietal 
placenta. Thus, the relations of this series to others are rather extensive. Its 
position in the natural system should, therefore, be dynamic. 
Here, next to the Sarraceniales, ENGLER puts the Rosales”, which in its 
relations to other series is rather perplexing. Its relations to the Santalales 
Leitneriales, Centrosperms#, Ranales, Rhceadales, and Sarraceniales have been 
discussed one after another in course. It remains to compare it with other 
series. Its resemblance to the Parietales is most clearly manifested in the 
agreement of the Crassulacee” and El.tinacew” in their isomerous flowers 
(Bronaniart, A. Braun); in the agreement of the Saxifragaces and the 
Eucryphiaces; of the former family and Begoniacex” in the somewhat
