presents some analogy with the Tubiflora?, as is shown in the Moringaease 15 

 and Biguoniacege (DALZELL). Thus, the relation of the series i=5 found to be 

 not only with the Rauales and the Parietales, but also with the several other 

 series, from the Ceutrospermre all the way up to the Tubiflorse. The natural 

 position of the series is, therefore, necessarily dynamic. 



Thau, come the Sarracenialea", to which ENGLER refers as follows : 



Eine Parallel reihe der Rlimadales habe ich in den Sarracenlales geschaffen. Die 

 S'irracejii'K'ea; hat man in enge Verbindiing mit den NymphfHacecK und die Papaveracecv 

 bringen \vollen, land es ist aucli ganz gewiss, dass diese Familien in der Anordnung 

 der Blutenteile mancherlei tjbereinstimimmg zeigen. Der spirocyklische Bau der 

 Bliiten von Sarracrnla erinnert stark an Nympttftui ; aber die Placentation der Surra- 

 cen'acecK ist verscliieden von der der hymplia; icect: und der Papnverncece ; die vorherr- 

 schend centralwinkelstSndigen Placenten der ^arracenia'e* sind es fmch, welche diese 

 Keihe von den lihoeaditle.i iinterscheiden. 



But, the real relations of tliis series to other series are manifold. Its relations 

 to the Rauales, Rhoaadales and Aristolocliiales have already been discussed. 

 Moreover, it resembles the Rosales, as will be seen in the Droseracese^ and 

 Saxifragacese (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 Droseracese^ and 

 Cistacese or Violacase 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, ENGLEE puts the Rosales fi) , which in its 

 relations to other series is rather perplexing. Its relations to the Sautalales 

 Leitneriales, Geutrosperrnfe, Ranales, Rhoeadales, 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 Orassulaceffi'" and EL u tinacese 7) in their isomerous flowers 

 (BEONGNIAET, A. BEAUN) ; in the agreement of the SaxifragaceaB and the 

 EucryphiacesB 55 ; of the former family and Begoniaceie' in the somewhat
