insist upon the existence of a relationship between the Moriugaceae and the 

 Geraniales. PAX considers that it is probably best to regard the family as a 

 middle member between the Rhoeadineae and the Legumiuosae. 



Series XXXI. Surracaiialcs 



111 SarraceniaceaB 1} : Clearly related to the Droseraceee in floral struc- 

 ture. The family is placed near the Papaveraceoe by BENTHAM and HOOKER on 

 account of the staminal cycles and styles. On the other hand its relation to 

 the Nj'inpliaeaceoa is incontestable, as can be seen in the numerous stamens, in 

 the insertion of the leaves on the stem, in the one-flowered scape and in the 

 spiral arrangement of the sepals. But, MACFARLANE'^ inclines to look for even 

 closer natural affinity with the Cistifloras than with the Papaveraceoe and 

 Nymphreaceoe. 



112 Nepenthacese ;) : II. BROWN, BRONGNIART, LINK and ENDLICHER 

 put this family close to the Cytineoe and Aristolochiacea?, which agree with 

 the Nepsnthaceae in the perianth, in the entrorse anthers, in the many-seeded 

 capsules and probably in the stigmata. LINDLEY, GRLSEBACH and EICHLER 

 place it near the Droseracene and Sarraceniaceaa in consideration of the fruit 

 and seeds. The Nepenthacese and Sarraceniaceae have considerable affinities 

 with the Droseraceae, and all of these seem to stand in a position intermediate 

 between the Papaveraceae and the Cistacese 45 . 



113 DroseraceaB 5) : As far as the hypogyuous insertion and the parietal 

 placenta are concerned, the family is comparable with the Cistaceae and Vio- 

 laceae ; but in the perigynous insertion and in the locular ovary (of some 

 species of the family) it comes rather close to the Saxifragaceae. 



Series XXXII. Resales 



114 Podostemonaceae 6) : It seems reasonable to believe that the family 

 is related to the Saxifragaceae, as there is agreement in the hypogynous and
