insist upon the existence of a relationship between the Moringacese and the 
Geraniales. Pax considers that it is probably best to regard the family as a 
middle member between the Rhceadines and the Leguminose. 
Series XXXI. Sarraceniales 
111 Sarraceniacez”: Clearly related to the Droseraces in floral struc- 
ture. The family is placed near the Papaveraceee by BENTHAM and HooKER on 
account of the staminal cycles and styles. On the other hand its relation to 
the Nymphzacezx 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, Macrarnanz” inclines to look for even 
closer natural affinity with the Cistifloree than with the Papaveraces and 
Nymphzacex. 
112 Nepenthacee”: R. Brown, Bronentart, Livk and ENpLICcHER 
put this family close to the Cytine and Aristolochiacese, which agree with 
the Nepenthacese in the perianth, in the entrorse anthers, in the many-seeded 
capsules and probably in the stigmata. LINDLEY, GrisEBacH and ErcHLrr 
place it near the Droseracese and Sarraceniaceze in consideration of the fruit 
and seeds. The Nepenthacese and Sarraceniaces have considerable affinities 
with the Droseracese, and all of these seem to stand in a position intermediate 
between the Papaveracess and the Cistacese”. 
113 Droseracee™: As far as the hypogynous insertion and the parietal 
placenta are concerned, the family is comparable with the Cistaceze and Vio- 
laces ; but in the perigynous insertion and in the locular ovary (of some 
species of the family) it comes rather close to the Saxifragacez. 
Series XXXII. Rosales 
114. Podostemonaces”: It seems reasonable to believe that the family 
is related to the Saxifragacem, as there is agreement in the hypogynous and
