NATURAL OEDERS. 139 



Prodronius Florae Novae Holland!^, I had it particularly in 

 view to exclude Phytolacca, Rivina, Microtea, and Petiveria, 

 which I even then considered as forming the separate family 

 now for the first time proposed. 



In ChenopodecB the stamina never exceed in number the 

 divisions of the perianthium, to which they are opposite. In 

 Pliytolacece they are either indefinite, or when equal in num- 

 ber to the divisions of the perianthium, alternate with them. 

 This disposition of stamina in Phytolacese, however, uniting 

 genera Avith fruits so different as those of Phytolacca and 

 Petiveria, it would be satisfactory to find in the same order 

 a structure intermediate between the multilocular ovarium 

 of the former and the monospermous ovarium, with lateral 

 stigma, of the latter. 



Two plants in the herbarium from Congo assist in estab- 

 lishing this connection. 



The^r*^ is a species of Phytolacca, related to P. abys- 

 sinica, whose quinquelocular fruit is so deeply divided, that 

 its lobes cohere merely by their inner angles, and I believe 

 ultimately separate. 



The second is a species of Gisekia, a genus in which the 

 five ovaria are entirely distinct. This genus is placed by [iss 

 M. de Jussieu in Portulacacese ; but the alternation of its 

 stamina with the segments of the perianthium, a part of its 

 structure never before adverted to, as well as their insertion, 

 seem to prove its nearer affinity to Phytolacca.^ 



Still, however, the lateral stigma, the spiral cotyledons, and 

 want of albumen in Petiveria, remove it to some distance 

 from the other genera of Phytolacese, and at the same time 

 connect it with Seguieria, with which also it agrees in the 

 alliaceous odour of the whole plant. 



The affinity of Seguieria has hitherto remained unde- 

 termined, and is here proposed from the examination of 

 three species lately discovered in Brazil, one of which has 



^ Ancistrocarpus of M. Kunth (Nov. Gen. et Sp. PL Orb. Nov. 3, p. 186) 

 belongs to Phytolacese, though its stamina are described to be opposite to the 

 segments of the calyx: and it is not improbable that Miltus of Loureiro (Plor. 

 Cochin, p. 302) whose habit, according to the description, is that of Giselcia, 

 from which it differs nearly as Anoislrooarpus does from Microtea, or Rivina 

 octandra from the other species of its genus, may also belong to this order.
