somewliat oomparable witli the Pimicacea?. The Lytliracese come near the 

 MelastomataceaB in the tube-Uke receptacles. 



228 Oenotheraceae^^ (=Onagrace8e) : Related to the Lythracese ; also to 

 the Halorrliagacese, by the Trapese. 



229 Halorrhagaceae ^^ ■ Intimately related to the Oenotheracese in the 

 floral structnre, and in the anatomy of the stems. Moreover, the family is 

 somewhat comparable with the Chlorantliacese in the reduced form of Hippuris. 

 It also bears some resemblance to the Callitrichaceae. In respect of the en- 

 dosperms, the family approaches the UmbeUiflorae, especially the Comaceae^^ 



230 Hippuridaceae ^^ : The relation of tliis gimip is mentioned in the 

 preceding family. Near Oenotheraceae and Chlorantliaceae. 



231 Cynomoriaceae ^^ : Near the Halorrhagacege.

232 Araliacese"-': Very near the UmbeUiferse. The numerous stameus 

 and carpels in some of the Arahacese clearly show the intimate relation be- 

 tween the family and the MjTtaceae. 



233 Umbelliferae'^-^ ." Quite close to the Ai-ahaceae and the Cornaceae. 

 In other respects, the intimate relation of the family to the Bubiaceae is boyond 

 question. It is also clearly connected with the Vitacese through the Arahacese. 



234 Comaceae^^ : On the one hand tliis family is allied to Caprifohaceae 

 by Carnm, wliile ou the other, it is connected with the Arahaceee by Madixia, 

 Davidia, and CmiMa. All of the Cornese are related to the CaprifoKacese in 

 certain cliaracters; but in other characters, to the Arahacese.
