is to be placed next to the Bixacese (Parietales). It is also to some extent 

 comparable to the Simarubacese (Geraniales). Moreover, the resemblance 

 between the Kceberliniaceae and the Capparidacere is so close that the former 

 is by some authors incorporated into the latter. 



Dichapetalacee i;) (Geraniales) : Some genera with gamopetalous and 

 zygomorphons flowers of the same family are assignable to the Metachlamydese. 

 But in other genera with polypetalous flowers, it agrees perfectly with the 

 EuphorbiaceaB Phyllanthoidepe (Geraniales). Its natural position therefore, 

 shifts from one place to another, according to the different criteria applied. 



Cyrillaceps^ (Sapindales) : This group is related to the Ericaceae in the 

 habit and peculiar anthers of Co&.wi (Cyrill.). In another respect, it is 

 uudeniablly allied to the Aquifoliacene. HOOKER regards it as referable to the 

 Anacardiacea?, while EKGLER looks upon it as a distinct family assignable to 

 the Sapiudales. 



Corynocarpaceaa^ (Sapindales) : This group is referred to the Berberidacese 

 by JUSSIEU and SPRENGEL, while it is assigned to the Myrsinacese by others. 

 VAN TIEGHEM places it near the Geraniaceee. 



Salvadoracee 4) (Sapindales) : This should find its place among the 

 Sapindales near the Celastracese, if we lay great stress upon the choripetalous 

 genera, Azima and Dolcra. But on the contrary, if the gamopetalous genera 

 of the same family preponderate, then it should be placed close to the Oleacese. 



Fouquieriacea3 5) (Parietales) : This is related to the Polenioniacere by the 

 3-celled ovary, by the more or less connate styles, and by the tube-like corolla 

 with stamens at its base ; but, in other characters besides those just givan, it 

 is quite close to the Tamaricacere. 



Winterauacere'" (Parietales) : In the presence of oil-cells in the cortex, 

 pith and leaves, in the general structm-e of the xylem, especially in the 

 tracheids with bordered pits in wood-prosenchyma and in the inconstant 

 number and spiral arrangement of the perianth-segments, this group comes 

 very close to the Magnoliace^ (Ranales). On the other hand, if the connate
