parietal placentas, in the small seeds, in tlie deliiscence of the fruit and in 

 the leaf-shape. 



211 AncistrocladaceSB ^^ : Tliis family is somewhat related to the Com- 

 bretaceae, Malpigliiaceae, Symplocaceae, Myristicacese and Anonacese in one point 

 or another. Planchon places it near the Dipterocarpaceae, while Bentham- 

 HoOKER and Baillon go a step fm-ther and even assign it to that family. 



Series XXXIX. Opuntiales 



212 Cactaceae ^^ •■ Belated to the Aizoaceae, as can be seen in the 

 floral diagrams of Mesernbriantliemum and Opwdia. 



Series XX. Myrtiflorce 



213 Geissolomataceae^^ : Baillon refers this family to the Celastraceae. 

 Bentham-Hooker assigns it to the Penseacese. De Candolle on the other 

 hand regards it as a distinct family and places it near the Penseacese. 



214 Penaeaceae*^ : Very close to the Thymelseacese. 



215 OliniaceaB^-': Benth.-Hooker assigns tliis family, though with 

 some hesitation, to the Lytliracese. Baillon insists on its being referable to 

 the Khamnaceae. Gilg retains it as a distinct family and refers it to the 

 Thymeleeales, placing it next to the Penseaceae. 



216 Thymelaeaceae^^: In the receptacles and their effiguration and in 

 the often stalked ovaries, this family is comparable with the Passifloracese. 

 But in other respects, it is very close to the Combretaxjeae and Lythraceae. In 

 the cychcal stmcture of the flowers, in the symcarpons gynseceum, and in 

 the absence of albumen, it comes near the Lauraceae. 



217 Elaeagnaceae^^ : Near the Thymelseacese, in the floral structm-e, 

 especially in the receptacles and fruit. Baillon places this family between 

 the Lam*acefe and the Myristicaceae. 



218 Lythraceae^^: Tliis comes near the Myrtacese and Onagraceae, and
