131 Pandaceae^^ : Tlie relation is not yet very clear. 



Series XXXIV. Geraniales 



132 Geraniaceae ^^ : Related to the Linacese and Kutacese, in the 

 nnmber of carpels and ovnles. 



133 Oxalidaceae ^^ : Intimately allied to tlie Geraniacese. Tlie family is 

 also comparable witli tlie Zygopliyllaceae and Kutacese, as sliown by De Candolle. 



134 Tropaeolaceae*^ : In floral structure closely connected with the 

 Geraniacero and its allies. The family also resembles the Hippocastanaceae 

 in the obhque jxDsition of the gyneeceum'^^ 



135 Linaceae*'-' : Some affinities of this family are found in the Gerani- 

 acese, OxaHdacese and Caryophyllaceae-Silenese ; also in the Theacese, as can be 

 seen in the many-membered androeceum of the Hugoniese (Linac.) 



136 Humiriaceae^^ : Near the Linacese. 



137 Erythroxylaceae^'' : Bentham-Hooker and Baillon put this family 

 beside the Linacese; wliile JussiEU, Martius and Eichler regard it as near 

 akin to the Malpigliiaceae, on account of the structm-e of the flowers, especially 

 of the 3-celled ovary. 



138 Zygophyllaceae "^ : Near the Butacese. 



139 Cneoraceae ^"^ : Neai- the Zygophyllaceae. 



140 Rutaceae^^^: Ilelated to severaJ families, such as the Burseracese,. 

 Cneoracese and Zygophyllaceae of the Geraniales, this family is especially 

 aUied to the Simarubacese, as is seen in the agreement of the Dictyolomese 

 (Rutacese) and the Simarubacese, in the stamens provided with scales at the 

 base. The Flindersieae of the Butacese are related to the Meliacese in the fr-uit.- 



141 Simarubaceae^'-': As above. Intimately allied to the Rutacese.
