upon the criteria adopted. It is useless asking which is the better or more 

 natural position. 



Series XXXVI. Khumnnles 



173 Rhamnaceae ' Nearest akin to the Rhamuacene are the Vitaceee ; 

 after wliich come the Celastracea?. They are also compared with the Oli- 

 niaceae (Myrtiflora?) by BAILLON. 



174 Vitaceae '^ ' Iu floral structure these come quite close to the Rharn- 

 uacea?. Another closely related family which may be pointed out next to 

 the Rhanmacea?, is that of the Umbellifera?, perhaps more closely allied to 

 the Vitacea?, if we put aside the difference in the relative position of petals 

 and -stamens. 



Series XXXVII. Malt-ales 



175 Elaeocarpaceae : Intimately connected with the Tiliaceoe. The 

 family is also related to the Flacourtiacea?, as can be seen in a comparison of 

 Prockia and HasscUia.^ It is, therefore, regarded by some authors, as a family 

 intermediate between the Malvales and the Parietales. 



173 Chlaenaceae^: DE CANDOLLE refers this family to the Malvales. 

 BAILLON places it near the Theacere or even assigns it to the latter family. It 

 is nearer to the Tiliaceas than to the Malvales, in so far as the constant dithe- 

 cous stamens are concerned. It is also comparable with the Dipterocarpacea?. 



177 Gonystylacese' : Related to the Tiliacepe in its anatomical and 

 morphological characters. 



178 Tiliacese 7) : Connected with the Malvacere, Sterculiacese and Chlffi- 

 iiaceae of the Malvales. Also with the Theacese, Dipterocarpacese, Bixacese 

 and Flacourtiacese of the Parietales. 



179 Malvaceae f) : These stand quite near the Bombacacea?, Sterculiacea? 

 and Tiliaceae. But, in the hairy seeds, in the curved embryo and in the 

 secondary meristem in the xylem, they are closely related to the Convolvulaceae.
