Series XLII. Ericales 
235 Clethraceze”: Close relations are to be found in the Ericacem 
and in the Ternstrcemiacess ; but in other respects, it is closely allied to the 
Stachyuracese and Pentaphylacacez. 
236 Pirolacese”: Intimately related to the Ericacen. 
237 Lennoacese”: Connected with the Ericaces and Pirolaces. 
238 Ericacerw”: Certainly referable to the Metachlamydesx; but, when 
special attention is given to the stamens sitting not on the corolla but on the 
disk, one is convinced that there exists an intimate connection between the 
Ericaceze and choripetalous families. But in the more or less united stamens 
which are present in some genera of the Ericaces, the family is related to the 
Campanulaceze. 
239 Epacridacee”: Near the Ericacex. 
°240 Diapensiaceex”: Near the Clethracem, Pirolacese and Hricacez ; and 
also near the Epacridacese in the insertion of stamens on the corolla. Another 
relation exists between the Diapensiaces and the Primulacex, as can be seen 
in a comparison of Schizocodon and Soldanella. The family is more or less 
connected with the Polemoniacez, Loganiacez and Verbenacese-Stilbex. 
Series XLII. Primatales 
241 Theophrastacee”: Approaches the Myrsinacex, Primulaces and 
Sapotacese. 
242 Myrsinacee”: The connection of this family with the Primulacex 
is so close that to separate the one from the other is entirely artificial. ‘The 
family also approaches the Sapotacese in the floral diagram, but in other 
respects, it comes near the Corynocarpacez. 
243 Primulacew”: Related to the Myrsinacex, Plumbaginacer and to 
the Diapensiaceze.
