Nolanaceae adjust these to Dicarposae, and Primulaceae to Epigynosse. Ebenaceae 

 touch upon Guttiferae, and Myrsinaceae upon Rhamnaceae through the genus Choripetalum. 

 Ericaceae moreover have an evident affinity with Rutaceae, first through Ledum, which 

 may be compared with Phebalium, and secondly through Andromeda, which simulates 

 Corraea.
