235 Clethracese ^^ : Close relations are to be found iu the Ericaceae 

 aud in the Terustroemiaceae ; but iu other respects, it is closely allied to the 

 Stachjuraceae aud Pentaphylacaceae. 



236 Pirolaceae '^ ■ lutimately related to the Ericacese. 



237 LennoaceSB ^^ .' G>uuected with the Ericacese and Pirolaceae. 



238 Ericaceae*^: Certainly referable to the Metachlamydeae ; but, when 

 special atteution is giveu to the stamens sittiug uot on the corolla but on the 

 disk, oue is comdnced that there exists au iutimate connection betweeu the 

 Ericaceae and choripetalous famihes. But iu the more or less united stamens 

 which are preseut in some genera of the Eiicaceae, the family is related to the 

 Campauulaceae.

240 Diapensiaceae''^ : Near the Clethraceae, Pirolaceae and Ericacese ; and 

 also uear the Epacridaceae in the inseiiion of stameus on the oorolla. Another 

 relatiou exists between the Diapeusiaceae aud the Primulaceae, as can be seen 

 iu a comparison of jSchizocodon aud Sddanella. The family is more or less 

 conuected with the Polemouiaceae, Loganiaceae aud Verbeuaceae-Stilbeae.

 respects, it comes near the Coryuocarpaceae.

 the Diapeusiaceae.
