Shrubs or trees, with the floral characters of Primulacece, i. e. stamens of the 

 number of the petals or corolla-lobes and opposite them, undivided style and 

 stigma, and a one-celled ovary with a free central placenta, bearing few or 

 numerous peltate amphitropous o\'ules. These are generally immersed in the 

 placenta, and only one usually matures into a seed. This is globose, with a thin
