Department of Plant Biology and L. H. Bailey Hortorium, Cornell University, Ithaca, NY 14853. Flowers are five-merous with superior ovaries and have 5 stamens alternating with 5 presumably staminodal nectaries. They are linked by a subset of these attributes.
Fruits are capsules and leaves are folded and have distinctive glands.
These taxa share many characters with modern Ericales and related families including Diapensiaceae, but other possibilities must be considered including families of Sapindales. These species are interesting from the perspective of pollination biology because they have characters consistent with highly derived forms of insect pollination.
