This genus is in habit and most other characters closely allied 
to Tarenna, but the flowers are usually pentamerous and there are 
often more than two ovules in the ovary. The corolla-lobes are 
imbricate and not twisted. It is usually put in the first series, 
the many-seeded Rubiacece, but has no relations to any other of 
that section.
