whole), i.e. filaments thick and as wide or wider than anthers, and the absence of glands. On the 
other hand, however, the trinerved to triplinerved leaves, flowers with tepals sericeous inside, 
and persistent in the fruit, suggest a close relation to Cinnamomum. Actually, glands might be 
not absent after all, for the thick stamens of whorl III may be the result of their fusion with the 
filaments.
