We find this little tree, Guettarda platypoda DC. (Rubiaceae), regularly in the dune forests embedded in the large mangrove belt of the Amazon coast. Like in many Rubiacs, each tree belongs to one of two morphs, bearing or flowers with short or with long styles. The mechanics of pollination are different for the two ±morph-incompatible types, promoting outbreeding and enhancing genetic diversity in the population. #Rubiaceae #Guettarda #heterostyly #Amazonas #mangroves #dunes #pollinator #trees

Coutarea hexandra (Jacq.) K.Schum. (Rubiaceae) is a small tree with beautiful, sweet-scented flowers opening at night. Bark extracts are used in popular medicine in the Amazon and elsewhere but there is certainly also some potential to use this species as an ornamental. This treelet is flowering for the first time (planted less than two years ago). #botany #moonlight #Amazonas #Rubiaceae #trees #flowers
