We describe here a new species of the genus Cordia, C. nicandroides, from Northern Colombia, characterized, particularly, for its large drupaceous, nuciform fruits, protected by a wide, penta-sided, accrescent calyx. This tree is mainly distributed in humid forests or transition to dry forests, associated with water courses. It has notable affinities with Cordia oncocalyx, an anemochorous species, endemic to the Caatinga and Atlantic Forest biomes of eastern Brazil. However, it differs clearly from C. oncocalyx, first, for its smaller fruiting calyxes (43-15 x 53-56 mm) closely attached to the fruit, compared to C. oncocalyx larger ones (43-80 x 45-75 mm) and not attached to fruits, besides the larger, broadly ovoid fruits (40-42 x 38-40 mm) vs. the C. oncocalyx broadly ellipsoid fruits (17-21 x 16-19 mm). The species' habitat and these larger and more compact fruits, with a rigid and parchment-like calycine envelope, suggest hydrochory syndrome in the type of diaspore dispersal.

Keywords : Anemochory; Auxemma; Boraginaceae; Brazil; Cordia oncocalyx; hydrochory.
