Ayenia saligna from Colombia is described and illustrated. It is remarkable for having foliar nectaries, which now are known to occur in seven of the 75-80 species in the genus. The petals of Ayenia are structurally complex and the inconsistent use of terminology to describe their parts is noted. In addition, the relationship of A. saligna to other species of Ayenia is discussed. [ABSTRACT FROM AUTHOR]

A new genus and species of Dipterocarpaceae, Pseudomonotes tropenbosii, from Amazonian Colombia is described and illustrated. This new taxon, which appears most closely related to the subfamily Monotoideae, is the second reported occurrence of a member of the family in the Neotropics. The new entity differs from the rest of the Dipterocarpaceae in the absence of fasciculate trichomes and in having sepals conspicuously aliform (reaching 10-16 cm in length) and one ovule per locule with nearly basal (sub-basal) placentation.
