Resumen:
Extrafloral nectaries in Piriqueta and Turnera (Turneraceae). The anatomical and morphological
characters of the extrafloral nectaries were studied in 4 species of Piriqueta, and in 16 which belong to
six of the seven series of Turnera (Turneraceae) that present these glands. They were classified
according to its form and degree of development and a new type of pore was described: foveolate.
Based on morpho-anatomical characters, a probable morphological sequence was proposed. This
would locate the species with flattened EFN and without pores in a lower position; after that, the
species with flattened nectaries and foveolate pores are found; in an intermediate position the elevated
extrafloral nectaries (EFN) - sphericals or hemisphericals as well as cupuliforms were found; finally,
the cupuliform EFN with crateriform or mesetiform pore are found. Several species of diverse series
presented variable characters, being located in an unlike position in the proposed morphological sequence;
species with heterogeneous characters were also observed, being difficult to establish their location in
the sequence.
