Abstract: Species from Utricularia sect. Foliosa and sect. Psyllosperma were studied based on seed characteristics. Our goals were to search for informative characters useful to species delimitations, especially for very polymorphic species such as U. amethystina, and also to provide an identification key and discussion about the delimitation of both sections. The qualitative characters of seeds were more useful than quantitative ones for taxonomic purposes but, as presented here in an identification key, it was impossi… Show more

“…Taylor (1986) proposed sect. Psyllosperma as an apparently "natural" group, even considering the similarity in pollen and seeds (Menezes et al, 2014) between the species of both sections (Psyllosperma and Foliosa). Müller and Borsch (2005) suggested the expansion of sect.…”

“…The extensive geographic range of the genus and also of some species such as Utricularia gibba and U. subulata, which have a pantropical distribution (Taylor, 1989), may be at least partly due to long dispersal by migratory birds, facilitated by the morphology of seedsmost species of Utricularia have diminutive dust-like seeds (Eriksson and Kainulainen, 2011;Menezes et al, 2014) with a very reduced embryo (Płachno and Świątek, 2010).…”

“…These all have showy flowers and are often cultivated as ornamental carnivorous plants. Furthermore, some have formed the subject of embryological (Płachno and Świątek 2012), seed and seedling structure (Studnička 2009; Płachno and Świątek 2010; Menezes et al 2014), ecological (Studnička 2011) and genetic studies (Clivati et al 2012). With the sole exception of U. reniformis (Clivati et al 2014), detailed observations of plant–pollinator interactions are lacking for these species.…”

“…1) remains a matter of debate. Nevertheless, seeds of Utricularia species are tiny (0.2-0.6 mm long) and have large testa cells with a foveolate surface, features that are known to be favorable to the aggregation of air bubbles and thereby facilitating their floatability (i.e., increasing buoyancy in air or water) (Eriksson and Kainulainen, 2011;Menezes et al, 2014). Given these traits, it is likely that seeds were infrequently transported from southern Japan or southern China by strong gusts of wind (e.g., typhoons, which are very common in East Asia) from early summer to autumn, the flowering and fruiting time of U. bifida and U. caerulea.…”
