Ontogeny Elucidates the Double Calyx ofLeandra melastomoides(Miconieae, Melastomataceae)

Two new species of Miconia s.lat. (Melastomataceae) from Espírito Santo, Brazil

“…As described above, the petals of M. quartzicola have what appears to be, depending on the interpretation, either an apical appendix or maybe a double apex. It would be similar to the calyx in Miconieae and also other Melastomataceae, in which each sepal is divided into two portions (one ventral and the other dorsal), both portions vascularized and with a distinct shape (Basso‐Alves et al 2017). Although this feature has not been addressed for the petals in the literature, it has also been observed in other species of Leandra s.str.…”

Novelties in Bertolonia (Melastomataceae) from northeastern Brazil

“…Species of Bertolonia are recognized by the herbaceous habit, scorpioid inflorescences and obtriquetrous capsules, and they inhabit moist, hilly and shaded areas of the Atlantic Forest (Baumgratz 1990). The species within the genus can be distinguished mainly by leaf shape and surface indument, the sepals undivided or with two portions (an internal lamina plus an external tooth; see Basso-Alves et al 2017), petal colour, pore position in the anthers and presence or absence of a connective appendage (Bacci et al 2016a(Bacci et al , b, 2017(Bacci et al , 2018Baumgratz et al 2011;Silva-Gonçalves et al 2016). A recent phylogenetic study (Bacci et al 2020) reinforced that the genus is monophyletic; the same study recovered three major clades within Bertolonia, these strongly correlated to distribution and morphology.…”
