[Fig. 5J] The Apocynaceae constitute a family of mostly tropical and subtropical plants, with about 415 genera and 4555 species (Stevens, 2013). Their basic number is variable, but x = 11 is considered the likely base number (Van der Laan & Arends, 1985; Albers & Meve, 2001). As far as we know, there is no publication dedicated exclusively to the Brazilian species of Apocynaceae, and only three records are reported for species from Northeast Brazil thus far: 2n = 22 for Hancornia speciosa (Pedrosa & al., 1999) and the unpublished 2n = 20 for Mandevilla tenuifolia and 2n = 22 for Rauvolfia ligustrina (Pitrez, 2006). In this work, we present chromosome counts of 26 species in 14 genera of Apocyncaceae, with emphasis on species from the Northeast Brazil. For the genus Allamanda, the counts revealed the occurrence of diploid, triploid and tetraploid: 2n = 18 and 36 for A. blanchetii, 2n = 18 and 2n = 27 for A. doniana and 2n = 18 for the remaining species. Polyploid cytotypes in Aspidosperma pyrifolium and Rauvolfia sellowi were also observed. The counts of 2n = 18 for Stipecoma peltigera and Temnadenia violacea are the first record for the genera, while the remaining species had their first chromosome counts in this work, except Allamanda blanchetii, A. cathartica, Asclepias curassavica and Himatanthus bracteatus, which had their counts partially confirmed, with 2n = 36 for A. blachetti being the first record of polyploidy for the species. Our counts of 2n = 18 and 2n = 22 confirm the basic numbers x = 9 and x = 11. However, counts of 2n = 20 for most species of Mandevilla suggest the occurrence of dysploidy in this genus. The remaining species are chromosomally stable, except Aspidosperma pyrifolium with descending dysploidy, an occurrence apparently rare in Apocynaceae (Van der Laan & Arends, 1985; Albers & Meve, 2001).

[Fig. 11D] This study was carried out as part of research on annual pansies (Viola sect. Melanium DC.) focused to compare palynological, morphological, and cytological characters, to highlight their systematic implications (Scoppola & Lattanzi, 2012; Scoppola & al., unpub. data), and to update the distribution areas of the Italian species (Magrini & Scoppola, 2013). Literature cited Magrini, S. & Scoppola, A. 2013. Is it possible to define the real Italian distribution area of the annual pansy, Viola kitaibeliana ? Pp. 53–54 in: Peccenini, S. & Domina, G.
