“…The Livshultz et al (2007) analysis included the genus again in the Malouetieae clade (although with low support), but because of its uncertain affinities, Endress et al (2007) elected to treat Galactophora as a genus incertae sedis within Apocynoideae. With respect to its habit and morphology, Galactophora is rather unusual within Apocynoideae: it is described as a woody herb or erect shrub up to 50 cm growing in periodically flooded white sand savannas, and its sticky glandular hairs on the stems, leaves and inflorescences are unique in the family (Morales, 2005). The Galactophora sample that we have observed was narrower (3 mm in diameter) than the bulk of our remaining material, thus hampering comparison.…”

This study contributes to our understanding of the phylogenetic significance and major evolutionary trends in the wood of the dogbane family (Apocynaceae), one of the largest and economically most important angiosperm families. Based on LM and SEM observations of 56 Apocynoideae species-representing all currently recognized tribes-and eight Periplocoideae, we found striking differences in vessel grouping patterns (radial multiples vs. large clusters) between the mainly nonclimbing apocynoid tribes (Wrightieae, Malouetieae, Nerieae) and the climbing lineages (remaining Apocynoideae and Periplocoideae). The presence of large vessel clusters in combination with fibers in the ground tissue characterizing the climbing Apocynoideae and Periplocoideae clearly contrasts with the climbing anatomy of the rauvolfioids (solitary vessels plus tracheids in ground tissue), supporting the view that (1) the climbing habit has evolved more than once in Apocynaceae, (2) the three nonclimbing apocynoid tribes are basal compared to the climbing apocynoids, and (3) Periplocoideae belong to the crown clade. The wood anatomy within the nonclimbing and climbing lineages is rather homogeneous, although a combination of specific characters (e.g. presence of septate fibers, axial parenchyma distribution, abundance of uniseriate compared to multiseriate rays, and presence and location of prismatic crystals) may be used to identify several tribes.

“…These three infrageneric classification systems differ as to the composition of each section, have nomenclatural problems, were based only on morphological characters, and have never been evaluated using molecular data. New species have been described by several authors over the years, and many others have been reduced to synonymy (e.g., Woodson, 1939Woodson, , 1948Woodson & Schery, 1940, 1942Gentry, 1974;Markgraf, 1975;Morales, 1996Morales, , 1997aMorales, , 2004aMorales, , 2004bMorales, , 2004cMorales, , 2006Morales, , 2007aMorales, , 2007bMorales, , 2010Morales, , 2011Morales & LiedeSchumann, 2016), adding to the current infrageneric confusion.…”

Mandevilla Catimbauensis (Apocynaceae), a New Species From the Semi-Arid Region, Pernambuco, Brazil

Mandevilla (Apocynaceae) is a neotropical genus which is well represented in Brazil. A recent taxonomic revision of the Brazilian species of Mandevilla subgenus Mandevilla included eight new species, one of them from the State of Pernambuco. Nevertheless, while preparing a survey of Apocynaceae from the Brazilian semi-arid region, a new species of the subgenus was recognised. Mandevilla catimbauensis Souza-Silva, Rapini & J.F.Morales is here described and illustrated. It is a twining plant with elliptic, glabrous leaves and hypocrateriform, purple flowers, known only from the Vale do Catimbau National Park, in the State of Pernambuco.
