“…Only mimosoid flowers with whorled polymerous gynoecium can be called truly polysymmetric in all floral whorls. In this case, all carpels are oriented towards the center of receptacle with their clefts (reviewed in Sinjushin 2014;Paulino et al 2014).…”

Most papilionoid legumes (Leguminosae) are characterized by zygomorphic flowers. Features of monosymmetry are inherent to all floral whorls. We compare flowers of two species of papilionoid legumes with anomalously radialized corollas. Except for vexilloid mode of all five petals, these flowers were remarkable with their free androecium and (in case of Clitoria ternatea) actinomorphic calyx. The symmetry of the gynoecium remains unaltered. These correlations point at a strong interrelation between perianth and androecium symmetry control, possibly governed by the same genes. A review on floral symmetry in related papilionoid genera indicates that staminal fusion is only possible in case of a discernible adaxial petal (flag). This rule has some exceptions which contribute to the idea of independent recurrent origin of monosymmetry in different leguminous clades.

“…For example, this trait has also been reported in Cassia fistula and a few other species such as Amherstia nobilis, Bauhinia malabarica, Ceratonia siliqua, of the caesalpinioids s.l. Furthermore, the trait is even more frequently found in the mimosoid genera Inga and Archidendron (Paulino et al 2014). Kumar and Lal (1989) suggested that this variability could be attributed to a teratological phenomena and/ or possible chromosomal rearrangements or mutations.…”

Senna andhrica P.V. Ramana, J. Swamy and M. Ahmedullah, a new species from Andhra Pradesh, India, is described. The species is remarkable in having unifoliolate, oblong or ovate leaves, 2–3 carpellate gynoecium and reniform seeds. It is the second described species with unifoliolate leaves in the Cassiinae. In most other morphological characters, it is closely allied to Senna occidentalis (L.) Link.

Evolutionary Developmental Biology (Evo‐Devo) Research in Latin America

Famous for its blind cavefish and Darwin's finches, Latin America is home to some of the richest biodiversity hotspots of our planet. The Latin American fauna and flora inspired and captivated naturalists from the nineteenth and twentieth centuries, including such notable pioneers such as Fritz Müller, Florentino Ameghino, and Léon Croizat who made a significant contribution to the study of embryology and evolutionary thinking. But, what are the historical and present contributions of the Latin American scientific community to Evo-Devo? Here, we provide the first comprehensive overview of the Evo-Devo laboratories based in Latin America and describe current lines of research based on endemic species, focusing on body plans and patterning, systematics, physiology, computational modeling approaches, ecology, and domestication. Literature searches reveal that Evo-Devo in Latin America is still in its early days; while showing encouraging indicators of productivity, it has not stabilized yet, because it relies on few and sparsely distributed laboratories. Coping with the rapid changes in national scientific policies and contributing to solve social and health issues specific to each region are among the main challenges faced by Latin American researchers. The 2015 inaugural meeting of the Pan-American Society for Evolutionary Developmental Biology played a pivotal role in bringing together Latin American researchers eager to initiate and consolidate regional and worldwide collaborative networks. Such networks will undoubtedly advance research on the extremely high genetic and phenotypic biodiversity of Latin America, bound to be an almost infinite source of amazement and fascinating findings for the Evo-Devo community.

Comparative development of rare cases of a polycarpellate gynoecium in an otherwise monocarpellate family, Leguminosae

Abstract: Polycarpelly arose at least seven times independently in Leguminosae. The polycarpellate condition appears to be correlated with polyandry, and in most instances, it is accompanied by a profound change in floral organization from a closed to an open system.
