Abstract:
ABSTRACT Flowers with heterodynamous stamens can present differences in the pollen grains of each stamen size group. Species of Aeschynomene L. present didynamous stamens (five long and five short) but little is known about their pollen dimorphism. The objective of this study was to increase the knowledge about the pollen characteristics in Aeschynomene and emphasize the possible morphological differences between the pollen grains of long and short stamens in order to contribute to ecological and taxonomic studies. Pollen grains from the two groups of stamens size of ten species were analyzed

Abstract:
Stamen dimorphism of buzz-pollinated flowers frequently involves heteranthery, where vibrated, poricidal anthers produce less pollen of lower viability. These anthers often allow for a progressive dispensing of pollen as predicted by the pollen presentation hypothesis. Buzz-pollinated, didynamous stamens of Agalinis lack poricidal anthers but possess staminal trichomes. We quantified pollen characteristics, bee visitation, and foraging behavior (sternotribic vs. nototribic) for three buzz-pollinated species of Agalinis. Single visits to Agalinis auriculata (Michx.)

Abstract:
Abstract—A species previously treated in Staurogyne (S. nitida) is elevated to the category of a new genus of Acanthaceae, subfamily Nelsonioideae, based on morphological and molecular data. The sole species, Aymoreana nitida, occurs in the Atlantic Forest of eastern Brazil, from southern Bahia to northern Espírito Santo. Aymoreana differs from other genera of Nelsonioideae by the combination of the calyx with subequal segments, the slightly zygomorphic corolla, the four didynamous stamens, and the asymmetric gynoecium. Morphological information is accompanied by a molecular phylogenetic tree,

Abstract:
<b>Background and aims</b> – Autonomous selfing is a potential strategy to overcome pollinator scarcity or unreliability, but the specific mechanisms of autonomous selfing need further study to clarify our understanding of this phenomenon. This study investigated the mechanism of autonomous selfing in a subalpine population of <i>Prunella vulgaris</i> (Lamiaceae), a species with didynamous stamens.<b>Methods</b> – We studied the floral biology, pollinator activity, and breeding system of <i>Prunella vulgaris</i> in a natural population. The short stamens and long stamens were removed separatel

Abstract:
Symphyllophyton (Gentianaceae) is characterized by autotrophic herbs, with tetramerous flowers didynamous stamens, filaments attached to the distal portion of the corolla tube and connate-perfoliate or free leaves. The finding of a new population in the Brazilian State of Goiás inspired a detailed and unprecedented study of the genus, which lead to the discovery of four new species in different States and to the repositioning of Schultesia sucreana within the genus, thus elevating the known number of species from two to seven. A lectotype is designated for the genus. Descriptions, illustration

Abstract:
Branched broomrape, Phelipanche ramosa (L.) Pomel (syn. Orobanche ramosa L.), is a chlorophyll-lacking, obligate root parasitic plant that infests Brassicaceae, Solanaceae, and legumes (3). In western France, P. ramosa has invaded oilseed rape fields since the 1990s, causing significant yield losses (1). This crop has now become the primary host for the parasite, along with buckwheat (Fagopyrum esculentum L.), hemp (Cannabis sativa L.), and tobacco (Nicotania tabacum L.). In September 2013, a field survey indicated that a celeriac (Apium graveolens L. var. Prinlz) crop on clay soil in the Cham

Abstract:
Barleria prionitis is a well-known medicinal plant. It has a global use in whooping cough bronchitis, leucoderma, toothache, inflammation and as expectorant. As observed in the field, Barleria prionitis reproduces only by seeds. Over-exploitation from wild source together with the loss of habitats due to anthropogenic onslaughts poses severe threat for sustenance of the species. Therefore, the knowledge of the reproductive ecology of any plant is most essential to formulate suitable strategies for its conservation and cultivation.
