As at the moment recognised, Leandra contains over 200 species with the best range centred in southeastern Brazil. Leandra varieties a part of the tribe Miconieae, distinguished by flowers with kind of inferior ovaries and fleshy berry fruits. Genera throughout the Miconieae have traditionally been tough to outline; as early as 1891, the Belgian botanist Alfred Cogniaux declared that they had been primarily arbitrary. Leandra was purported to be outlined by its acute petals and terminal inflorescences nevertheless it has not all the time been clear whether or not a given species may be mentioned to own these options or not. It ought to subsequently come as no shock that the genus Leandra proved to be polyphyletic with the arrival of molecular evaluation (Martin et al. 2008). Nonetheless, a big clade centered on southern Brazil has continued to be known as Leandra sensu stricto.
There seem like few if any direct observations of pollination in Leandra however flower morphology and comparability with associated genera means that they’re buzz-pollinated with pollinators taking pollen as a reward (Reginato & Michelangeli 2016b; buzz-pollination referring to pollination by bees the place the bee’s buzzing induces the flower to launch pollen). Apomixis, with seeds being produced straight from ovule tissue with out pollination, is just not unusual and should even be the bulk situation (Reginato & Michelangeli 2016a). Seeds are dispersed by birds feeding on the berries. Many Leandra species seem very localised in distribution and they’re notably various in various excessive altitude areas. Species range of their most popular habitat from disturbed to undisturbed; these species present in undisturbed areas are uncommon parts of the understory, however these present in disturbed habitats could also be among the many most ample shrubs within the space.
