Lavoisiereae: A Neotropical Tribe with Remarkable Endemism on Eastern Brazilian Mountaintops

Systematics of the Trembleya sensu stricto clade of Microlicia (Melastomataceae, Lavoisiereae)

“…250 spp. ; Versiane et al 2021;Pacifico and Almeda 2022). However, this tribe has a complex taxonomic history and its current generic delimitation has been drastically modified in light of molecular evidence (Fritsch et al 2004;Rocha et al 2016;Versiane et al 2021).…”

Two new narrow endemic species of Microlicia (Melastomataceae, Lavoisiereae) from Serra do Porco Gordo, Bahia, Brazil

“…Woodgyer and Zappi 2005, Almeda and Martins 2012, Pataro et al 2013, Jesus et al 2018, 2020a, b, 2022b, Romero and Woodgyer 2018, Gali et al 2022. Within Lavoisiereae, species of Microlicia are recognized by their perennial woody habit associated with diplostemonous, mostly heteranthous flowers, elongate to somewhat reniform seeds with a reticulate-foveolate testa, and a base chromosome number of x = 12 (Versiane et al 2021, Pacifico andAlmeda 2022a).…”

“…One of the largest genera of Neotropical Melastomataceae, Microlicia D.Don (ca 250 spp.) (Lavoisiereae) has more than 90% of its species endemic to Brazil (Versiane et al 2021, Pacifico and Almeda 2022a). It is a typical floristic element of mountains with campo rupestre vegetation (rupestrian grasslands), a long‐neglected Brazilian mountainous ecosystem with nutrient‐poor soils and remarkable rates of plant endemism (Versiane et al 2021, Pacifico and Almeda 2022a).…”

In northeastern Brazil, this ecosystem is best developed on the Chapada Diamantina, a mountain range with unique species‐rich flowering plant communities forming a distinct biogeographic province (Colli‐Silva et al 2019), and a major area of endemism for Microlicia (Pacifico et al 2020).…”

“…During the last three decades, studies on the Bahian species of the genus have mostly been limited to species checklists (Zappi et al 2003, Santos and Silva 2005), an identification key (Woodgyer 2005), regional taxonomic treatments (Woodgyer and Lughadha 1995, Pataro et al 2017) and descriptions of new taxa (Wurdack 1995, Woodgyer and Zappi 2005, 2009, Almeda and Martins 2012, Pataro et al 2013, Jesus et al 2018, Pacifico and Almeda 2018, 2020a, b2020b, 2022b, Romero and Woodgyer 2018, Gali et al 2022).
