Absence of cyanogenic glycosides in the tribe Miconieae (Melastomataceae)

Biochemical Systematics and Ecology, 2005
Abstract In order to compare ant and non-ant defended species of Melastomataceae, production of hydrogen cyanide gas was tested in the field for 51 species of 10 genera of the tribe Miconieae. Using both the picric acid and the Feigl–Anger tests all populations surveyed tested negative for the presence of cyanogenic glycosides.

Untangling the phylogeny of Leandra s.str. (Melastomataceae, Miconieae)

Molecular Phylogenetics and Evolution, 2016
Phylogenetic studies in Melastomataceae have demonstrated the need for taxonomic rearrangements in the current classification. Nonetheless, melastomes are among the most diverse groups of plants and several cases of known artificial taxa have been observed and awaiting further resolution. The Leandra s.str. clade, with ca.

Evolution of the Sandpaper Clade (Miconieae, Melastomataceae)

International Journal of Plant Sciences, 2015
Premise of research. The Sandpaper clade comprises a group of taxa endemic to the Greater Antilles and forms a subgroup of a larger Caribbean assemblage of Miconieae. Numerous species within this monophyletic group share striking morphological characters and thus traditionally have been considered close relatives.

Comparative seed morphology of Leandra (Miconieae, Melastomataceae)

Brittonia, 2009
The seed morphology of 79 species of neotropical Miconieae (Melastomataceae) is presented. These species have been chosen, in majority, from the polyphyletic genus Leandra. A few other species from the polyphyletic genera Miconia, Ossaea, and Clidemia were also sampled, because of potential similarities.

Untangling inflorescences in Miconieae (Melastomataceae): development, typology, and the systematic and evolutionary implications

Journal of Plant Research, 2022
This study aimed to describe the origin, position, development and typology of inflorescences in Miconieae through ontogenetic and morphological analyses using light microscopy. We observed three morphological character states: terminal, pseudo-axillary and axillary; and two ontogenetic states: terminal and axillary.

Taxonomic notes on Leandra (Melastomataceae, Miconieae) - II

Phytotaxa, 2018
(Taxonomic notes on Leandra (Melastomataceae, Miconieae) - II). In this study we propose 12 synonyms, 15 lectotypes and a new name for eastern Brazilian species of Leandra. Leandra pubescens var. tomentosa is placed in the synonymy of Clidemia atrata; Leandra laxa in the synonymy of L. eriocalyx; Leandra sessiliflora in the synonym of L.

Patterns of Diversification of Miconia (Miconieae) in the Greater and Lesser Antilles

2022
Miconieae are the largest tribe in the family Melastomataceae with ca. 1900 described species. The Greater and Lesser Antilles harbor an impressive number of species from the Miconieae, which occur throughout the islands. Four major clades of Miconia are represented in the Antilles, the Caribbean, Chaenopleura, Mecranium, and Sagraea clades ...

Replacement names and synonyms in Miconia (Melastomataceae: Miconieae)

Phytotaxa, 2012
The name Miconia grandifolia Ule is a later homonym of M. grandifolia D.Don. We replace Miconia grandifolia Ule with Miconia grandifoliata. Miconia anderssonii Wurdack is another name that must be considered as previously occupied, even if the previous name, Miconia andersonii Fawc.

Miconia walterjuddii (Miconieae: Melastomataceae), a new species from Cuba

Brittonia, 2011
Miconia walterjuddii, a new species of Melastomataceae from the mountains in northeast Cuba, is described. This species can be easily assigned to Miconia section Chaenopleura due to its short anthers that open by two longitudinal slits. Sequence data from nrITS confirm this placement.
