Two analyses are carried out for a reconstruction of the phylogeny of the large angiosperm
family Rubiaceae. The position of Luculia and Coptosapelta, unresolved or sister to all other …

Next to pollen, stamens of flowering plants often produce microstructures, called orbicules,
lining the locules. Although the existence of orbicules has been known since 1865, their …

In its current circumscription, the herbaceous tribe Spermacoceae sl (Rubiaceae,
Rubioideae) unites the former tribes Spermacoceae s. str., Manettieae, and the Hedyotis …

The Rubiaceae tribe Rubieae has a world-wide distribution with up to 1,000 species. These
collectively exhibit an enormous ecological and morphological diversity, making Rubieae an …

In this study we investigate the large and diverse Rubiaceae–Gardenieae and closely
related tribes Bertiereae, Coffeeae, Cremasporeae, Octotropideae, and Pavetteae. Some of …

Despite extensive efforts, there are unresolved questions on evolutionary relationships in
the angiosperm family Rubiaceae. Here, information from six loci and 149 Rubiaceae taxa …

This study described the systematic classification of Rubiaceous species by investigating
morpho pollinic traits, providing a comprehensive analysis of their diversity and …

Abstract we conducted anatomical analysis of anthers with the aim to establish the
