The systematics of Knoxieae (Rubiaceae)—molecular data and their taxonomic consequences

A molecular phylogeny of the Knoxieae group is presented and the morphological support for the resulting groups and the taxonomic consequences of the phylogeny are discussed.

Pollen of African Spermacoce species (Rubiaceae) Morphology and evolutionary aspects

Pollen morphology of 43 African species of the genus Spermacoce has been investigated by scanning electron and light microscopy, and nine pollen types are recognized mainly on the basis of pollen size, aperture morphology and tectum peculiarities.

Gomphocalyx and Phylohydrax (Rubiaceae): sister taxa excluded from Spermacoceae s.s., featuring a remarkable case of convergent evolution

The genera Gomphocalyx and Phylohydrax (Rubiaceae) have been invariably placed in the tribe Spermacoceae s.s. based on the uni-ovulate ovary locules and pluri-aperturate pollen grains. Sequence data

A palynological study of Galium L. (Rubiaceae) in Egypt and its systematic implication

Pollen shape, size, exine ornamentation, number of apertures present powerful characters for distinguishing between species, and the ornamentation was found useful to distinguish among closely related species such as Galium aparine and G. spurium.

Palynological characters and their phylogenetic signal in Rubiaceae

The systematic usefulness of pollen morphology in Rubiaceae is discussed at the (sub)family, tribal, generic, and infraspecific levels, using up-to-date evolutionary hypotheses for the different lineages in the family.

Pollen morphology of Rubiaceae Juss. species occurring in an area of caatinga (dryland) vegetation in Bahia State, Brazil

The palynology of the following 16 species of Rubiaceae, from Brejinho das Amestistas, was investigated and palynological data can be used to distinguish these species.

Can Colpus Membrane Ornamentation be a Reliable Taxonomic Tool? A Case Study with Some Rubiaceous Taxa from Eastern Himalaya

ABSTRACT Due to overlapping in several of the primary pollen morphological attributes (viz. aperture type and exine sculpturing) throughout the subfamilies and tribes of Rubiaceae, these attributes

Systematics, taxonomy and floristics of Brazilian Rubiaceae: an overview about the current status and future challenges

The present work is to offer an overall view of the most recent family classification with emphasis on the genera of Rubiaceae occurring in Brazil, and to indicate particular taxa that are still in need of phylogenetic and taxonomic studies.

The genus Tapinopentas was published by Bremekamp in 1952 and he carefully compared it with Chamaepentas, Parapentas and Pentas, but not with Otomeria, although it seems to me to take an intermediate

Abstract— The sister group of the monophyletic tribe Argostemmateae, including Argostemma and Neurocalyx, is not the tribe Hedyotideae, or a part of it, as earlier assumed, but the monophyletic tribe
