Abstract The tribe Posoquerieae was recently described to include the genera Posoqueria Aubl. and Molopanthera Turcz. based on floral morphology, palynology, the presence of the pollen catapult mechanism, and molecular phylogenetic evidence. The floral morphology of these two genera was first recognized as unique in the Rubiaceae by Schumann. Both genera have stamens initially united into an ellipsoidal structure held at an oblique position, with the ventral stamen that springs forward when… 

Phylogenetic relationships and new tribal delimitations in subfamily Ixoroideae (Rubiaceae)

A revised tribal classification, including the description of five new tribes, Airospermeae, Augusteae, Scyphiphoreae, Steenisieae and Trailliaedoxeae is provided, to resolve the phylogeny and assess the tribal delimitations in the expanded Ixoroideae.

Rubiacearum Americanarum Magna Hama Pars XXVII: Six New Species and a New Taxonomic View of Posoqueria

A new taxonomy based on corolla form and size, the length and symmetry of the filaments, and fruit morphology finds the name P. panamensis (Walp. & Duchass.) Walp.

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.

Sipaneopsis (Sipaneeae, Ixoroideae): A unique flowering process in the family Rubiaceae and its taxonomic significance

The differences in flower morphology and process of anthesis between the two genera provide an important set of significant taxonomic and diagnostic characters that can be used to distinguish them.

Leaf anatomy and micromorphology of six Leaf anatomy and micromorphology of six Leaf anatomy and micromorphology of six Leaf anatomy and micromorphology of six Leaf anatomy and micromorphology of six Posoqueria Aublet species (Rubiaceae)

Anatomical leaf characters could be used in the recognition of six species of Posoqueria studied, such as anticlinal wall of epidermal cells, wax deposition, trichomes and shape of the leaf margin.

Flower Extracts from Ornamental Plants as Sources of Sunscreen Ingredients: Determination by In Vitro Methods of Photoprotective Efficacy, Antigenotoxicity and Safety

Plants are sources of sunscreen ingredients that prevent cellular mutations involved in skin cancer and aging. This study investigated the sunscreen properties of the extracts from some ornamental

Low abundance of long-tongued pollinators leads to pollen limitation in four specialized hawkmoth-pollinated plants in the Atlantic Rain forest, Brazil

Long-tubed hawkmoth-pollinated species present some of the most remarkable examples of floral specialization depending exclusively on long-tongued hawkmoths for sexual reproduction. Nonetheless,

Reproductive outputs to floral trait variation in Nicotiana alata (Solanaceae) in Southern Brazil

Floral traits are useful for understanding how natural selection has acted upon the evolution of plants over short time spans and in restrictive ecological scenarios. Furthermore, the spatio-temporal

Pollen morphological support for the Catesbaeeae-Chiococceae-Exostema-complex (Rubiaceae)

Pollen and orbicule morphology proved to be a powerful tool to delimit the Catesbaeeae-Chiococceae-Exostema complex and the overall delimitation of the complex is corroborated with pollen data.

Phylogeny of the Gardenieae (Rubiaceae)

Abstract The phylogeny of Gardenieae (Rubiaceae) is evaluated using 70 morphological and anatomical characters and 81 terminal taxa. After successive reweighting of the characters and modified

Exotesta morphology of the Gardenieae — Gardeniinae (Rubiaceae)

It is concluded that data on exotesta morphology alone does not support any of the previously proposed informal groups, but may still be an important character to deduce phylogenetic relationships, primarily on a level just above the genus.

A phylogenetic study of the tribe Sipaneeae (Rubiaceae, Ixoroideae), using trnL–F and ITS sequence data

It is indicated that tribe Sipaneeae is monophyletic, and its placement within Ixoroideae is confirmed, indicating that the herbaceous habit evolved two times in the tribe.

Pollen morphology of the Gardenieae-Gardeniinae (Rubiaceae)

Pollen grains of 107 species of 61 genera of the Gardeniinae were investigated by scanning electron and light microscopy and found most genera are fairly stenopalynous, but in the neotropical genera Alibertia and Randia several different types of pollen are encountered.

Circumscription of the tribeCinchoneae (Rubiaceae)—a cladistic approach

It is concluded that the tribeCinchoneae, in order to be monophyletic, should be restricted to compriseCapirona, Cephalodendron, Cinchona, Cosmibuena, Dolicholobium, Ferdinandusa, Joosia, Ladenbergia, Macrocnemum, andRemijia.

A TRN LF CPDNA SEQUENCE STUDY OF THE CONDAMINEEAE-RONDELETIEAE-SIPANEEAE COMPLEX WITH IMPLICATIONS ON THE PHYLOGENY OF THE RUBIACEAE 1

DNA sequences from the chloroplast trnL-F region of 154 Rubiaceae and 11 outgroup taxa were analyzed cladistically. An emphasis was placed on the tribes Rondeletieae, Sipaneeae, and Condamineeae.

A trnL-F cpDNA sequence study of the Condamineeae-Rondeletieae-Sipaneeae complex with implications on the phylogeny of the Rubiaceae.

DNA sequences from the chloroplast trnL-F region of 154 Rubiaceae and 11 outgroup taxa were analyzed cladistically. An emphasis was placed on the tribes Rondeletieae, Sipaneeae, and Condamineeae.

Notes on the Rubiaceae of Surinam

In my revision of the Rubiaceae in Pulle’s Flora of Surinam two genera, viz. Pagamea and Perama, which are now usually included in this family, are relegated to an appendix. On account of its

Remarks on the position, the delimitation and the subdivision of the Rubiaceae

Some of the characters by the aid of which in the Rubiaceae very suitable keys to the genera have been constructed, but which when they were used for the elaboration of a classification, led to entirely unsatisfactory results are discussed.
