Background – Vegetative and fruit characters of the Amazonian genus Dialypetalanthus point to a position in Rubiaceae. However, its floral morphology is so deviant that the genus was often placed in a family of its own. Even relationships outside G

Background and aims – Rubieae is a tribe in the subfamily Rubioideae characterised by herbaceous plants with verticillate leaves and flowers with a rudimentary or absent calyx and a short, cup-shaped corolla. This is in contrast to the flowers of m

Background – Phialiphora (Spermacoceae, Rubiaceae) is a herbaceous genus restricted to unconsolidated white sands in open spaces in dry forests in northwestern Madagascar. The genus is characterized by the semi-succulent nature of its leaves and st

Systematic Biology
Understanding the evolution of biodiversity on Earth is a central aim in biology. Currently, various disciplines of science contribute to unravel evolution at all levels of life, from individual organisms to species and higher ranks, using different

Background and aims – In Rubiaceae, most flowers have a tubular corolla. Earlier studies showed that a tubular corolla may develop from an annular primordium or result from postgenital fusion of petals. Often stamen-corolla tubes are formed, concur

Background and aims – Amaranthaceae comprise the former Chenopodiaceae, Beta, and core-Amaranthaceae. Particularly in the Gomphrenoid clade, most species have flowers with an 'androecial tube'. On its rim and alternating with the stamens, so-called

Background and aims – Ontogenetic studies provide valuable morphological characters to aid interpretation of evolutionary scenarios. But they are rare within the Rubiaceae and the variation in floral ontogenetic patterns in the different Rubiaceae
