The use of molecular data in phylogenetic reconstruction during more than three decades has greatly improved our understanding of the macroevolutionary history of the coffee family (Rubiaceae) and has provided a solid basis for improvement of its classification. Based on the results of 130 studies, among them most recent phylogenomic works, we present a consensus phylogeny and a robust classification of Rubiaceae that shed light on the evolutionary success of this highly diverse angiosperm family and can serve as a framework for ecological and evolutionary studies. There are more than 14,000 species and about 580 accepted genera of Rubiaceae that are assigned to 71 tribes, of which 68 are classified in two subfamilies (Dialypetalanthoideae with 38 tribes and Rubioideae with 30 tribes). Three tribes (Acranthereae, Coptosapelteae, Luculieae) remain unclassified as to subfamily. Sixty‐three of these 71 tribes are assigned to nine informal alliances (four in Rubioideae and five in Dialypetalanthoideae). These tribes are listed in alphabetical order within their respective alliances. Five tribes, one (Coussareeae) in Rubioideae and four (Airospermeae, Jackieae, Retiniphylleae, Steenisieae) in Dialypetalanthoideae, are excluded from these alliances due to unclear or conflicting phylogenetic positions. Thirty‐six tribes retain their tribal status but receive new generic limits to remedy their previous para‐ or polyphyletic nature. Twenty‐nine tribes not implemented in previous classifications have been added, of which three (Chioneae, Glionnetieae, Temnopterygeae) are newly described here. Basic information on phylogenies, distributions, former classifications, and useful references to previous works are provided for all accepted tribes, and future perspectives are discussed.

The species-rich genus Impatiens (Balsaminaceae) is represented in Madagascar by no less than 260 species. We conducted molecular phylogenetic analyses of the Malagasy Impatiens based on nuclear and plastid data and 52 accessions (representing 33 species) to: 1) reassess the monophyly of the Malagasy Impatiens; 2) assess the monophyly of the sections Preimpatiens (Humblotianae and Vulgare groups) with spurs and Trimorphopetalum without spurs as delimited by Perrier de la Bâthie, as well as that of the subgenera Impatiens and Trimorphopetalum as defined by Fischer and Rahelivololona; 3) infer the current status of some morphologically variable species; and 4) test whether the species of Impatiens from the Marojejy National Park form a monophyletic group. The Malagasy Impatiens are further confirmed to be paraphyletic with respect of the Comorian I.auricoma. The present sectional and subgeneric classifications of the Malagasy Impatiens are partly supported, with strong support for the monophyly of the sect. or subgen. Trimorphopetalum. Section Preimpatiens was not supported as monophyletic and neither the Humblotianae group nor the Vulgare group is monophyletic. Impatienselatostemmoides, I. “hammarbyoides”, I.inaperta, I.lyallii and I.manaharensis are either para- or polyphyletic and may represent morpho-species. The Impatiens species from the Marojejy National Park do not form a monophyletic group and therefore are suggested to be derived from numerous independent colonisation events from all over Madagascar followed by subsequent diversifications.
