Taxonomic revision of the threatened African genus Pseudohydrosme Engl. (Araceae), with P. ebo, a new, critically endangered species from Ebo, Cameroon
This is the first revision in more than 100 years of the African genus Pseudohydrosme, formerly considered endemic to Gabon. Closely related to Anchomanes, Pseudohydrosme is distinct from Anchomanes because of its 2-3-locular ovary (vs. unilocular), peduncle concealed by cataphylls at anthesis and far shorter than the spathe (vs. exposed,...Cheek, Martin ; Tchiengué, Barthélemy ; van der Burgt, Xander

Delimiting the genera of the Ficinia Clade (Cypereae, Cyperaceae) based on molecular phylogenetic data
Generic delimitations in the Ficinia Clade of tribe Cypereae are revisited. In particular, we aim to establish the placement of annual species currently included in Isolepis of which the phylogenetic position is uncertain. Phylogenetic inference is based on two nuclear markers (ETS, ITS) and five plastid markers (the genes matK,...Muasya, A. Muthama ; Larridon, Isabel

A taxonomic revision of Iris subser. Sibiricae is provided based on morphological and molecular analyses and the study of protologues and original material. Two to three species have been recognized in this subseries by botanists. To address the question of species delimitations and relationships within this group, we analyzed four...Boltenkov, Eugeny ; Artyukova, Elena ; Kozyrenko, Marina ; Erst, Andrey ; Trias-Blasi, Anna

Native trees of Mexico: diversity, distribution, uses and conservation
Background Mexico is one of the most floristically rich countries in the world. Despite significant contributions made on the understanding of its unique flora, the knowledge on its diversity, geographic distribution and human uses, is still largely fragmented. Unfortunately, deforestation is heavily impacting this country and native tree species...Tellez, Oswaldo ; Mattana, Efisio ; Diazgranados, Mauricio ; Kühn, Nicola ; Castillo-Lorenzo, Elena …

Genome size variation at constant chromosome number is not correlated with repetitive DNA dynamism in Anacyclus (Asteraceae)
Abstract Background and Aims Changes in the amount of repetitive DNA (dispersed and tandem repeats) are considered the main contributors to genome size variation across plant species in the absence of polyploidy. However, the study of repeatome dynamism in groups showing contrasting genomic features and complex evolutionary histories is needed...Vitales, Daniel ; Álvarez, Inés ; Garcia, Sònia ; Hidalgo, Oriane ; Nieto Feliner, Gonzalo …

Convergent evolution in calyptrate flowers of Syzygieae (Myrtaceae)
Abstract Shedding a fused perianth as a calyptra at anthesis is a trait that has evolved independently multiple times in angiosperm evolutionary history. However, calyptras do not correspond to homologous structures in all cases. Here, we describe calyptra development in the evolutionary context of Myrtaceae tribe Syzygieae. We use scanning...Vasconcelos, Thais N C ; Lucas, Eve J ; Conejero, Maria ; Giaretta, Augusto ; Prenner, Gerhard

The endemic ‘sugar canes’ of Madagascar (Poaceae, Saccharinae: Lasiorhachis) are close relatives of sorghum
Crop wild relatives are important but often poorly known. This is the case for subtribe Saccharinae (Poaceae: Andropogoneae), which includes sugarcane (Saccharum) and sorghum (Sorghum). We present a phylogenetic and taxonomic account of the Malagasy endemic genus Lasiorhachis, previously included in Saccharum.

Colourful cones: how did flower colour first evolve?
Angiosperms that are biotically pollinated typically produce flowers with bright and contrasting colours that help to attract pollinators and hence contribute to the reproductive success of the species. This colourful array contrasts with the much less multicoloured reproductive structures of the four living gymnosperm lineages, which are predominantly wind pollinated,...Rudall, Paula J

A novel phylogenetic infrageneric classification of Baccharis (Asteraceae: Astereae), a highly diversified American genus
