Polyploidy does not control all: Lineage‐specific average chromosome length constrains genome size evolution in ferns
Recent studies investigating the evolution of genome size diversity in ferns have shown that they have a distinctive genome profile compared with other land plants. Ferns are typically characterized by possessing medium‐sized genomes, although a few lineages have evolved very large genomes. Ferns are different from other vascular plant lineages...Liu, Hong‐Mei ; Ekrt, Libor ; Koutecky, Petr ; Pellicer, Jaume ; Hidalgo, Oriane …

A synopsis of Polysphaeria (Rubiaceae) in Mozambique, including two new species
The genus Polysphaeria is investigated in Mozambique based on detailed morphological studies of herbarium specimens, resulting in the recognition of two new species. The first, P. ribauensis, is based on Kraussia sp. A of Flora Zambesiaca and is endemic to the Ribáuè Mountains of Nampula Province. The second, P. harrisii,...Darbyshire, Iain ; Langa, Clayton ; Romeiras, Maria

A revision of the Crepidorhopalon whytei complex (Linderniaceae) in eastern Africa
The Crepidorhopalon whytei (Linderniaceae) species complex is revised using morphological analyses. Based primarily on variations in indumentum, floral morphology, corolla colour and seed morphology, four species are formally recognised within this group in eastern Africa. Crepidorhopalon whytei s.str. is widespread in the highlands of eastern Africa, extending from South Sudan...Darbyshire, Iain ; Wursten, B. ; Luke, Q. ; Fischer, E.

Information gaps in indigenous and local knowledge for science-policy assessments
The need to understand nature’s contributions to people and across a broad spectrum of cultures and ecosystems is increasingly advocated in science assessments and policy decision-making for sustainability. However, for services such as food and medicine, gaps in existing studies on indigenous and local knowledge may preclude inclusive assessments. Here,...Cámara-Leret, Rodrigo ; Dennehy, Zoe

A Target Capture-Based Method to Estimate Ploidy From Herbarium Specimens
Whole genome duplication (WGD) events are common in many plant lineages, but the ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most species. Standard methods for ploidy determination are chromosome counting and flow cytometry approaches. While flow cytometry approaches typically use fresh tissue, an increasing number...Viruel, Juan ; Conejero, María ; Hidalgo, Oriane ; Pokorny, Lisa ; Powell, Robyn …
