Local perceptions of the benefits versus negative impacts of weedy grasses in central Madagascar, with a focus on the genus Digitaria.
Les plantes et les pratiques agricoles sont essentielles aux systèmes alimentaires et au bien‐être humain. Une approche de recherche ethnobotanique a été présentée pour mieux comprendre la relation entre les plantes et les activités humaines à Madagascar, où l'agriculture constitue la base de l'économie locale. Cette recherche examine les... -

Implications of a local flora survey for pre‐human grass flora in north‐western Madagascar.
On apprend aux enfants de Madagascar que leurs ancêtres ont détruit la vaste forêt ancienne donnant naissance aux prairies modernes, un mythe trompeur qui continue à saper la relation des gens avec la nature. Remplacer ce mythe par un récit plus nuancé et précis sur les écosystèmes herbeux est... -

Evolutionary history, traits, and weediness in Digitaria (Poaceae: Panicoideae).
Digitaria is a large pantropical genus, which includes a number of economically problematic agricultural weeds. Difficulties in species identification and the circumscription of the genus have previously hindered progress in understanding its evolution and developing a stable classification. We investigate the evolutionary history of Digitaria by combining two approaches: (i)... -

Evolutionary diversity of the endemic genera of the vascular flora of Chile and its implications for conservation.
As a direct consequence of global change, both natural and human-induced, a high percentage of biodiversity is now under threat worldwide. This has urged conservation planners to formulate and/or improve existing strategies to preserve species and their ecosystems. In this context, the present study focuses on two strategies using phylogeny-based... -

A Taxonomic Revision of Styppeiochloa (Arundinoideae: Poaceae) in Madagascar.
The grass genus Styppeiochloa De Winter (Arundinoideae: Poaceae) as it occurs in Madagascar is reviewed, two new species are described, and two subspecific taxa are elevated to species status. These new species, as well as the additional collections made since the latest treatment of the genus for Madagascar in 1954,... -

Evolutionary history of the grass gynoecium.
The grass family (Poaceae) includes cereal crops that provide a key food source for the human population. The food industry uses the starch deposited in the cereal grain, which develops directly from the gynoecium. Morphological interpretation of the grass gynoecium remains controversial. We re-examine earlier hypotheses and studies of morphology... -

The genus Tristachya (Poaceae: Panicoideae) in Madagascar.
We present a revision of the three species of in Madagascar. The tussock-forming is a rare endemic of the quartz outcrops in the Itremo Protected Area. The rhizomatous and are common components of the sandstone outcrop vegetation in the Isalo National Park. A new combination is made. Descriptions, conservation assessments,...Vorontsova, Maria S. ; Rakotomalala, Nantenaina H.

Inequality in plant diversity knowledge and unrecorded plant extinctions: An example from the grasses of Madagascar
Societal impact statement Plants are essential for all life, providing the infrastructure and energy for our ecosystems. A recent report indicates that more than 500 plant species are already presumed extinct and many more could have been lost without anyone being aware, especially in species‐rich areas with high levels of... -

Historical legacies and ecological determinants of grass naturalizations worldwide
The global distribution of exotic species is the result of abiotic, biotic and dispersal filtering processes that shape the movement and success of species outside their native range. In this study we aim to understand how these filtering processes drive the fluxes of grass species among regions, the factors that... -

The discovery, typification and rediscovery of wild emmer wheat, Triticum turgidum subsp. dicoccoides (Poaceae)
Wild emmer, Triticum turgidum subsp. dicoccoides, is an annual tetraploid wheat characterized by a brittle spike axis that spontaneously disintegrates at maturity. It occurs widely in the so-called Fertile Crescent of the Near East and is of great importance for understanding wheat evolution and for breeding modern wheat cultivars tolerant...Lack, Hans Walter ; Van Slageren, Michiel

Madagascar Grass Atlas
Madagascar has a unique heritage in terms of biodiversity. Its separation from Africa set the backdrop for the unique evolution of its flora and fauna. Its isolated island nature gave rise to high endemism and explosive speciation. Of its estimated 12,000 vascular plant species, 83% are unique to Madagascar (Madagascar...
