In phylogenetic studies across angiosperms, at various taxonomic levels, polytomies have persisted despite efforts to resolve them by increasing sampling of taxa and loci. The large amount genomic data now available statistical tools analyze provide unprecedented power for inference. Targeted sequencing has emerged as a strong tool estimating species trees in the face rapid radiations, lineage sorting introgression. Evolutionary relationships Cyperaceae been studied mostly using Sanger until...
Abstract Cyperaceae (sedges) are the third largest monocot family and of considerable economic ecological importance. Sedges represent an ideal model to study evolutionary biology due their species richness, global distribution, large discrepancies in lineage diversity, broad range preferences, adaptations including multiple origins C 4 photosynthesis holocentric chromosomes. Goetghebeur′s seminal work on published 1998 provided most recent complete classification at tribal generic level,...
Abstract The Checklist of the Vascular Plants Republic Guinea (CVPRG) is a specimen-based, expert-validated knowledge product, which provides concise synthesis and overview current on 3901 vascular plant species documented from (Conakry), West Africa, including their accepted names synonyms, as well distribution status within (indigenous or introduced, endemic not). CVPRG generated automatically Collections Database Names Backbone Database, both developed maintained at Royal Botanic Gardens,...
Summary Grasses (Poaceae) comprise around 11,800 species and are central for human livelihoods terrestrial ecosystems. Knowing their relationships evolutionary history is key to comparative research crop breeding. Advances in genome-scale sequencing allow increased breadth depth of phylogenomic analyses, making it possible infer a new reference tree the family. We inferred comprehensive grasses by combining published sequences 331 nuclear genes from genome, transcriptome, target enrichment...
A taxonomic revision of the genus Scleria ( Cyperoideae , Cyperaceae ) in Madagascar is presented. Herbarium specimens have been examined and 422 identified to species level. Our results recognise 25 from Madagascar, plus an additional heterotypic variety. Eight are endemic two near endemic, eight taxa also found on mainland Africa, widespread tropical taxa. achtenii reported for first time, S. rosea accepted at level instead being considered as a synonym trialata . Distribution maps,...
Summary Ctenium bennae Xanthos is described and illustrated as the only rheophytic species in genus. The new known from a single waterfall on Benna Plateau, at border between Forecariah Kindia Prefectures Guinea Conakry. here assessed Near Threatened according to categories criteria of IUCN.
Background and aims – The Cyperus margaritaceus-niveus complex is a group of ten tropical species from sub-Saharan Africa Madagascar: C. karlschumannii , kibweanus ledermannii margaritaceus niveus nduru obtusiflorus somaliensis sphaerocephalus tisserantii . They are characterised by capitate head white-yellow spikelets modified culm bases recent molecular analysis puts them in distinct clade. lacks modern taxonomic revision, the taxa described Flora treatments past 50 years differ...
A recent molecular phylogenetic study revealed four distinct evolutionary lineages in the genus Costularia s.l. (Schoeneae, Cyperaceae, Poales). Two are part of Oreobolus clade tribe Schoeneae: first being a much-reduced s.s., and second lineage endemic to New Caledonia for which new Chamaedendron was erected. The other two were shown be Tricostularia Schoeneae. Based on morphological data, is here redelimited represent monophyletic entity including 15 species, restricted distribution...
Micro-morphological examination of nutlets show that Schoenoplectiella lateriflora subsp. laevinux (Cyperaceae), recorded from Tanzania, is synonymous with erecta erecta, thus extending the range this species. Examination herbarium specimens also shows species to be present in Zambia.
Summary The name Cyperus atronervatus subsp. angustifolius was not validly published due to the omission of a Latin diagnosis. is here.
The genus Hypolytrum Rich. ex Pers. (Cyperaceae) is comprised of ca. 50 species (Nelmes 1955) distributed throughout the tropics and subtropics. most easily confused with Mapania Aubl., as both genera can have large basal strap-like leaves a globose capitate inflorescence. usually distinguished by having 2 floral bracts within spicoid compared 4–6 in (Simpson 1992). In these are initially fused together but then rupture to expose maturing achene 1955).
Sinobambusa tootsik (Makino) Makino ex Nakai, the Chinese Temple Bamboo, is described and illustrated from material flowering at Kew. Its distribution given suggestions for its cultivation are provided.
