Anatomical features of species of Cyperaceae from northeastern Brazil

  title={Anatomical features of species of Cyperaceae from northeastern Brazil},
  author={Shirley Martins and Marccus V. S. Alves},
Seventy-three species from 17 genera of Cyperaceae were studied with the aim of identifying and confirming those species with Kranz anatomy. Among the species studied, 36 exhibited Kranz anatomy; 37 did not. Of the four types of Kranz anatomy recognized in Cyperaceae, three were encountered: the chlorocyperoid type in the genera Cyperus, Kyllinga, Lipocarpha, Pycreus, and Remirea; the fimbristyloid type in Abildgaardia, Bulbostylis, and Fimbristylis; and the rhynchosporoid type in Rhynchospora…

The present work contains anatomical descriptions of culms and leaves anatomy of three taxa of Cyprus spp.

Leaf anatomical characters in relation to the C3 and C4 photosynthetic pathway in Cyperus (Cyperaceae)

A combination of characters, such as the occurrence of Kranz tissue, maximum cell distant count, maximum lateral cell count, interveinal distance, and to some extent leaf and mesophyll thickness, provide a reliable basis for the assessment of the photosynthetic pathways of the investigated species as compared to the isolated characters used previously.

Evidence of genetic differentiation and karyotype evolution of the sedges Cyperus ligularis L. and C. odoratus L. (Cyperaceae)

Lower genetic variation in C. ligularis may be a result of the founder eff ect associated with seed dispersion and clonal reproduction, and field observations and analysis of reproductive biology should enrich the understanding of the genetic structure of the investigated populations and their role in successional processes.

Bundle sheath ontogeny in Kranz and non-Kranz species of Cyperaceae (Poales)

The ontogeny of the bundle sheaths of leaves and scapes of Cyperaceae species was studied to determine primary homologies and standardise the terminology used for its description.

Weeds of Pakistan: Cyperaceae.

The important weeds of Cyperaceae excluding the genus Carex infesting various crops number approximately 34. These include the genera Bolboschoenus, Bulbostylis, Cyperus, Eleocharis, Fimbristylis,

Silicified bulliform cells of Poaceae: morphological characteristics that distinguish subfamilies

Morphometric methods were great tools for delimiting morphotypes; with refined morphological classification the association between forms and habit/habitats was revealed and the knowledge provides new ways to interpret phytolith assemblage data.

Fitofisionomia das formações vegetais da Restinga da Área de Proteção Ambiental (APA) de Guaibim, Valença, Bahia, Brasil

The occurrence and distribution of the vegetation types of the Environmental Protection Area (APA) of Guaibim were assessed from field visits and satellite images. Were recognized eight vegetation

Inflorescence and floral characters indicating C 3 and C 4 photosynthesis in some species of the genus Cyperus L. (Cyperaceae)

Inflorescence and floral morphological characters in twelve species of Cyperus were investigated in order to check their usefulness in delimiting species into photosynthetic groups and revealed that compound umbellate inflorescence, digitately arranged spikelets and short spikelets not over 1cm long are  characters that separate C. difformis and C. haspan.

Plants used in basketry production during the Early Neolithic in the north-eastern Iberian Peninsula

Plant-based artefacts are rarely preserved in archaeological contexts in the Iberian Peninsula. Very few sites with specific conditions such as waterlogging, aridity or carbonization have preserved

The Fatty Acid Profile Analysis of Cyperus laxus Used for Phytoremediation of Soils from Aged Oil Spill-Impacted Sites Revealed That This Is a C18:3 Plant Species

It is demonstrated that weathered hydrocarbons may drastically affect the lipidic composition of C. laxus at the fatty acid level, suggesting that this species adjusts the cover lipid composition in its vegetative organs, mainly in roots, in response to the weathered Hydrocarbon presence and uptake during the phytoremediation process.



An investigation for the occurrence of C4 photosynthesis in the Cyperaceae from Australia

The anatomical observation revealed that the C4 species possessed any one of the three Kranz anatomical types found by previous investigators, and it was suggested that in the Cyperaceae the C 4 syndrome evolved independently within several taxa of the subfamily.

The occurrence of C4 species in the genusRhynchospora and its significance in kranz anatomy of the cyperaceae

Rhynchospora rubra was found to have a low CO2 compensation point, high δ13C value, Kranz leaf anatomy, starch present in the bundle sheath cells and narrow interveinal distance, suggesting that it is a C4 plant.

The systematic anatomy of south Indian Cyperaceae: Cyperus L. subgen. Kyllinga (Rottb.) Suringar

The present work contains anatomical descriptions of seven taxa belonging to Cyperus subgen.Kyllinga. There are 11 characters common to all the specieS. However, in the light of the observed

Anatomia do escapo e rizoma de espécies brasileiras de Bulbostylis Kunth (Cyperaceae)

The characters found to be of taxonomic value in key species of Bulbostylis Kunth are: the shape of the scape in transverse section, the presence of ribs and furrows, the aspect of the epidermal cells and stomata, theshape of the cortical sclerenchymatous strands, the number of vascular unit, a fistulose medulla, and the occurrence of radiate parenchyma.

Photosynthesis pathways, ecological characteristics, and the geographical distribution of the Cyperaceae in Japan

The nature of the photosynthetic pathways of Cyperaceae found in Japan were investigated on the basis of Kranz anatomy, the CO2 compensation concentration and previously reported data to determine the climatic factors that influence the relative floristic abundance of C3 and C4 members of the Cyper Families in Japan.

Bienertia sinuspersici (Chenopodiaceae): A New Species from Southwest Asia and Discovery of a Third Terrestrial C4 Plant Without Kranz Anatomy

Its wide distribution indicates that its novel C4 photosynthesis may confer advantages for CO2 fixation in these habitats not found in C4 species having conventional Kranz anatomy, and supports the conclusion that this widely distributed, novel plant is an overlooked new species.

It seems that inRhynchospora the C4 syndrome evolved relatively recently, and arose in at least two separate phylogenetic trends in the tropics and the subtropics, more probably in the Neotropics.

Distribution of South African C3 and C4 species of Cyperaceae in relation to climate and phylogeny

The analysis of the current geographical distribution of C 4 Cyperaceae in southern Africa in a phylogenetic context suggests that the ecological advantages conferred by the C 4 pathway differ amongst the different plant groups.
