A new species of Gymnanthemum (Compositae, Vernonieae) from South Africa is described. It can be distinguished from other species in the genus by the five-flowered capitula and widely obtuse leaf blades.

An updated subtribal classification of the Compositae–Anthemideae is presented based on gene- and species-tree reconstructions considering sequence variation from plastid (cpDNA ndhF, trnL-trnF) nuclear genome (nrDNA ITS1-5.8S-ITS2, ETS; nDNA dual specificity phosphatase DSP, plus-3 domain-containing protein vernalization independence 5 complex VIP5, major facilitator superfamily Nitrate Transp...

BACKGROUND The Australian cushion bush (Leucophyta brownii) of the Compositae family of plants has become a popular pot and container plant. The plant produces the sesquiterpene lactone allergen calocephalin. OBJECTIVES To assess the sensitizing potential of sesquiterpene lactones from cushion bush. PATIENTS/MATERIALS/METHODS Eleven Compositae-sensitive patients were patch tested with seven...

Echinops wakhanicus Rech.f. (Compositae: Cardueae: Echinopsinae) is described and illustrated, its taxonomic position discussed. Field observations seed collection of the species are mentioned. The genus discussed, comments made on infrageneric classification, placement E. in sect. Oligolepis. terminology used describing flowering structure discussed; term synflorescence preferred. Tribal subtr...

Lettuce (Lactuca sativa) is a major crop and a member of the large, highly successful Compositae family of flowering plants. Here we present a reference assembly for the species and family. This was generated using whole-genome shotgun Illumina reads plus in vitro proximity ligation data to create large superscaffolds; it was validated genetically and superscaffolds were oriented in genetic bin...

Five species of eriophyoid mites were identified during surveys of mite fauna associated with plant species of the family Compositae from Southwest of East Azerbaijan province during 2010 and 2011. Two of them, Aceria virgatae n. sp. from Centaurea virgata Lam. and Aceria xeranthenzis n. sp. from Xeranthemumn squarrosum Boiss., were found to be new to science. No damage symptoms were observed o...

The family Asteraceae or compositae known as the ester, daisy or sunflower family is the largest family of flowering plants. Artemisia is a large diverse genus of plants with between 100 to 150 species belonging to the family asteraceae (compositae). It comprises hardy herbs and shrubs known for their volatile oils. They grow in temperate climate of the northern hemisphere and southern hemisphe...
