TL;DR: A cladistic analysis of 45 genera ofCardueae for 75 characters is presented, taking into account characters of bracts, corolla, stamens, styles and cypselas, finding the traditional Carlininae is a paraphyletic group.
Abstract: A cladistic analysis of 45 genera ofCardueae for 75 characters is presented, taking into account characters of bracts, corolla, stamens, styles and cypselas. Forty-six binary characters completeBremer's (1994) work. Some of the characters considered byBremer are criticised. The traditionalCarlininae is a paraphyletic group, the ten genera studied sharing no common derived character. A new classification of theCardueae is proposed and the distribution of the tribe is presented. Several new combinations are proposed. The nomenclature ofCentaurea is discussed and the status of the genusSerratula is analysed.

TL;DR: Cladistic analyses of Anacardiaceae using non-sequence data, sequence data and combined datasets supported the recognition of a second subfamily: Spondiadioideae Kunth emend and suggested that Buchanania lies outside both subfamily groups.
Abstract: Cladistic analyses were undertaken of Anacardiaceae using non-sequence data (30 genera and 81 characters from morphology, anatomy, palynology and chemotaxonomy), sequence data (26 genera – rbcL) and a combined dataset of 16 genera. All analyses supported a group of genera which can be recognised at the subfamily level: Anacardioideae. Sequence data and combined datasets supported the recognition of a second subfamily: Spondiadioideae Kunth emend. Wannan. Both datasets also suggested that Buchanania lies outside both subfamily groups.

TL;DR: Serial sections of young and old woody stems of Atriplex halimus L. (Chenopodiaceae) were studied with the light microscope and analyzed cinematographically to search for possible connections between the cambia occurring in the primary vascular bundles and the successive c Cambia.
Abstract: Serial sections of young and old woody stems of Atriplex halimus L. (Chenopodiaceae) were studied with the light microscope and analyzed cinematographically to search for possible connections between the cambia occurring in the primary vascular bundles and the successive cambia. The first extrafascicular cambia initiated from cambial bands which develop continuous with the still active intrafascicular cambia of the primary vascular bundles. The additional successive cambia also appear to start developing continuous with preceding still active cambia. The primary vascular bundles and the vascular strands of the secondary increments are all interconnected.

TL;DR: Evidence from leaf epidermis strongly suggests the separation of the Chloranthaceae genus into two groups according to the characteristics of androecial organs.

TL;DR: It is demonstrated that n-alkyl lipid distributions from fossil leaves have chemotaxonomic utility, with potential for comparisons with modern taxa.
