A taxonomic backbone for the global synthesis of species diversity in the angiosperm order Caryophyllales
The Caryophyllales constitute a major lineage of flowering plants with approximately 12500 species in 39 families. A taxonomic backbone at the genus level is provided that reflects the current state of knowledge and accepts 749 genera for the order. A detailed review of the literature of the past two decades shows that enormous progress has been made in understanding overall phylogenetic relationships in Caryophyllales. The process of re-circumscribing families in order to be monophyletic appears to be largely complete and has led to the recognition of eight new families (Anacampserotaceae, Kewaceae, Limeaceae, Lophiocarpaceae, Macarthuriaceae, Microteaceae, Montiaceae and Talinaceae), while the phylogenetic evaluation of generic concepts is still well underway. As a result of this, the number of genera has increased by more than ten percent in comparison to the last complete treatments in the Families and genera of vascular plants” series. A checklist with all currently accepted genus names in Caryophyllales, as well as nomenclatural references, type names and synonymy is presented. Notes indicate how extensively the respective genera have been studied in a phylogenetic context. The most diverse families at the generic level are Cactaceae and Aizoaceae, but 28 families comprise only one to six genera. This synopsis represents a first step towards the aim of creating a global synthesis of the species diversity in the angiosperm order Caryophyllales integrating the work of numerous specialists around the world
Fasciación en un individuo de Atriplex elegans (Moq.) D. Dietr. (Chenopodiaceae)
A teratological phenomenon found in a plant of Atriplex elegans subsp. thornberi (M. E. Jones) W. L. Wagner, from a wild population in Sonora, México, is described. Its flattened and expanded stem from the base to the terminal portion, its terminal bifurcation and coiled appearance are indicative of a fasciation. The phenomenon affects also the inflorescence.Se describe un caso teratológico en un individuo de Atriplex elegans subsp. thornberi (M. E. Jones) W. L. Wagner, proveniente de una población ruderal de Sonora, México. Por las características de la anomalía, que consiste en el aplanamiento y ensanchamiento de un tallo, desde la base hasta la porción terminal que se bifurca y enrolla, se puede considerar que se trata de un fenómeno de fasciación que afecta también a las inflorescencias
La Lista de nombres vulgares y botánicos de árboles y arbustos propicios para repoblar los bosques de la República de Fernando Altamirano y José Ramírez a más de 110 años de su publicación The List of common and botanical names of trees and shrubs suitable for restoration of the woods of the Republic by Fernando Altamirano and José Ramírez, more than 110 years after its publication
Dado el valor histórico y práctico de la lista de árboles y arbustos para repoblar los bosques de la República Mexicana que Altamirano y Ramírez publicaron hace 111 años y de la inaccesibilidad para consultarla, se elaboró una lista con los nombres científicos corregidos y/o los sinónimos actualizados, en su caso, para facilitar la consulta. Se proponen las posibles especies a las que Altamirano y Ramírez se refirieron, y para las que sólo indicaron nombre vulgar y género. Se anota si las especies son nativas o introducidas, su uso en el presente y los métodos de propagación. Se analiza y discute la lista a la luz de los enfoques actuales de restauración. El documento original consta de 281 nombres vulgares que representan 259 especies de 72 familias; 231 especies son angiospermas y 28 gimnospermas. La mayoría de los géneros tienen una sola especie y tan solo nueve, más de cuatro: Pinus con 19, Quercus con 11, Cordia y Tabebuia con cinco, Annona, Bursera, Caesalpinia, Juniperus y Yucca con cuatro. Se reproduce la carátula y la última página de la edición de l894.<br>Because of the importance of the list of plant species for repopulating the forests of the Mexican Republic, first published by Altamirano and Ramírez 111 years ago, and the difficulty to access it, a list is presented considering current trends in ecological restoration, and corrected scientific names were added to facilitate its use. To improve the utility of the list some information such like if the species are native or introduced, their uses and propagation methods is provided. The authors provide 281 common names that represent 259 species of 72 families of which 231 species are angiosperms and 28 gymnosperms. Most of the genera are represented by one species and only nine genera are represented by four or more species: Pinus (19 species), Quercus (11 species), Cordia and Tabebuia (5 species each) and Annona, Bursera, Caesalpinia, Juniperus and Yucca (4 species each).

Enigmatic floral structures in Alternanthera, Iresine, and Tidestromia (Gomphrenoideae, Amaranthaceae). A developmental homology assessment
Background and aims – Amaranthaceae comprise the former Chenopodiaceae, Beta, and core-Amaranthaceae. Particularly in the Gomphrenoid clade, most species have flowers with an 'androecial tube'. On its rim and alternating with the stamens, so-called (pseudo-)staminodia occur. However, neither their origin nor function have been clarified. We aimed to determine the nature of both the 'androecial tube' and pseudostaminodia in species of three genera: Iresine, Alternanthera and Tidestromia . In addition, we also aimed to document the development of the gynoecium. Methods – Scanning electron microscopic (SEM) and light microscopic (LM) observations of the floral development. Key results – Five individual sepal primordia appear in quincuncial order, followed by the appearance of five individual stamen primordia opposite them. At semi-maturity, the stamens are raised by the formation of a tube below them, with at its inside surface a glandular zone. Alternating with the stamens, appendages develop from individual primordia on the rim of the androecial tube. In bisexual/female flowers, from a primary gynoecium primordium, secondarily, an annular gynoecium wall primordium is formed, surrounding a central zone from which a single ovule develops. At maturity, the gynoecium stands on a gynophore. In Alternanthera microcephala, the gynophore may become large, sometimes developing appendages. Conclusions – Our hypothesis that the androecial tube develops from an underlying annular intercalary meristem is supported by the absence of an annular androecium primordium and the late development of the androecial tube. The 'pseudostaminodes' are appendages of the androecial tube. Their often conspicuous appearance and the glandular inside surface of the androecial tube suggest an animal(insect)-based pollination syndrome. We consider the androecial tube, the staminal ring in flowers of Beta vulgaris and the 'fused filaments' in some Chenopodioideae as morphological homologues. We suggest that the development of the gynoecium wall might be decoupled from the development of the ovule
