Das hier vorgestellte Klassifikationssystem basiert auf den aktuellen molekularphylogenetischen Untersuchungen. Die für die einzelnen Taxa wichtigen Merkmale werden vorgestellt und ihre Bedeutung für die Systematik erörtert. In den einzelnen Gruppen werden wichtige einheimische Ordnungen und Familien präsentiert sowie relevante Gattungen und Arten besprochen. Die 600 im Buch aufgenommenen Arten entsprechen der Liste des Zertifikates 600 der Schweizerischen Botanischen Gesellschaft; damit sind implizit auch die Arten des Zertifikats 200 und des Zertifikats 400 enthalten. Das Buch deckt auch den grössten Teil des für das Zertifikat 600 verlangten allgemeinen Wissens in Feldbotanik ab. Neben systematischen, morphologischen und ökologischen werden auch angewandte Aspekte berücksichtigt (z.B. nahrungsliefernde Pflanzen, Medizinalpflanzen). Da das Schwergewicht auf der einheimischen Flora liegt, we...

A combined analysis of ndhF, matK, and nadl sequence data from the chloroplast and the mitochondrial genomes indicates that the tribe Anacampseroteae is the sister group of the family Cactaceae. This clade, together with Portulaca, is well characterized by the presence of axillary hairs or scales. Relationships within Anacampseroteae are characterized by a grade of five species of Grahamia s.l. from North and South America, and Grahamia australiana is found to be sister to the genera Anacampseros and Avonia. A comparison of vegetative characteristics indicates an evolutionary transition from woody subshrubs to dwarf perennial and highly succulent herbs during the diversification of Anacampseroteae. Available evidence from the present investigation as well as from pre...

Based on historical manuscripts and books by Johannes Kentmann (1518-1574) and Conrad Gessner (1516-1565), the early introduction history of the genus Opuntia (prickly pear; Cactaceae) into the botanical literature is reconstructed. The first author to use the name Opuntia in print was Pietro Andrea Mattioli in 1554, but the first occurrence of the name is in the illustrated manuscript (Codex Kentmanus) of Johannes Kentmann compiled in 1549, where the first use of the name is attri buted to Luigi Anguillara, at that time the curator of the Botanical Garden in Padua. Apart from the Codex Kentmanus, a second manuscript of Johannes Kentmann, the Kreutterbuch from 1563, has also survived to the present day. The illustrations of succulent plants from these two sources are listed in tabular form, and those present in both manuscripts are reproduced, together with the copies that were made by Conrad Gessner in 1554/55.

Examination of physical specimens remains a key task, but searching for specimen data, literature, and name information is now mostly done online. In the past, these research steps involved many physical visits to collections and libraries. Although these infrastructures were and are still freely accessible and supportive for research carried out by individuals, the amount of characters, specimens, and the complexity of current analytical approaches limit what can be achieved by individual workers. Monographing is challenged because: larger genera remain unstudied and become fragmented in regional treatments; long-term availability of detailed (unpublished) primary research data is often not addressed; cross-disciplinary interoperability and open data principles are needed; and highly spe...

Disintegrating Portulacaceae: A new familial classification of the suborder Portulacineae (Caryophyllales) based on molecular and morphological data

However, phylogenetic analyses based on molecular sequence data indicate that the traditional family Portulacaceae is paraphyletic and consists of three distinct lineages that also include Cactaceae, Didiereaceae, and Hectorellaceae. We use sequence data from the chloroplast genes matK and ndhF representing 64 species of Portulacineae and outgroups to reconstruct their phylogenetic relationships with Bayesian and maximum parsimony inference methods. Evidence from these molecular phylogenetic analyses as well as from comparative morphological investigations allow us to propose a revised familial classification of the suborder Portulacineae. We recognize eight monophyletic families:

Cactaceae at Caryophyllales.org – a dynamic online species-level taxonomic backbone for the family

The data will form a contribution of the Caryophyllales Network for the World Flora Online and serve as the base for further integration of research results from the systematic research community. The final aim is to treat all effectively published scientific names in the family. The checklist includes 150 accepted genera, 1851 accepted species, 91 hybrids, 746 infraspecific taxa (458 heterotypic, 288 with autonyms), 17,932 synonyms of accepted taxa, 16 definitely excluded names, 389 names of uncertain application, 672 unresolved names and 454 names belonging to (probably artificial) named hybrids, totalling 22,275 names. The process of compiling this database is described and further editorial rules for the compilation of the taxonomic backbone for the Caryophyllales Network are proposed. A checklist depicting the current state of the taxonomic backbone is provided as. All results are also available online on the website of the Caryophyllales Network and will be constantly updated and expanded in the future.
