Two new combinations inAdenostyles (Asteraceae, Senecioneae), a conspectus of the genus and key to its species and subspecies
2012
Abstract Dillenberger M. S. & Kadereit J. W.: Two new combinations in Adenostyles (Asteraceae, Senecioneae), a conspectus of the genus and key to its species and subspecies. — Willdenowia 42: 57-61. June 2012. — Online ISSN 1868-6397; © 2012 BGBM Berlin-Dahlem. Stable URL: http://dx.doi.org/10.3372/wi.42.42105 Based on a molecular phylogeny (using ITS, ETS and the rpl32-trnL, psbA-trnH and ndhF-rpl32 plastid spacer sequences) of all species and subspecies of the European genus Adenostyles currently recognised, and supported by the morphology of the leaf margin, we transfer two subspecies of A. alliariae to A. alpina and provide the new combinations A. alpina subsp. macrocephala and A. alpin…
Taxonomic clarification in W-Mediterranean Androcymbium (Colchicaceae): A. wyssianum sunk in the synonymy of A.gramineum and A.europaeum restored
2010
Abstract Hoyo A. del & Pedrola-Monfort J.: Taxonomic clarification in W Mediterranean Androcymbium (Colchicaceae): A. wyssianum sunk in the synonymy of A. gramineum and A. europaeum restored. — Willdenowia 40: 47–53. — Online ISSN 1868-6397. — © 2010 BGBM Berlin-Dahlem. doi:10.3372/wi.40.40103 (available via http://dx.doi.org/) Capsule dehiscence has been used as a diagnostic character for W Mediterranean species of Androcymbium. Depending on the state of capsule maturity, the character, however, can be ambiguous in herbarium material. Based on morphological, phenological and cpDNA characters it is shown that misinterpretation of the capsule as indehiscent in the type material of A. gramine…

2013
Abstract Mering S. von: Tetroncium and its only species, T. magellanicum (Juncaginaceae): distribution, ecology and lectotypification. — Willdenowia 43: 13–24. June 2013. — Online ISSN 1868–6397; © 2013 BGBM Berlin-Dahlem. Stable URL: http://dx.doi.org/10.3372/wi.43.43102 Tetroncium magellanicum (Juncaginaceae) was described by Willdenow in 1808, based on material collected by Commerson at the Strait of Magellan during Bougainville's voyage around the world. Type material of this species was traced and a lectotype for the name is designated. A description of the species and notes on its ecology and conservation status are provided. For the first time, a detailed map showing the known distri…
