What is Allium achaium Boiss. & Orph.? Disentangling the taxonomy of a Greek mountain species

Allium oreohellenicum Tzanoud., Tsakiri & Raus (Amaryllidaceae), endemic of the Greek mountains, is described and illustrated as a species new to science. Information regarding its cytology, geographical distribution and taxonomic relationships is also provided. Material belonging to A. oreohellenicum was formerly known/classified as A. achaium Boiss & Orph., a taxon described in 1882 based on a gathering by Orphanides from Mt Klokos (N Peloponnisos, Greece). A detailed study of the Orphanides gathering concerned revealed that it essentially belongs to A. frigidum Boiss. & Heldr., a taxon described 28 years earlier, and so the need for a new name

Taxonomic and functional plant diversity of the Santorini-Christiana island group (Aegean Sea, Greece)

This is the first attempt to analyse vascular plant diversity patterns regarding the seven vegetated islands of the Santorini archipelago (Aegean Sea, Greece) as a whole. Hitherto unpublished floristic records, combined with critical use of taxonomic and chorological information from previous and most recent literature, resulted in a total of 696 infrageneric taxa (species and subspecies) occurring in the area. Detailed qualitative and quantitative phytodiversity spectra per individual island are presented, and floristic dissimilarity (beta-diversity) between islands is considered. Spatial distribution of 28 chorological, ecological, vegetative and reproductive traits for each recorded taxon have been calculated in order to detect regional and fundamental patterns in functional biogeography beyond traditional species-based approaches, based on both taxonomic and functional components of diversity. Mediterranean species constitute the most abundant chorological element and therophytes the most abundant life-form element in the region. Surface area is the most influential variable contributing to species richness; very strong relationships in (1) species per area, (2) functional richness per area and (3) functional richness per species richness are revealed for the Santorini archipelago. Floristic cross-correlations revealed an overall high floristic heterogeneity among the individual islands. The phytodiversity assessment presented is undoubtedly of documentary value in consideration of expected future eruptive events in the area which may damage the plant cover at least on some of the involved islands to a yet unpredictable extent

Citation hygiene 1: "A. Br." : Addison Brown and Alexander Braun as authors of plant names

Die Autorbezeichnung „A. Br.“ kodiert nach dem empfohlenen internationalen Standard des Autorenlexikons von BRUMMITT & POWELL (Authors of Plant Names, Kew 1992) den amerikanischen Botaniker Addison Brown (1830–1913). Sie wird jedoch traditionell in hohem Maße unklar und verwirrend verwendet für Taxa, die der nahezu zeitgleich wirkende Deutsche Alexander Braun (1805–1877) aufgestellt hat. Durch unkritisch in Datenbanksysteme importierte Datensätze werden viele Namen infolgedessen als scheinbare Homonyme dieser beiden Autoren verwaltet. Alle von Alexander Braun beschriebenen Taxa sollten deshalb konsequent mit dem Standardkürzel „A. Braun“ versehen sein und nur mit diesem in Datenbanken eingepflegt werden.The author abbreviation “A. Br.” is recommended by BRUMMITT & POWELL (Authors of Plant Names, Kew 1992) to code the American botanist Addison Brown (1830–1913). However, it is also frequently and ambiguously applied to names of vascular plant taxa described by his contemporary German colleague Alexander Braun (1805–1877). Thus many plant names are run by electronic databases and bioinformatic systems as apparent homonyms made by the two authors. All names created by Alexander Braun should bear the author abbreviation “A. Braun” instead, necessarily so in electronic databases, in order to avoid pseudo-homonymy by uncritically imported data sets

Taxonomic, nomenclatural and floristic review of Amaranthaceae of Greece and neighbouring countries

The history and progress of floristic knowledge on Amaranthaceae occurring in Greece and adjacent Balkan countries are briefly outlined and changes in family circumscription and generic delimitation are addressed. The new combinations Amaranthus blitoides [var. blitoides] f. thellungii (Sennen ex Thell.) Raus and A. blitoides [var. reverchonii] f. densifolius (Uline & W. L. Bray) Raus are published. The names Achyranthes argentea Lam. and Amaranthus commutatus A. Kern. ex Hayek are lectotypified, the former a synonym of Achyranthes sicula (L.) All , the latter of Amaranthus blitum L. Amaranthus commutatus A. Kern. has long been known as a designation with no nomenclatural value for a fictitious taxon but is still erroneously accepted in current floristic online sources
