NJB most cited papers 2013

Submitted by nordicjbotany on 7 October 2014.

 The most cited articles of those published in NJB in 2011 and 2012 span a wide flora of topics. They range from an updated index of Neotropical Annonaceae to new Basidiomycota-species and an overview of the use of the Global Biodiversity Information Facility. Notably, three publications on the taxonomy of Stipa are among the 10 most cited papers  in 2013. The most-cited list reflects the aim of NJB to publish studies that explore all aspects of the botanical biodiversity on Earth, and to publish papers in botany and mycology.

Biodiversity information goes public: GBIF at your service

Anders Telenius

As the precision and the scope of modeling in ecology, systematics and evolution progresses, scientific collections of biological objects, some of which are hundreds of years old, become increasingly more attractive as sources of information in combination with recent biological observations. Until recently the acquisition of such primary information has been a cumbersome and/or haphazard process, and a number of initiatives have been launched to create a set of tools enabling scientists to access existing data more easily. In times of severe global habitat loss, climate change and rapidly declining biological diversity, an increasing demand for information from researchers, decision-makers at various societal levels and the public in general can be anticipated.

The Global Biodiversity Information Facility (GBIF) now offers the most successful and certainly the most comprehensive running web service for complex searches on taxa, areas or particular datasets. Being the world's largest single biodiversity data portal, one obvious major strategic objective is to enable research that has hitherto been impossible. For example, large-scale modeling in ecology, systematics and evolution often requires extensive data sets spanning over long periods of time. Furthermore, the GBIF policy gives open and free access to everyone to digital biodiversity data. 


An updated index to Neotropical Annonaceae

Paul J. M. Maas, Lubbert Y. Th. Westra, Heimo Rainer, Adriana Q. Lobão and Roy H. J. Erkens

Annonaceae are a large pantropical family of trees and lianas. It is the most diverse family within the Magnoliales.The family contributes significantly to tree diversity in rain forests around the world. In 1990 an Index to generic names of Annonaceae was published and in 1994 an Index to Neotropical species of Annonaceae was compiled. Especially the latter proved an immensely useful tool for Neotropical botanists. Here, we present an updated Index of all valid names in Neotropical Annonaceae on the genus and species level. It also includes nomina nuda and orthographic variants. Reference and year of first publication, synonymy, and typification are mentioned. Several new combinations are made. In addition, some lectotypifications are proposed. A supplementary list is added of all Neotropical type collections.


A review of the lichen family Parmeliaceae – history, phylogeny and current taxonomy

Arne Thell, Ana Crespo, Pradeep K. Divakar, Ingvar Kärnefelt, Steven D. Leavitt, H. Thorsten Lumbsch and Mark R. D. Seaward

The largest family of lichen-forming fungi, the Parmeliaceae, is reviewed. It includes 79 genera in current use and ca 2726 species, a large majority of which belong to one of five main clades: the parmelioid, cetrarioid, usneoid, alectorioid and hypogymnioid. Recently, the estimated number of lichen species worldwide has increased to ca 28 000, mainly due to increased research activity on their biodiversity in tropical regions. The large majority of lichenized fungi are ascomycetes classified into ca 60 lichenized orders. The majority of these lichenized fungi belong to the almost entirely lichen-forming fungal order Lecanorales comprising 20 families. The Parmeliaceae is the largest family of lichen-forming ascomycetes and includes well-known groups such as beard-lichens, Usnea, and shield-lichens, Parmelia et al. After two centuries of taxonomic splitting, which accelerated in the late 1960s, the systematics of Parmeliaceae is gradually stabilizing with help of DNA-based phylogenies. 

Taxonomy on Stipa from Central Asia

Marcin Nobis

The genus Stipa L. contains about 60–70 species in central Asia. Between 30 and 40 of them grow in the Pamir Alai Mts. In 3 articles published in NJB, the author describes Stipa narynica M. Nobis sp. nov. from western Kyrgyzstan, as well as providing observations on members of the Stipa tianschanica complex, with particular reference to Tajikistan. In addition, Stipa ×brozhiana M. Nobis nothosp. nov. (Poaceae) is described and illustrated. The taxon belongs to sect. Smirnovia Tzvel. and originated from the hybridization of species belonging to sect. Smirnovia and Barbatae Junge. 

Newly described Hymenochaete rhododendricola and H. quercicola spp. nov. (Basidiomycota, Hymenochaetales) from Tibet

Shuang-Hui He and Hai-Jiao Li

In 2010, an intensive survey of wood-inhabiting fungi in Tibet was carried out, and two species of Hymenochaete were found that are distinctly different from all known species of the genus.  Hymenochaete rhododendricola is distinct in the genus by its large and heavily enmeshed setae, and growing on dead branches of Rhododendron. Hymenochaete quercicola differs from other species by its smooth or tuberculate hymenophore, presence of a cortex, relatively large and oblong-ellipsoid basidiospores, and living on dead branches of Quercus.

Hymenostegia elegans and H. robusta spp. nov. (Leguminosae–Caesalpinioideae) from Gabon

Jan Wieringa and Barbara Mackinder 

Leguminosae, the third largest family of angiosperms currently comprises three subfamilies of which Caesalpinioideae is the smallest and contains about 2250 species in 171 genera. About half of all caesalpinioid genera belong to tribe Detarieae including the tropical African genus Hymenostegia. As currently circumscribed it accommodates 15 morphologically diverse species and is polyphyletic. We have observed among the holdings of Hymenostegia (Leguminosae: Caesalpinioideae) in several major herbaria that many of the specimens determined as H. klainei Pierre ex Pellegr. are not identified correctly and instead represent undescribed taxa.  Two such previously unrecognised taxa, both new species from Gabon, Hymenostegia elegans Wieringa and Mackinder and Hymenostegia robusta Wieringa and Mackinder are described here accompanied by a distribution map, illustrations and conservation assessments. Both species have a limited distribution area and are assessed as ‘Vulnerable’ and ‘Endangered’, respectively. This publication brings the total number of species in Hymenostegia s.s. to nine.

Amaranthus powellii subsp. cacciatoi comb. et stat. nov. (Amaranthaceae)

Duilio Iamonico

Amaranthus L. is a genus of about 70 species, of which about 40 are native to the Americas, with the remaining native to Australia, Africa, Asia and Europe (Costea et al. 2001). This genus is taxonomically problematic due to nomenclatural confusion resulting from frequent misapplication of names. Amaranthus powellii S. Watson subsp. cacciatoi (Aellen ex Cacciato) Iamonico comb. et stat. nov. (Amaranthaceae) is proposed and a detailed description is provided. The new taxon is compared with A. powellii S. Watson subsp. powellii and subsp. bouchonii (Thell.) Costea & Carretero.

Third Primulina species in Zhejiang Province, China

Jian Li, Yue Wang, Guo-Jun Hua and Fang Wen

A wild, flowering Primulina (former Chirita) species was found in the subtropical forest of Zhejiang Province, China and at the same time also in Lin'an, Hangzhou. The collected plants represent a new species of the genus Primulina. The new species reported in this paper is the third Primulina-species found in Zhejiang Province. The epithet xiziae is used to perpetuate the memory of one of the beauties of Old China, Xishi. It is said that Xishi was so beautiful, having no equal in spring and autumn and the ‘Warring states period’ of China. She was from Zhejiang and her nickname was Xizi. Primulina xiziae grows only on small outcrops of shaded moist limestone cliffs under subtropical evergreen broad-leaved forests in Zhejiang Province at 70–110 m a.s.l.
