A monograph of Heterospathe (Areceae, Arecaceae) in New Guinea
A revision of the genus Heterospathe Scheff. in New Guinea and immediately adjacent islands is presented. We recognise 14 species for this area. Taxonomic and nomenclatural changes are outlined, and each species is thoroughly described, mapped and illustrated. A key to the species in the area is included as well...Petoe, Peter ; Baker, William

The composition of the aphid fauna (Insecta, Hemiptera) of the Royal Botanic Gardens, Kew
At least a dozen species of aphids (Insecta, Hemiptera) of non-native origin have expanded their range in Europe, however the importance of botanic gardens in this phenomenon has not been studied previously in detail. As a case study, investigations on the species composition and host range of Aphidomorpha in the...Wieczorek, Karina ; Fulcher, Tim ; Chłond, Dominik

Willow carr fungi
Preparation of this two-part article, introducing groups of fungi found in willow carr, was prompted by three considerations. Firstly, the FM editorial panel wanted to follow up the series on alder associates (Ainsworth, 2010; Kibby, 2010; Robinson, 2010) with a corresponding series on fungi associated with willow carr to provide...Ainsworth, A.

Two new species, Cyrtandra bungahijau and C. vittata, and notes on Cyrtandra (Gesneriaceae) from Yapen Island, Indonesia
Two new species of Cyrtandra (Gesneriaceae) are described; one apparently endemic to Yapen Island, Tanah Papua, the other present in Tanah Papua and in Papua New Guinea: both species are described and illustrated, and preliminary conservation assessments given. Notes on the identity of other known collections of Cyrtandra from Yapen...Atkins, H ; Heatubun, C ; Galloway, L ; Bramley, Gemma

Solid-State Biology and Seed Longevity: A Mechanical Analysis of Glasses in Pea and Soybean Embryonic Axes
The cytoplasm of anhydrobiotes (organisms that persist in the absence of water) solidifies during drying. Despite this stabilization, anhydrobiotes vary in how long they persist while dry. In this paper, we call upon concepts currently used to explain stability of amorphous solids (also known as glasses) in synthetic polymers, foods,...Ballesteros, Daniel ; Walters, Christina

Assessing Specialized Metabolite Diversity in the Cosmopolitan Plant Genus Euphorbia L.
Coevolutionary theory suggests that an arms race between plants and herbivores yields increased plant specialized metabolite diversity and the geographic mosaic theory of coevolution predicts that coevolutionary interactions vary across geographic scales. Consequently, plant specialized metabolite diversity is expected to be highest in coevolutionary hotspots, geographic regions, which exhibit strong...Ernst, Madeleine ; Nothias, Louis-Félix ; van der Hooft, Justin ; Silva, Ricardo ; Saslis-Lagoudakis, Haris …

Phylogeny of the tribe Marsdenieae (Apocynaceae), reinstatement of Ruehssia and the taxonomic treatment of the genus in Brazil
The Marsdenieae (Asclepiadoideae, Apocynaceae) comprise approximately 750 species and 26 accepted genera, half of which contain just one or two species. The tribe has been under-represented in phylogenetic studies to date, most of which have focussed on the ornamental paleotropical genus Hoya and related genera. American Marsdenieae are all currently...Espírito Santo, Fabio da Silva do ; Rapini, Alessandro ; Ribeiro, Patrícia Luz ; Liede-Schumann, Sigrid ; Goyder, David J. …

The rediscovery and delimitation of Elatostema setulosum W.T.Wang (Urticaceae)
Of the 280 species of Elatostema documented in China, 189 are known only from a single collection. Elatostemasetulosum is one such species, having been known only from the type collection for nearly half a century, until recent field investigations in Guangxi. Due to its morphological similarity to E.huanjiangense and E.tetracephalum,...Fu, Long-Fei ; Monro, Alexandre ; Wen, Fang ; Xin, Zi-Bing ; Wei, Yi-Gang …

Calyx (con)fusion in a hyper-diverse genus: Parallel evolution of unusual flower patterns in Eugenia (Myrtaceae)
Eugenia has a pantropical distribution and comprises ca. 1000 species found mostly in the Neotropics. Recent DNA based phylogenies show that unusual flower morphology of ‘eugenioid’ collections, e.g. fused calices that open by tearing, consistently emerged within Eugenia. These results emphasize a demand to revaluate flower morphology in a phylogenetic...Giaretta, Augusto ; Vasconcelos, Thais ; Mazine, Fiorella Fernanda ; Faria, Jair Eustáquio Quintino ; Flores, Rodolfo …

Revision and new species of the African genus Mischogyne (Annonaceae)
Mischogyne (Annonaceae, tribe Monodoreae) is a genus of small- to medium-sized tropical trees and shrubs. It is characterised by a combination of: (1) stamens and carpels on a more or less extended torus; (2) carpels divergent from each other at the apex of the torus above the anthers; (3) anthers...Gosline, George ; Marshall, Andrew R. ; Larridon, Isabel

Illegal wildlife trade and the persistence of “plant blindness”
This review investigates the ways in which “plant blindness,” first described by Wandersee and Schussler (1999, p. 82) as “the misguided anthropocentric ranking of plants as inferior to animals,” intersects with the contemporary boom in research and policy on illegal wildlife trade (IWT). We argue that plants have been largely...Margulies, Jared D. ; Bullough, Leigh‐Anne ; Hinsley, Amy ; Ingram, Daniel J. ; Cowell, Carly …

The viability of a breeding programme for ash in the British Isles in the face of ash dieback
To evaluate the viability and feasibility of a future breeding programme to produce trees resistant to an emerging pest or pathogen, it is helpful to ask the following questions: How much variation in resistance exists in tree populations? To what extent is this resistance heritable? How many genetic loci are...Plumb, William J. ; Coker, Timothy L. R. ; Stocks, Jonathan ; Woodcock, Paul ; Quine, Christopher …

A Target Capture-Based Method to Estimate Ploidy From Herbarium Specimens
Whole genome duplication (WGD) events are common in many plant lineages, but the ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most species. Standard methods for ploidy determination are chromosome counting and flow cytometry approaches. While flow cytometry approaches typically use fresh tissue, an increasing number...Viruel, Juan ; Conejero, María ; Hidalgo, Oriane ; Pokorny, Lisa ; Powell, Robyn …

Information gaps in indigenous and local knowledge for science-policy assessments
The need to understand nature’s contributions to people and across a broad spectrum of cultures and ecosystems is increasingly advocated in science assessments and policy decision-making for sustainability. However, for services such as food and medicine, gaps in existing studies on indigenous and local knowledge may preclude inclusive assessments. Here,...Cámara-Leret, Rodrigo ; Dennehy, Zoe
