  • Stillingia: a Newly Recorded Genus of Euphorbiaceae from China

We report here for the first time the occurrence of a member of the genus in China, Stillingia lineata subsp. pacifica. The distribution of the genus in China is apparently narrow, known only from Pingzhou and Wanzhou Islands of the Wanshan Archipelago in the South China Sea, which is close to the Pearl River estuary. This study updates our knowledge on the geographic distribution of the genus, and provides new palynological data as well. Key words: Island, Hippomaneae, South China Sea, Stillingia lineata Introduction During the last decade, hundreds of new plant species or new species records have been added to the flora of China. Nevertheless, newly described or newly recorded plant genera are not discovered and reported very often, suggesting that botanical expedition and plant survey at the generic level may be advanced in China. As far as we know, only six and eight angiosperm genera respectively have been newly described or newly recorded from China within the last ten years (Qiang et al.

  • The Framework Species Approach to Forest Restoration: Using Functional Traits As Predictors of Species Performance
    - 1 - The Framework Species Approach to forest restoration: using functional traits as predictors of species performance. Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Hannah Betts July 2013 - 2 - - 3 - Abstract Due to forest degradation and loss, the use of ecological restoration techniques has become of particular interest in recent years. One such method is the Framework Species Approach (FSA), which was developed in Queensland, Australia. The Framework Species Approach involves a single planting (approximately 30 species) of both early and late successional species. Species planted must survive in the harsh conditions of an open site as well as fulfilling the functions of; (a) fast growth of a broad dense canopy to shade out weeds and reduce the chance of forest fire, (b) early production of flowers or fleshy fruits to attract seed dispersers and kick start animal-mediated seed distribution to the degraded site. The Framework Species Approach has recently been used as part of a restoration project in Doi Suthep-Pui National Park in northern Thailand by the Forest Restoration Research Unit (FORRU) of Chiang Mai University. FORRU have undertaken a number of trials on species performance in the nursery and the field to select appropriate species. However, this has been time-consuming and labour- intensive. It has been suggested that the need for such trials may be reduced by the pre-selection of species using their functional traits as predictors of future performance. Here, seed, leaf and wood functional traits were analysed against predictions from ecological models such as the CSR Triangle and the pioneer concept to assess the extent to which such models described the ecological strategies exhibited by woody species in the seasonally-dry tropical forests of northern Thailand.

  • Revision of the Genus Cleidion (Euphorbiaceae) in Malesia
    BLUMEA 50: 197–219 Published on 22 April 2005 http://dx.doi.org/10.3767/000651905X623373 REVISION OF THE GENUS CLEIDION (EUPHORBIACEAE) IN MALESIA KRISTO K.M. KULJU & PETER C. VAN WELZEN Nationaal Herbarium Nederland, Universiteit Leiden branch, P.O. Box 9514, 2300 RA Leiden, The Netherlands; e-mail: [email protected], [email protected] SUMMARY A revision of the Malesian species in the genus Cleidion is presented. Cleidion javanicum is shown to be the correct name for the widespread type species (instead of the name C. spiciflorum). A new species, C. luziae, resembling C. javanicum, is described from the Moluccas, New Guinea and the Solomon Islands. In addition, C. salomonis is synonymised with C. papuanum and C. lanceolatum is treated as a variety of C. ramosii. In total 7 Malesian Cleidion species are recognized. Cleidion megistophyllum from the Philippines cannot reliably be confirmed to belong to the genus due to lack of information and specimens and is treated as a doubtful species. Key words: Cleidion, Acalypheae, Cleidiinae, revision, taxonomy, Malesia. INTRODUCTION Cleidion is a pantropical genus belonging to the large angiosperm family Euphorbiaceae s.s. It was described by Blume (1825), who included a single species C. javanicum1. The first revision was made by Müller Argoviensis (1865, 1866). His work was fol- lowed by the comprehensive treatment of Pax & Hoffmann (1914), which included 17 species. Pax & Hoffmann excluded the section Discocleidion Müll.Arg. which differs from Cleidion by the presence of a staminate and pistillate disc (in Cleidion a disc is absent), stipellate and palmatinerved leaves (in Cleidion the leaves are non-stipellate and pinnatinerved), and differences in anther type.

  • Influence of Altitude and Host-Plant Species on Gall Distribution in Colliguaja Spp
    Revista Chilena de Historia Natural 72: 305-313, 1999 Influence of altitude and host-plant species on gall distribution in Colliguaja spp. (Euphorbiaceae) in central Chile Influencia de la altitud y la especie de planta hospedadora sobre la distribuci6n de cecidias en Colliguaja spp. (Euphorbiaceae) en Chile central EDUARDO FUENTES-CONTRERAS, ERNESTO GIANOLI, PAULA P. CABALLERO & HERMANN M. NIEMEYER Departamento de Ciencias Ecologicas, Facultad de Ciencias, Universidad de Chile, Casilla 653, Santiago, Chile ABSTRACT The shrub genus Colliguaja (Euphorbiaceae) shows a characteristic pattern of altitudinal distribution in central Chile. At lower altitudes it is represented by C. odorifera, at middle elevation by the putative hybrid C. salicifolia and at upper altitudes by C. integerrima. Flower buds of Colliguaja spp. are galled by gall-midges and also show the presence of associated parasitoids and hyperparasitoids. In this study we evaluated the effect of altitude and Colliguaja species on the distribution and abundance of flower galls resulting from parasitoid attack. Analysis of leaf morphology was used to represent either putative hybridisation or a host-plant species transition at different altitudes, while gall prevalence and relative abundance were measured as dependent variables. Gall prevalence and relative abundance decreased significantly as altitude increased, and leaf morphology indicated a host-plant transition from C. odorifera through C. salicifolia to C. integerrima. Path analysis revealed that altitude had a stronger direct effect on relative abundance of galls than host-plant, while the influence of host-plant hybridisation or species transition was mainly mediated by changes in elevation. Key-words: Mediterranean matorral, elevation, flower galls, Colliguaja. RESUMEN El genero Colliguaja (Euphorbiaceae) presenta un patron de distribucion altitudinal caracterfstico en Chile central.

    IAWA Journal, Vol. 26 (1), 2005: 1-68 WOOD ANATOMY OF THE SUBFAMILY EUPHORBIOIDEAE A comparison with subfamilies Crotonoideae and Acalyphoideae and the implications for the circumscription of the Euphorbiaceae Alberta M. W. Mennega Nationaal Herbarium Nederland, Utrecht University branch, Heidelberglaan 2, 3584 es Utrecht, The Netherlands SUMMARY The wood anatomy was studied of 82 species from 34 out of 54 genera in the subfamily Euphorbioideae, covering all five tribes recognized in this subfamily. In general the woods show a great deal of similarity. They are charac­ terized by a relative paucity of vessels, often arranged in short to long, dumbbell-shaped or twin, radial multiples, and by medium-sized to large intervessel pits; fibres often have gelatinous walls; parenchyma apotracheal in short, wavy, narrow bands and diffuse-in-aggregates; mostly uni- or only locally biseriate rays, strongly heterocellular (except Hippomane, Hura and Pachystroma). Cell contents, either silica or crystals, or both together, are nearly always present and often useful in distinguishing between genera. Radiallaticifers were noticed in most genera, though they are scarce and difficult to trace. The laticifers are generally not surrounded by special cells, except in some genera of the subtribe Euphorbiinae where radiallaticifers are comparatively frequent and conspicuous. Three ofthe five tribes show a great deal of conformity in their anatomy. Stomatocalyceae, however, stand apart from the rest by the combination of the scarcity of vessels, and mostly biseriate, vertically fused and very tall rays. Within Euphorbieae the subtribe Euphorbiinae shows a greater vari­ ation than average, notably in vessel pitting, the frequent presence of two­ celled parenchyma strands, and in size and frequency of the laticifers.
