Himatanthus as accepted here comprises nine Neotropical species. The infrageneric and infraspecific taxa proposed by Plumel and Müller, Woodson and Plumel, respectively, are not recognized. Lectotypes are designated for the following names: P. floribunda, P. floribunda var. crassipes, P. lancifolia, P. tarapotensis and P. warmingii. Neotypes are designated for H. rigidus, P. ambigua, P. latifolia and P. lancifolia var. microphylla. An examination of the types of both H. phagedaenicus and H. bracteatus showed that recently these names have been misapplied. Complete synonymies are provided for the nine recognized species of Himatanthus. Also, the new combination H. revolutus (Huber) Spina & Kinoshita is effected.

DOI: http://dx.doi.org/10.12705/626.16 INTRODUCTION NOMENCLATURAL PROBLEMS IN HIMATANTHUS Woodson (1938) recognized Himatanthus Willd. as be- ing restricted to South America and distinct from Plume- “Himatanthus” was first described in an unpublished ria L. based on the following morphological characters: large manuscript by Willdenow based on the single species “Hi- and showy bracts, petaloid or foliaceous, caducous, subtended matanthus rigida Willd.”, described from the specimen by numerous minute, pectinate, adaxial glands at the base; Sieber s.n. collected between 1801 and 1807 in the state of calyx lobes very irregular in size, gradually acuminate and Pará, northern Brazil. These two names were later validly eglandular at the tip, or the calyx inconspicuous; ventral loculi published by Willdenow in Roemer & Schultes (1819), the of the anthers not protuberant; and seeds provided with a “Reliqu. Willd. MS.” statement representing direct associa- broad, more or less concentric, papery wing. Based on these tion of Willdenow with both the names and the diagnosis (Art. differences, Woodson (1938) considered Himatanthus to be 46.3 Ex. 12, McNeill & al., 2012). Formerly, Himatanthus was comprised of six species and two varieties and Plumeria of treated as feminine (Willdenow in Roemer & Schultes 1819; seven species, with four taxa restricted to North and Central Woodson 1938) possibly due to the tendency to treat classi- America. cal tree names as feminine (Art. 62.1, McNeill & al., 2012). Recently Himatanthus was revised by Plumel (1990, 1991) Technically, Himatanthus ought to be neuter as it is based on who proposed two subgenera, “H. subg. Obovatae” (H. subg. the Greek word anthos, but it is treated as masculine in ac- Himatanthus) and H. subg. Lanceolatae Plumel; a new spe- cordance with tradition, under the current Code (Art, 62.2(c), cies, H. stenophyllus Plumel; and eight new combinations: McNeill & al., 2012). H. drasticus (Mart.) Plumel, H. fallax (Müll. Arg.) Plumel, Himatanthus remained monotypic, until Woodson (1938) H. tarapotensis (Schum. ex Markgr.) Plumel, H. speciosus transferred several species of Plumeria to Himatanthus; he (Müll. Arg.) Plumel, H. bracteatus var. revolutus (Huber) treated H. rigidus Willd. ex Schult. as a synonym of H. articu- Plumel, H. attenuatus var. malongo (Müll. Arg.) Plumel, latus (Vahl) Woodson. Plumel (1991) incorrectly designated the H. attenuatus var. obtusifolius (Müll. Arg.) Plumel, and type of Plumeria articulata Vahl (≡ Himatanthus articulatus H. obovatus var. velutinus (Müll. Arg.) Plumel. In total, Plumel (Vahl) Woodson) as the type of Himatanthus on the grounds (1990, 1991) recognized thirteen species and eight varieties in that the holotype of H. rigidus Willd., the only species included Himatanthus. In the present paper a revision of the nomencla- in Willdenow’s original circumscription of Himathanthus, had ture of Himatanthus (Apocynaceae) is presented as part of a been destroyed. Plumel’s action has no standing and the neo- taxonomic revision by Spina (2004). type of H. rigidus proposed herein is to be taken as the type of Himatanthus. 1304 Version of Record (identical to print version). TAXON 62 (6) • December 2013: 1304–1307 Spina & al. • Typifications and nomenclatural novelties in Himatanthus In the protologue of some species of Plumeria Müller- term “holotype” is corrected to “lectotype” (Art. 9.9, McNeill Argoviensis (1860, 1869) and Pilger (1901) did not indicate a & al., 2012). Plumel (1991) treated Plumeria floribunda as a holotype. We designate lectotypes for the following names: synonym of H. lancifolius (Müll. Arg.) Woodson and cited Plumeria floribunda Müll. Arg., Plumeria floribunda var. Saint Hilaire s.n. (Minas Gerais, Casa de Teilha) in P as the crassipes Müll. Arg., Plumeria lancifolia Müll. Arg., Plume- type of P. floribunda.

  • Anti-Malarial Activity and Toxicity Assessment of Himatanthus
    Vale et al. Malaria Journal (2015) 14:132 DOI 10.1186/s12936-015-0643-1 RESEARCH Open Access Anti-malarial activity and toxicity assessment of Himatanthus articulatus, a plant used to treat malaria in the Brazilian Amazon Valdicley V Vale1, Thyago C Vilhena1, Rafaela C Santos Trindade2, Márlia Regina C Ferreira2, Sandro Percário3,7, Luciana F Soares4, Washington Luiz A Pereira5, Geraldo C Brandão8, Alaíde B Oliveira1,4, Maria F Dolabela1,6 and Flávio De Vasconcelos1* Abstract Background: Plasmodium falciparum has become resistant to some of the available drugs. Several plant species are used for the treatment of malaria, such as Himatanthus articulatus in parts of Brazil. The present paper reports the phyto-chemistry, the anti-plasmodial and anti-malarial activity, as well as the toxicity of H. articulatus. Methods: Ethanol and dichloromethane extracts were obtained from the powder of stem barks of H. articulatus and later fractionated and analysed. The anti-plasmodial activity was assessed against a chloroquine resistant strain P. falciparum (W2) in vitro, whilst in vivo anti-malarial activity against Plasmodium berghei (ANKA strain) was tested in mice, evaluating the role of oxidative stress (total antioxidant capacity - TEAC; lipid peroxidation – TBARS, and nitrites and nitrates - NN). In addition, cytotoxicity was evaluated using the HepG2 A16 cell-line. The acute oral and sub-chronic toxicity of the ethanol extract were evaluated in both male and female mice. Results: Plumieride was isolated from the ethyl acetate fraction of ethanol extract, Only the dichloromethane extract was active against clone W2. Nevertheless, both extracts reduced parasitaemia in P. berghei-infected mice.

  • Phylogeny and Systematics of the Rauvolfioideae
    PHYLOGENY AND SYSTEMATICS Andre´ O. Simo˜es,2 Tatyana Livshultz,3 Elena OF THE RAUVOLFIOIDEAE Conti,2 and Mary E. Endress2 (APOCYNACEAE) BASED ON MOLECULAR AND MORPHOLOGICAL EVIDENCE1 ABSTRACT To elucidate deeper relationships within Rauvolfioideae (Apocynaceae), a phylogenetic analysis was conducted using sequences from five DNA regions of the chloroplast genome (matK, rbcL, rpl16 intron, rps16 intron, and 39 trnK intron), as well as morphology. Bayesian and parsimony analyses were performed on sequences from 50 taxa of Rauvolfioideae and 16 taxa from Apocynoideae. Neither subfamily is monophyletic, Rauvolfioideae because it is a grade and Apocynoideae because the subfamilies Periplocoideae, Secamonoideae, and Asclepiadoideae nest within it. In addition, three of the nine currently recognized tribes of Rauvolfioideae (Alstonieae, Melodineae, and Vinceae) are polyphyletic. We discuss morphological characters and identify pervasive homoplasy, particularly among fruit and seed characters previously used to delimit tribes in Rauvolfioideae, as the major source of incongruence between traditional classifications and our phylogenetic results. Based on our phylogeny, simple style-heads, syncarpous ovaries, indehiscent fruits, and winged seeds have evolved in parallel numerous times. A revised classification is offered for the subfamily, its tribes, and inclusive genera. Key words: Apocynaceae, classification, homoplasy, molecular phylogenetics, morphology, Rauvolfioideae, system- atics. During the past decade, phylogenetic studies, (Civeyrel et al., 1998; Civeyrel & Rowe, 2001; Liede especially those employing molecular data, have et al., 2002a, b; Rapini et al., 2003; Meve & Liede, significantly improved our understanding of higher- 2002, 2004; Verhoeven et al., 2003; Liede & Meve, level relationships within Apocynaceae s.l., leading to 2004; Liede-Schumann et al., 2005). the recognition of this family as a strongly supported Despite significant insights gained from studies clade composed of the traditional Apocynaceae s.

  • Floristic Composition and Edge-Induced Homogenization in Tree Communities in the Fragmented Atlantic Rainforest of Rio De Janeiro, Brazil
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol. 9 (2): 852-876, 2016 Research Article Floristic composition and edge-induced homogenization in tree communities in the fragmented Atlantic rainforest of Rio de Janeiro, Brazil. Oliver Thier1* and Jens Wesenberg2 1 University of Leipzig, Institute for Biology I, Systematic Botany and Functional Biodiversity, Johannisallee 21, 04103 Leipzig, Germany. 2 Senckenberg Museum of Natural History Görlitz, Botany Department, Am Museum 1, 02826 Görlitz, Germany. * Corresponding author. Email: [email protected] Abstract This study investigates the changes of tree species composition and diversity along the gradient from fragment edge to interior, and between edge and interior habitats, on a regional scale, in nine Atlantic forest fragments (6–120 ha), in southeastern Brazil. A total of 1980 trees (dbh ≥ 5 cm) comprising 252 species, 156 genera and 57 families were surveyed using the point-centered quarter method. From the fragment edge towards the interior the proportion of shade-tolerant trees increased continuously. The majority of all trees within the first 100 m from the edge belonged to the pioneer-guild. Floristic dissimilarity was found to be higher among interior habitats of different fragments than among the corresponding edge areas or among different small fragments. Species diversity increased along the edge-interior gradient 1.5 times within the first 250 m. Our results support previous findings that the establishment of edge-affected habitats leads to tree species impoverishment and homogenization via the dominance and proliferation of pioneer species in the forest edges of severely fragmented tropical landscapes. We argue that conservation strategies which include the creation of buffer zones between forest edges and the matrix will be more efficient than the establishment of narrow corridors to connect fragments and protected areas.

David Sites Clarke By Craig M. Johnson Carol L. Kelloff, Sara N. Alexander, V. A. Funk,with contributions and H. David by Clarke Stanley A. Ahler, Herbert Haas, and Georges Bonani SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institu- tions throughout the world. Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affilia- tion with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines.
