A Casual Cantharophily: the Meeting Between Astylus
Journal of Pollination Ecology, 5(12), 2011, pp 86-89 — Short Communication — A CASUAL CANTHAROPHILY : THE MEETING BETWEEN ASTYLUS VARIEGATUS (C OLEOPTERA : MYLERIDAE ) AND OXYPETALUM BANKSII (A POCYNACEAE : ASCLEPIADOIDEAE ) Milene Faria Vieira* and Rúbia Santos Fonseca Departamento de Biologia Vegetal, Universidade Federal de Viçosa, 36570-000 Viçosa, Minas Gerais, Brazil Abstract —Cantharophily is reported for the first time in a Brazilian asclepiad, involving the mylerid Astylus variegatus and the nectariferous flowers of Oxypetalum banksii , a plant mainly pollinated by wasps. The use of nectar as food by A. variegatus , considered pollinivorous and granivorous, is also novel. The mutual interaction described here is an example of a plant-pollinator interaction with generalist insects visiting a plant with a specialized pollination system. It’s also temporary and occasional and, therefore, is often overlooked in studies of plant-pollinator interactions. In this study, we found that the casual meeting between O. banksii and A. variegatus was a key event for the reproduction of both. Key words: Asclepiad, Atlantic Forest, Brazil, beetles, specialized pollination, wasps The asclepiads (Apocynaceae: Asclepiadoideae, sensu (Asclepias woodii , Sisyranthus trichostomus and Endress & Bruyns 2000) have highly elaborate and Xysmalobium involucratum ) and chafer beetles (Scarabaeidae: complicated flowers. There is an unusual synorganization Cetoniini). Shuttleworth and Johnson (2008) described, also between parts and also between organs of different categories in South Africa, a bimodal pollination system in the asclepiad (Endress 1994). This has led to the evolutionary origin of Xysmalobium undulatum ; its pollination is performed by two new organs that are not present in other angiosperm groups in unrelated species (or functional groups) of pollinators: chafer this combination: corona (more or less well developed beetles and pompilid wasps (Hymenoptera: Pompilidae). -

Chapter I. Isolation of Natural Products As Anticancer Drugs I.1
Chapter I. Isolation of Natural Products as Anticancer Drugs I.1 Introduction Human beings have relied on natural products as a resource of drugs for thousands of years. Plant-based drugs have formed the basis of traditional medicine systems that have been used for centuries in many countries such as Egypt, China and India.1 Today plant-based drugs continue to play an essential role in health care. It has been estimated by the World Health Organization that 80% of the population of the world rely mainly on traditional medicines for their primary health care.2 Natural products also play an important role in the health care of the remaining 20% people of the world, who mainly reside in developed countries. Currently at least 119 chemicals, derived from 90 plant species, can be considered as important drugs in one or more countries.3 Studies in 1993 showed that plant-derived drugs represent about 25% of the American prescription drug market, and over 50% of the most prescribed drugs in the US had a natural product either as the drug or as the starting point in the synthesis or design of the agent.4 There are more than 250,000 species of higher plants in the world, and almost every plant species has a unique collection of secondary constituents distributed throughout its tissues. A proportion of these metabolites are likely to respond positively to an appropriate bioassay, however only a small percentage of them have been investigated for their potential value as drugs. In addition, much of the marine and microbial world is still unexplored, and there are plenty of bioactive compounds awaiting 1 Balandrin, N. -
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. -

Shuttleworth, S.D. Johnson School of Biological and Conservation Sciences, University of KwaZulu-Natal Pietermaritzburg, Private Bag X01, Scottsville 3209, South Africa Received 1 April 2009; received in revised form 21 July 2009; accepted 27 July 2009 Abstract Studies of pollination in southern African asclepiads (aside from the stapeliads and members of the genus Ceropegia) are remarkably scarce given the diversity of asclepiad species in the region. In this study, we report new observations of insect flower visitors and their pollen loads for 15 species of South African asclepiads in the genera Asclepias, Aspidoglossum, Miraglossum, Pachycarpus, Periglossum, Woodia and Xysmalobium. Nectar properties are also presented for some species. Four specialized pollination systems are suggested by these observations: (1) pollination by wasps in the genus Hemipepsis (Hymenoptera: Pompilidae) in eight species, (2) pollination by chafer beetles (Scarabaeidae: Cetoniinae) in three species, (3) pollination by honeybees, Apis mellifera (Hymenoptera: Apidae) in two species, and (4) pollination by flies from various families in one species. The pollination system of Asclepias crispa remains unclear but appears to be one of generalized insect pollination. Future research is likely to confirm the preponderance of specialized pollination systems within this group of plants in southern Africa. © 2009 SAAB. Published by Elsevier B.V.

(Malvaceae) from the Guinea Highlands (West Africa) M. Cheek1,*, P.K. Haba2,3, S. Cisse4 Key words Abstract Hibiscus fabiana Cheek (sect. Furcaria, Malvaceae) is described from the Guinea Highlands of West Africa, and its taxonomic affinities and ecology are considered. Hibiscus fabiana has previously been confused Bowal with H. rostellatus but has red fleshy calyx ribs (vs not red and non-fleshy), the calyx surface is glabrous apart from conservation 1-armed bristles (vs densely covered in minute white stellate hairs and bristles 2–5-armed), the leaves 3(–5)-lobed, Furcaria bases truncate to rounded (vs 5-lobed, cordate). The conservation status of the new species is assessed using the Guinea Highlands IUCN 2012 standard as Vulnerable. In the context of the recently discovered extinction of the Guinean endemic Hibiscus Inversodicraea pygmaea G.Taylor (Podostemaceae), we discuss the 30 new species to science discovered in Guinea Important Plant Areas since 2005, all but one of which are also range-restricted and threatened, usually by development or habitat loss. We Simandou consider it urgent to avoid their extinction, ideally with in situ conservation using an Important Plant Areas approach.

Naidoo, J.N Samuels, A. Nicholas and E. Rampersad School of Biological and Conservation Sciences, University of KwaZulu Natal, Private Bag X54001, Durban, 4000, South Africa Xysmalobium undulatum (L.) R.Br. belongs to the family Apocynaceae (subfamily Asclepiadoideae) and is a large perennial herb that grows throughout the grassland regions of southern Africa. It is known on the European market by the name Uzara, While primarily used as an antidiarrhoeal and for menstrual cramps, X. undulatum is also used in the treatment of a variety of other ailments, including skin diseases, fever, coughing, influenza, urinary tract infections, and gonorrhoea. Although there are numerous studies available on its pharmacology and taxonomy, no studies have been conducted on its leaf micromorphology [1]. This study aims to redress this by investigating the foliar micromorphology and relating its findings to the possible functional roles played in the plant. Leaves were prepared for scanning electron microscopy using conventional procedures. Observations with the SEM revealed a densely pubescent indumentum bearing numerous probably non-glandular hair-like trichomes on both the abaxial and adaxial leaf surfaces (Figs.1&2). However in older leaf samples very few trichomes were present. The trichomes are more abundant on the abaxial leaf surfaces where they are mainly distributed on the veins (Fig.2). They are characterised as being septate, uniseriate and erect. Each trichome possesses a prominent basal cellular pedestal (Fig.1). The surface of the trichomes displays numerous blunt warty outgrowths. -
