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.

CHEW Department of Botany, National University of Singapore, Lower Kent Ridge Road, Singapore 0511, Republic of Singapore 1 National Parks Board, Botanic Gardens, Cluny Road, Singapore 1025, Republic of Singapore EFFECTIVE PUBLICATION DATE: 15 MAR 1993 Abstract From field and hebarium studies, two new fern and 23 angiosperm taxa were found to have been pre viously overlooked or newly discovered in Singapore. Brief notes on their description, distribution and ·collecting localities are made for each. Introduction A comprehensive list of vascular plant species has been compiled for Singapore (Turner et a/., 1990) from literature and herbarium work. In the course of field work and examination of specimens at the Herbarium, Singapore Botanic Gardens (SING) and the Herbarium, Department of Botany, National University of Singapore (SINU), new records of species were made. Voucher specimens for each newly discovered taxon have been deposited in SINU and/or SING. New Records Adiantaceae I. Adiantum fructuosum Spreng. A large ornamental fern with bipinnate fronds which can grow up to 100 em long. It originates from the rainforest of tropical America where it is found from Mexico and the West Indies, southern Peru and Brazil. It appears to be naturalized in Singapore and occurs on shaded earth banks along Seton Close and Cluny Road. Here, the plants are about 40 em tall and freely fertile. (Specimen - Y.C. Wee 451) 2. Adiantum latifo/ium Lam. A tropical American fern, occurring naturally from Mexico to South America, as well as the Greater Antilles, Virgin Islands and Trinidad.

Lose the Plot: Cost-Effective Survey of the Peak Range, Central Queensland
Lose the plot: cost-effective survey of the Peak Range, central Queensland. Don W. Butlera and Rod J. Fensham Queensland Herbarium, Environmental Protection Agency, Mt Coot-tha Botanic Gardens, Mt Coot-tha Road, Toowong, QLD, 4066 AUSTRALIA. aCorresponding author, email: [email protected] Abstract: The Peak Range (22˚ 28’ S; 147˚ 53’ E) is an archipelago of rocky peaks set in grassy basalt rolling-plains, east of Clermont in central Queensland. This report describes the flora and vegetation based on surveys of 26 peaks. The survey recorded all plant species encountered on traverses of distinct habitat zones, which included the ‘matrix’ adjacent to each peak. The method involved effort comparable to a general flora survey but provided sufficient information to also describe floristic association among peaks, broad habitat types, and contrast vegetation on the peaks with the surrounding landscape matrix. The flora of the Peak Range includes at least 507 native vascular plant species, representing 84 plant families. Exotic species are relatively few, with 36 species recorded, but can be quite prominent in some situations. The most abundant exotic plants are the grass Melinis repens and the forb Bidens bipinnata. Plant distribution patterns among peaks suggest three primary groups related to position within the range and geology. The Peak Range makes a substantial contribution to the botanical diversity of its region and harbours several endemic plants among a flora clearly distinct from that of the surrounding terrain. The distinctiveness of the range’s flora is due to two habitat components: dry rainforest patches reliant upon fire protection afforded by cliffs and scree, and; rocky summits and hillsides supporting xeric shrublands.

Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks.
