Box 524, Auckland Park 2006, Johannesburg, South Africa Received 4 November 2011; received in revised form 18 November 2011; accepted 21 November 2011 Abstract Asphodelus fistulosus or onionweed is recorded in South Africa for the first time and is the first record of an invasive member of the Asphodelaceae in the country. Only two populations of this plant have been observed, both along disturbed roadsides on the West Coast of South Africa.

  • Well-Known Plants in Each Angiosperm Order
    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers. Basal angiosperms – mostly aquatic plants Unplaced in order, placed in Amborellaceae family • Amborella trichopoda – one of the most ancient flowering plants Unplaced in order, placed in Nymphaeaceae family • Water lily • Cabomba (fanwort) • Brasenia (watershield) Ceratophyllales • Hornwort Austrobaileyales • Illicium (anise tree, star anise) Basal angiosperms - magnoliids Canellales • Drimys (winter's bark) • Tasmanian pepper Laurales • Bay laurel • Cinnamon • Avocado • Sassafras • Camphor tree • Calycanthus (sweetshrub, spicebush) • Lindera (spicebush, Benjamin bush) Magnoliales • Custard-apple • Pawpaw • guanábana (soursop) • Sugar-apple or sweetsop • Cherimoya • Magnolia • Tuliptree • Michelia • Nutmeg • Clove Piperales • Black pepper • Kava • Lizard’s tail • Aristolochia (birthwort, pipevine, Dutchman's pipe) • Asarum (wild ginger) Basal angiosperms - monocots Acorales

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Aquatic Vascular Plant Species Distribution Maps
    Appendix 11.5.1: Aquatic Vascular Plant Species Distribution Maps These distribution maps are for 116 aquatic vascular macrophyte species (Table 1). Aquatic designation follows habitat descriptions in Haines and Vining (1998), and includes submergent, floating and some emergent species. See Appendix 11.4 for list of species. Also included in Appendix 11.4 is the number of HUC-10 watersheds from which each taxon has been recorded, and the county-level distributions. Data are from nine sources, as compiled in the MABP database (plus a few additional records derived from ancilliary information contained in reports from two fisheries surveys in the Upper St. John basin organized by The Nature Conservancy). With the exception of the University of Maine herbarium records, most locations represent point samples (coordinates were provided in data sources or derived by MABP from site descriptions in data sources). The herbarium data are identified only to township. In the species distribution maps, town-level records are indicated by center-points (centroids). Figure 1 on this page shows as polygons the towns where taxon records are identified only at the town level.

Five major areas were used to describe the family distributions: Eurasia, North America, South America, Africa including Madagascar, and Australasia including New Guinea, New Caledonia, and New Zealand. In order to investigate the possible correspondence with continental breakup, the tree with its terminal distributions was fitted to the geological area cladogram «Eurasia, North America), (Africa, (South America, Australasia») and to alternative area cladograms using the TreeFitter program.

  • Resolution of Deep Angiosperm Phylogeny Using Conserved Nuclear Genes and Estimates of Early Divergence Times
    ARTICLE Received 24 Mar 2014 | Accepted 11 Aug 2014 | Published 24 Sep 2014 DOI: 10.1038/ncomms5956 OPEN Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times Liping Zeng1, Qiang Zhang2, Renran Sun1, Hongzhi Kong3, Ning Zhang1,4 & Hong Ma1,5 Angiosperms are the most successful plants and support human livelihood and ecosystems. Angiosperm phylogeny is the foundation of studies of gene function and phenotypic evolution, divergence time estimation and biogeography. The relationship of the five divergent groups of the Mesangiospermae (B99.95% of extant angiosperms) remains uncertain, with multiple hypotheses reported in the literature. Here transcriptome data sets are obtained from 26 species lacking sequenced genomes, representing each of the five groups: eudicots, monocots, magnoliids, Chloranthaceae and Ceratophyllaceae. Phylogenetic analyses using 59 carefully selected low-copy nuclear genes resulted in highly supported relationships: sisterhood of eudicots and a clade containing Chloranthaceae and Ceratophyllaceae, with magnoliids being the next sister group, followed by monocots. Our topology allows a re-examination of the evolutionary patterns of 110 morphological characters. The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation. 1 State Key Laboratory of Genetic Engineering and Collaborative Innovation Center for Genetics and Development, Ministry of Education Key Laboratoryof Biodiversity Sciences and Ecological Engineering, Institute of Plant Biology, Institute of Biodiversity Science, Center for Evolutionary Biology, School of Life Sciences, Fudan University, 220 Handan Road, Yangpu District, Shanghai 200433, China. 2 Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and the Chinese Academy of Sciences, Guilin 541006, China.
