Phylogenetics and evolution of a newly demonstrated lineage of carnivorous monocots Carnivorous plants consume animals to obtain mineral nutrients, including nitrogen and phosphorus, to enhance growth, competitive ability and reproduction in nutrient-poor environments. I demonstrate that Triantha occidentalis (Tofieldiaceae, Alismatales) is a previously overlooked carnivorous lineage with a sticky-trap inflorescence. Field experiments, isotopic data and mixing models demonstrate significant N transfer from prey, with an estimated 68% of leaf N obtained from capture, comparable to levels for co-occurring sundew. Glandular hairs on flowering stems secrete phosphatase, a digestive enzyme seen in other carnivorous plants. Triantha is nearly unique among carnivorous plants in capturing prey on its inflorescence axis close to flowers; however, its glandular hairs capture only small insects. I also studied Triantha phylogeography across its mostly North American range, by surveying 11 plastid- encoded ndh genes from 75 populations. All three North American species are likely monophyletic, although T. occidentalis monophyly requires recognizing T. japonica as a synonym, which is consistent with its nested position in T. occidentalis, as the sister group of populations in Haida Gwaii (Canada). Plastid ndh genes have experienced various degrees of loss or reading frame interruption within T. glutinosa and T. occidentalis, and a strong geographic signal is evident in patterns of ndh gene loss/pseudogenization across the range of T. occidentalis. Short Bio: I’m now a postdoc in Prof. Sasa Stefanovic’s lab, University of Toronto Mississauga, and working on the genomic evolution of parasitic and mycoheterotrophic plants. I was born in China, and obtained a double degree for B.Sc. and B.A in Fudan University, Shanghai. I just got my Ph.D. degree in University of British Columbia this August. I’m interested in phylogeny and genomic evolution of land plants, especially heterotrophic and carnivorous plants. Research gate link: https://www.researchgate.net/profile/Qianshi_Lin .

Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

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.

Tracing History
Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911 Tracing History Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family BY ANNIKA VINNERSTEN ACTA UNIVERSITATIS UPSALIENSIS UPPSALA 2003 Dissertation presented at Uppsala University to be publicly examined in Lindahlsalen, EBC, Uppsala, Friday, December 12, 2003 at 10:00 for the degree of Doctor of Philosophy. The examination will be conducted in English. Abstract Vinnersten, A. 2003. Tracing History. Phylogenetic, Taxonomic and Biogeographic Research in the Colchicum Family. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911. 33 pp. Uppsala. ISBN 91-554-5814-9 This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. The molecular analysis based on three plastid regions—the rps16 intron, the atpB- rbcL intergenic spacer, and the trnL-F region—reveal the intrafamilial classification to be in need of revision. The two tribes Iphigenieae and Uvularieae are demonstrated to be paraphyletic. The well-known genus Colchicum is shown to be nested within Androcymbium, Onixotis constitutes a grade between Neodregea and Wurmbea, and Gloriosa is intermixed with species of Littonia. Two new tribes are described, Burchardieae and Tripladenieae, and the two tribes Colchiceae and Uvularieae are emended, leaving four tribes in the family. At generic level new combinations are made in Wurmbea and Gloriosa in order to render them monophyletic. The genus Androcymbium is paraphyletic in relation to Colchicum and the latter genus is therefore expanded.

The Evolution of Pollinator–Plant Interaction Types in the Araceae
BRIEF COMMUNICATION doi:10.1111/evo.12318 THE EVOLUTION OF POLLINATOR–PLANT INTERACTION TYPES IN THE ARACEAE Marion Chartier,1,2 Marc Gibernau,3 and Susanne S. Renner4 1Department of Structural and Functional Botany, University of Vienna, 1030 Vienna, Austria 2E-mail: [email protected] 3Centre National de Recherche Scientifique, Ecologie des Foretsˆ de Guyane, 97379 Kourou, France 4Department of Biology, University of Munich, 80638 Munich, Germany Received August 6, 2013 Accepted November 17, 2013 Most plant–pollinator interactions are mutualistic, involving rewards provided by flowers or inflorescences to pollinators. An- tagonistic plant–pollinator interactions, in which flowers offer no rewards, are rare and concentrated in a few families including Araceae. In the latter, they involve trapping of pollinators, which are released loaded with pollen but unrewarded. To understand the evolution of such systems, we compiled data on the pollinators and types of interactions, and coded 21 characters, including interaction type, pollinator order, and 19 floral traits. A phylogenetic framework comes from a matrix of plastid and new nuclear DNA sequences for 135 species from 119 genera (5342 nucleotides). The ancestral pollination interaction in Araceae was recon- structed as probably rewarding albeit with low confidence because information is available for only 56 of the 120–130 genera. Bayesian stochastic trait mapping showed that spadix zonation, presence of an appendix, and flower sexuality were correlated with pollination interaction type. In the Araceae, having unisexual flowers appears to have provided the morphological precon- dition for the evolution of traps. Compared with the frequency of shifts between deceptive and rewarding pollination systems in orchids, our results indicate less lability in the Araceae, probably because of morphologically and sexually more specialized inflorescences.

Nabalus Racemosus (Michx.) Hook. Glaucous White Lettuce
New England Plant Conservation Program Nabalus racemosus (Michx.) Hook. Glaucous white lettuce Conservation and Research Plan for New England Prepared by: Lisa St. Hilaire Ecologist 14 Prospect St. Augusta, Maine 04339 USA For: New England Wild Flower Society 180 Hemenway Road Framingham, Massachusetts 01701 USA 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, December 2003 1 SUMMARY Nabalus racemosus (Michx.) Hook., glaucous white lettuce, is a perennial member of the Asteraceae or composite family. It is considered globally secure (G5), but in New England, it is known only from northern Maine, primarily along the St. John River. There are also several occurrences along the Aroostook River. Ice scour and flooding are common annual disturbances on these rivers. Many of the N. racemosus populations were discovered during survey efforts for Pedicularis furbishiae (Furbish’s lousewort), and both species, as well as many other rarities, may be found at some sites. In other parts of the country, N. racemosus grows in prairie communities. There are currently 31 extant occurrences in Maine, 28 of these along the St. John River, and three on the Aroostook River. There are four historic occurrences, all on the Aroostook River, and one extirpated population on the Aroostook River. Nabalus racemosus is a species of Special Concern in Maine, where it is ranked S3. Other nearby areas from which it is recorded include New Brunswick (S3), Nova Scotia (S1), Newfoundland Island (S1S2), Labrador (SR), Quebec (SR), Vermont (SR), New Jersey (SH), New York (SX), and Pennsylvania (SX). Little is known regarding the biology of Nabalus racemosus.
