Coritico1, A. Fleischmann2 Key words Abstract Drosera rotundifolia, a species of the temperate Northern Hemisphere with a disjunct occurrence in high montane West Papua, has been discovered in a highland peat bog on Mt Limbawon, Pantaron Range, Bukidnon carnivorous plants on the island of Mindanao, Philippines, which mediates to the only other known tropical, Southern Hemisphere Drosera location in New Guinea and the closest known northern populations in southern Japan and south-eastern China. Droseraceae A dichotomous key to the seven Drosera species of the Philippines is given, and distribution maps are provided. Malesia Mindanao Published on 15 March 2016 Northern Hemisphere - Tropics disjunction Philippines INTRODUCTION Drosera rotundifolia L. (the generic type) is a temperate, winter dormant species that is widespread in the Northern The Philippines are rich in carnivorous plants, with about 47 Hemisphere, from Pacific North America across large parts of species known from the islands, most of which belong to the northern America and Europe to Siberia and the Kamchatka pitcher plant genus Nepenthes L. This genus has more than 30 Peninsula, South Korea and Japan. It is the Drosera spe- species in the Philippines, all except Nepenthes mirabilis (Lour.) cies covering the largest range, spanning the entire Northern Druce endemic to the country. Most species occur on Mindanao Hemisphere from 180° Western Longitude to about 180° East, and Palawan, while several are confined to a single highland however, not forming a continuous circumboreal range (Diels or even mountain peak (Robinson et al. -
Carnivorous Plant Newsletter V42 N3 September 2013
Technical Refereed Contribution Phylogeny and biogeography of the Sarraceniaceae JOHN BRITTNACHER • Ashland, Oregon • USA • [email protected] Keywords: History: Sarraceniaceae evolution The carnivorous plant family Sarraceniaceae in the order Ericales consists of three genera: Dar- lingtonia, Heliamphora, and Sarracenia. Darlingtonia is represented by one species that is found in northern California and western Oregon. The genus Heliamphora currently has 23 recognized species all of which are native to the Guiana Highlands primarily in Venezuela with some spillover across the borders into Brazil and Guyana. Sarracenia has 15 species and subspecies, all but one of which are located in the southeastern USA. The range of Sarracenia purpurea extends into the northern USA and Canada. Closely related families in the plant order Ericales include the Roridu- laceae consisting of two sticky-leaved carnivorous plant species, Actinidiaceae, the Chinese goose- berry family, Cyrillaceae, which includes the common wetland plant Cyrilla racemiflora, and the family Clethraceae, which also has wetland plants including Clethra alnifolia. The rather charismatic plants of the Sarraceniaceae have drawn attention since the mid 19th century from botanists trying to understand how they came into being, how the genera are related to each other, and how they came to have such disjunct distributions. Before the advent of DNA sequencing it was very difficult to determine their relationships. Macfarlane (1889, 1893) proposed a phylogeny of the Sarraceniaceae based on his judgment of the overlap in features of the adult pitchers and his assumption that Nepenthes is a member of the family (Fig. 1a). He based his phy- logeny on the idea that the pitchers are produced from the fusion of two to five leaflets. -

This page intentionally left blank Essential Orchids Orchids are one of the oldest and largest families in the plant kingdom with over 25,000 species worldwide. Through the millions of years of their existence, they developed complex relationships with their pollinators, animal communities, and environment in general. Today, orchids are now among the most widely grown and popular flowering potted plants in the world. With modern scientific cultivation, there are over 100,000 varieties of orchids and the number is increasing. However, in the wild populations are declining; many orchids are on the endangered lists, and almost all collecting of orchids is banned. What Makes an Orchid an Orchid? All orchids share three basic characteristics: ● Three sepals ● Three petals. In most orchids, one of these is highly modified and called a lip, or labellum. These are easy to see in most of the common orchids, and act as a landing pad for insect pollinators. ● A column. In most flowers the male (stamen) and female (pistil) reproductive structures are separate. -

ISSN: 1983-1471 – Online DOI: https://doi.org/10.18188/sap.v19i4.22193 TISSUE CULTURE APPLIED TO CARNIVOROUS SPECIES Mariana Maestracci Macedo Caldeira1, José Victor Maurício de Jesus1, Hemelyn Soares Magalhães1, Maria Antônia Santos de Carvalho1, Monielly Soares Andrade1, Claudineia Ferreira Nunes1* SAP 22193 Received: 17/04/2019 Accepted: 02/05/2020 Sci. Agrar. Parana., Marechal Cândido Rondon, v. 19, n. 4, oct./dec., p. 312-320, 2020 ABSTRACT - The purpose of the review is to comment on available data on the application of plant tissue culture to carnivorous plants. Thus, the review encompassed publications from 1979 to 2017 along in vitro germination studies and micropropagation techniques, such as somatic embryogenesis and organogenesis, which emphasized the responses of plant materials to the stimuli offered during in vitro culture. Tissue culture in carnivorous plants is presented as a tool to promote the increase of the population of these plants either for scientific and commercial purposes or for the conservation and reintroduction in their natural habitat, in order to ensure a sustainable exploitation of this nutritional pattern of plants. In general terms, the studies carried out were limited to the following aspects: cultivation technique, explant source, exogenously applied substances and culture medium. The review also revealed the absence of defined protocols for in vitro multiplication of large-scale carnivorous plants. Keywords: biotechnology, in vitro cultivation, insectivorous plants, micropropagation. CULTURA DE TECIDOS APLICADA A ESPÉCIES CARNÍVORAS RESUMO - O objetivo da revisão é comentar dados disponíveis sobre a aplicação da cultura de tecidos vegetais para plantas carnívoras. Assim, a revisão englobou publicações de 1979 a 2017 com estudos de germinação in vitro e técnicas de micropropagação, como embriogênese somática e organogênese, os quais enfatizam as respostas dos materiais vegetais aos estímulos oferecidos durante o cultivo in vitro. -

Phylogeny and Biogeography of South American Marsh Pitcher Plant Genus Heliamphora (Sarraceniaceae) Endemic to the Guiana Highlands Sukuan Liu and Stacey D. Smith Author for correspondence: Sukuan Liu, [email protected] Department of Ecology and Evolutionary Biology, University of Colorado Boulder, 1900 Pleasant Street, Boulder, Colorado 80309, U.S.A. Abstract: Heliamphora is a genus of carnivorous pitcher plants endemic to the Guiana Highlands with fragmented distributions. We presented a well resolved, time-calibrated, and nearly comprehensive Heliamphora phylogeny estimated using Bayesian inference and maximum likelihood based on nuclear genes (26S, ITS, and PHYC) and secondary calibration. We used stochastic mapping to infer ancestral states of morphological characters and ecological traits. Our ancestral state estimations revealed that the pitcher drainage structures characteristic of the genus transformed from a hole to a slit in single clade, while other features (scape pubescence and hammock-like growth) have been gained and lost multiple times. Habitat was similarly labile in Heliamphora, with multiple transitions from the ancestral highland habitats into the lowlands. Using Mantel test, we found closely related species tend to be geographically closely distributed. Placing our phylogeny in a historical context, major clades likely emerged through both vicariance and dispersal during Miocene with more recent diversification driven by vertical displacement during the Pleistocene glacial-interglacial thermal oscillations. -
5. Carnivorous Plants of Orono
CARNIVOROUS PLANTS OF ORONO BOG Fact sheet was created by Susan Priest, February 2012 and edited by Ronald B. Davis as an educational resource for Orono Bog Boardwalk. Some plants at Orono Bog have adapted to the low nutrient environment through carnivory. Carnivorous plants get extra nutrients by trapping and digesting small animals. There are four carnivorous plant species at Orono Bog: pitcher plant (Sarracenia purpurea), roundleaf sundew (Drosera rotundifolia), spoonleaf sundew (Drosera intermedia), and horned bladderwort (Utricularia cornuta). These plant species supplement their nutrient intake by breaking down insects, spiders, mites and micro- organisms. To trap prey each of these plants has developed specialized active or passive trapping systems. Pitcher plants and sundews use passive trapping methods, and bladderwort uses active trapping methods to catch prey (Johnson, 1985). To trap unsuspecting quarry the pitcher plant must first entice prey to land on the plant. The bright venation pattern and the fragrant scent emitted from leaf pores entice prey to the pitcher plant (Figure 1). Once at the plant the quarry will find a wide open lip for landing. If the quarry lands on the lip of the pitcher plant it will find that there are many tiny hairs that point down toward the rainwater filled basin in the cavity of the plant, which make it easier for prey to crawl downward, but difficult to climb out. Once in the hollow, the captured prey finds a sticky substance on the leaf wall, that makes climbing out of the basin impossible, and in the struggle to leave the trapped animal drowns (Johnson, 1985). -
Olfactory Prey Attraction in Drosera?
Technical Refereed Contribution Olfactory prey attraction in Drosera? Andreas Fleischmann • Botanische Staatssammlung München • Menzinger Strasse 67 • D-80638 Munich • Germany • [email protected] Keywords: trap scent, prey attraction, prey analysis, Lepidoptera, ecology, Drosera fragrans, Drosera finlaysoniana, Drosera slackii. The use of scented traps for prey attraction has been reported from a few genera of carnivorous plants: most prominently in the pitcher plant genera, where a sweet honey- or fruit-like scent is detectable to the human nose from the pitchers of some populations of Sarracenia flava, S. alata, S. rubra, S. oreophila, S. leucophylla, and S. minor (Miles et al. 1975; Slack 1979; Juniper et al. 1989; Jürgens et al. 2009; pers. obs.), certain species of Heliamphora (a sweet, honey-like scent is produced from the nectar-spoons of H. tatei, H. neblinae, and H. chimantensis, while the pitchers of H. sarracenioides produce a notable chocolate-like odor when growing under natural or favorable conditions; Fleischmann & McPherson 2010), and the pitchers of some species of Nepenthes (e.g. N. rafflesiana; Moran 1996; Di Giusto et al. 2008). Interestingly, the Venus Flytrap Dionaea also has been discovered to attract prey to its traps not only by the vivid coloration, but also by producing scented volatiles (Kreuzwieser et al. 2014). Furthermore, a weak, musty, fungus-like fragrance is emitted from the leaves of several Pinguicula species such as the five species from the southeastern United States (e.g. P. primuliflora and P. lutea, pers. obs.) and P. vallisneriifolia (Zamora 1995), and was even generalized to be true for the whole genus (Lloyd 1942; Slack 1979). -

Why Are Plants Carnivorous?
1 ECOPHYSIOLOGICAL LOOK AT PLANT CARNIVORY: Why are plants carnivorous? LUBOMÍR ADAMEC Institute of Botany, Section of Plant Ecology Dukelská 135, CZ-379 82 T řebo ň, Czech Republic 1. Introduction About 650 species of vascular carnivorous (Latin: carnis – flesh, vorare – to swallow) plants occur throughout the world (e.g., Rice, 2006) out of the total of about 300,000 species of vascular plants. Carnivorous plants belong to 15-18 genera of 8-9 botanical families and 5 orders (Givnish, 1989; Juniper et al., 1989; Müller et al., 2004; Heubl et al., 2006; Porembski and Barthlott, 2006; Studni čka, 2006). Due to many remarkable and striking morphological, anatomical, physiological, and ecological features, carnivorous plants have always attracted considerable interest of both researchers and gardeners. Nevertheless, the degree and extent of knowledge of the main disciplines studying this particular ecological functional plant group has always considerably lagged behind the study of non-carnivorous plants. However, similar to the dynamically growing knowledge of non-carnivorous plants, the study of carnivorous plants has developed very rapidly and progressively within the last decade, mainly due to the use of modern molecular taxonomic approaches. Also, modern ecophysiological research of carnivorous plants has progressed considerably within the last decade and has elucidated most of the particulars of carnivorous plants. Thus we are increasingly more able to discuss to what extent carnivorous plants are unique from or common with “normal” non-carnivorous plants. The aim of this paper is to classify and review recent experimental results and concepts concerning plant carnivory from an ecophysiological point of view, with an emphasis on mineral nutrition, growth characteristics, and comparison of aquatic and terrestrial carnivorous plants.
