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. -
UV Reflectance but No Evidence for Colour Mimicry in a Putative Brood-Deceptive Orchid Corybas Cheesemanii
Current Zoology 60 (1): 104–113, 2014 UV reflectance but no evidence for colour mimicry in a putative brood-deceptive orchid Corybas cheesemanii M. M. KELLY, A. C. GASKETT* School of Biological Sciences, The University of Auckland, Private Bag 92019, Auckland 1142, New Zealand Abstract Rewardless orchids attract pollinators by food, sexual, and brood-site mimicry, but other forms of sensory deception may also operate. Helmet orchids (Corybas, Nematoceras and related genera) are often assumed to be brood-site deceivers that mimic the colours and scents of mushrooms to fool female fungus gnats (Mycetophilidae) into attempting oviposition and polli- nating flowers. We sampled spectral reflectances and volatile odours of an endemic terrestrial New Zealand orchid Corybas cheesemanii, and co-occurring wild mushrooms. The orchid is scentless to humans and SPME GC-MS analyses did not detect any odours, but more sensitive methods may be required. The orchids reflected strongly across all visible wavelengths (300700nm) with peaks in the UV (~320nm), yellow-green (500600 nm) and red regions (650700 nm), whereas mushrooms and surrounding leaf litter reflected predominantly red and no UV. Rather than mimicking mushrooms, these orchids may attract pollinators by exploiting insects’ strong sensory bias for UV. Modelling spectral reflectances into a categorical fly vision model and a generic tetrachromat vision model provided very different results, but neither suggest any mimicry of mushrooms. However, these models require further assessment and data on fly spectral sensitivity to red wavelengths is lacking – a problem given the predominance of red, fly-pollinated flowers worldwide [Current Zoology 60 (1): 104113, 2014]. Keywords Diptera, Colour space, Fly pollination, Orchidaceae, Spectral reflectance, Visual modelling Flowers typically attract pollinators by advertising in the Orchidaceae, in which approximately one-third of rewards such as food (Chittka and Thompson, 2001; species do not reward their pollinators (Jersáková et al., Raguso, 2004). -

A total of 281 individuals were used to construct regional descriptions of D. kingianum and 139 individuals were measured for 19 morphological characters, and similarities and differences among specimens summarised using multivariate statistical methods. Patterns of morphological variation within D. kingianum are consistent with a single variable species that expresses clinal variation, with short-growing plants in the south and taller plants in the northern part of the distribution. The nrITS gene tree suggests two subgroups within D. kingianum subsp. kingianum, one comprising northern, the other southern individuals, which may overlap in the vicinity of Dorrigo, New South Wales.

Transnordestina s.n., 44036-900, Feira de Santana, Bahia, Brazil 3Fazenda Rio do Negro, Entre Rios, Bahia, Brazil Abstract The monospecific genus Discyphus, previously considered a member of Spiranthinae (Orchidoideae: Cranichideae), displays both vegetative and floral morphological peculiarities that are out of place in that subtribe. These include a single, sessile, cordate leaf that clasps the base of the inflorescence and lies flat on the substrate, petals that are long-decurrent on the column, labellum margins free from sides of the column and a column provided with two separate, cup-shaped stigmatic areas. Because of its morphological uniqueness, the phylogenetic relationships of Discyphus have been considered obscure. In this study, we analyse nucleotide sequences of plastid and nuclear DNA under maximum parsimony -

Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect.

Ackerman Tag der mündlichen Prüfung: 06.02.2004 Pleurothallis obliquipetala Acuña & Schweinf. Für Jakob und Julius, die nichts unversucht ließen, um das Zustandekommen dieser Arbeit zu verhindern. Zusammenfassung Die antillanische Flora ist eine der artenreichsten der Erde. Trotz jahrhundertelanger floristischer Forschung zeigen jüngere Studien, daß der Archipel noch immer weiße Flecken beherbergt. Das trifft besonders auf die Familie der Orchideen zu, deren letzte Bearbeitung für Cuba z.B. mehr als ein halbes Jahrhundert zurückliegt. Die vorliegende Arbeit basiert auf der lang ausstehenden Revision der Orchideengattung Pleurothallis R. Br. für die Flora de Cuba. Mittels weiterer morphologischer, palynologischer, molekulargenetischer, phytogeographischer und ökologischer Untersuchungen auch eines Florenteils der anderen Großen Antillen wird die Genese der antillanischen Pleurothallis-Flora rekonstruiert. Der Archipel umfaßt mehr als 70 Arten dieser Gattung, wobei die Zahlen auf den einzelnen Inseln sehr verschieden sind: Cuba besitzt 39, Jamaica 23, Hispaniola 40 und Puerto Rico 11 Spezies. Das Zentrum der Diversität liegt im montanen Dreieck Ost-Cuba – Jamaica – Hispaniola, einer Region, die 95 % der antillanischen Arten beherbergt, wovon 75% endemisch auf einer der Inseln sind. -

In nature, orchid seed germination is obligatory following infection by mycorrhizal fungi, which supplies the developing embryo with water, carbohydrates, vitamins, and minerals, causing the seeds to germinate relatively slowly and at a low germination rate. ,e nonsymbiotic germination of orchid seeds found in 1922 is applicable to in vitro propagation. ,e success of seed germination in vitro is influenced by supplementation with organic compounds. Here, we review the scientific literature in terms of the contents and role of organic supplements in promoting seed germination, protocorm development, and seedling growth in orchids. We systematically collected information from scientific literature databases including Scopus, Google Scholar, and ProQuest, as well as published books and conference proceedings. Various organic compounds, i.e., coconut water (CW), peptone (P), banana homogenate (BH), potato homogenate (PH), chitosan (CHT), tomato juice (TJ), and yeast extract (YE), can promote seed germination and growth and development of various orchids. -
