Robinson to the highest peak of the Kemul Massif located a number of different Nepenthes taxa, including the type populations of N. fusca and N. mollis, neither of which have been observed in situ since they were first collected in 1925. Studies of the type form of N. fusca show that two further species should be considered, one largely restricted to Sabah’s Crocker range —here reinstated as N. zakriana— the second a southerly distributed species from Brunei, Sarawak and Kalimantan, named here as N. dactylifera.

  • Foraging Modes of Carnivorous Plants Aaron M
    Israel Journal of Ecology & Evolution, 2020 http://dx.doi.org/10.1163/22244662-20191066 Foraging modes of carnivorous plants Aaron M. Ellison* Harvard Forest, Harvard University, 324 North Main Street, Petersham, Massachusetts, 01366, USA Abstract Carnivorous plants are pure sit-and-wait predators: they remain rooted to a single location and depend on the abundance and movement of their prey to obtain nutrients required for growth and reproduction. Yet carnivorous plants exhibit phenotypically plastic responses to prey availability that parallel those of non-carnivorous plants to changes in light levels or soil-nutrient concentrations. The latter have been considered to be foraging behaviors, but the former have not. Here, I review aspects of foraging theory that can be profitably applied to carnivorous plants considered as sit-and-wait predators. A discussion of different strategies by which carnivorous plants attract, capture, kill, and digest prey, and subsequently acquire nutrients from them suggests that optimal foraging theory can be applied to carnivorous plants as easily as it has been applied to animals. Carnivorous plants can vary their production, placement, and types of traps; switch between capturing nutrients from leaf-derived traps and roots; temporarily activate traps in response to external cues; or cease trap production altogether. Future research on foraging strategies by carnivorous plants will yield new insights into the physiology and ecology of what Darwin called “the most wonderful plants in the world”. At the same time, inclusion of carnivorous plants into models of animal foraging behavior could lead to the development of a more general and taxonomically inclusive foraging theory.

  • Creation and Carnivory in the Pitcher Plants of Nepenthaceae and Sarraceniaceae
    OPEN ACCESS JCTS Article SERIES B Creation and Carnivory in the Pitcher Plants of Nepenthaceae and Sarraceniaceae R.W. Sanders and T.C. Wood Core Academy of Science, Dayton, TN Abstract The morphological adaptations of carnivorous plants and taxonomic distributions of those adaptations are reviewed, as are the conflicting classifications of the plants based on the adaptations, reproductive morphology, and DNA sequences. To begin developing a creationist understanding of the origin of plant carnivory, we here focus specifically on pitcher plants of Nepenthaceae and Sarraceniaceae because their popularity as cultivated curiosities has generated a literature resource amenable to baraminological analysis. Hybridization records were augmented by total nucleotide differences to assess species similarities. Nonhybridizing species falling within the molecular range of hybridizing species were included in the monobaramin of the hybridizing species. The combined data support each of the three genera of the Sarraceniaceae as a monobaramin, but the three could not be combined into a larger monobaramin. With the Nepenthaceae, the data unequivocally place 73% of the species in a single monobaramin, strongly suggesting the whole genus (and, thus, family) is a monobaramin. The lack of variation in the carnivorous habit provides no evidence for the intrabaraminic origin of carnivory from non-carnivorous plants. An array of fascinating symbiotic relationships of pitchers in some species with unusual bacteria, insects, and vertebrates are known and suggest the origin of carnivory from benign functions of the adaptive structures. However, these symbioses still do not account for the apparent complex design for carnivory characteristic of all species in the two families. Editor: J.W.

  • 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

  • Towards Resolving Lamiales Relationships
    Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales.

(Martyniaceae) is reported as a new alien species for the flora of Turkey. A plant species with different and interesting fruits was photographed in 2016. During a field investigation, a population of P. louisianica consisting of ca. 25 individuals was found at roadside between Biga and Karabiga town, district of Çanakkale, and plant specimens with flowers were collected in 2017. After detailed literature studies, this species was identified as Proboscidea louisianica. The family Martyniaceae is represented by just 1 genus with 1 taxa (Ibicella lutea (Lindl.) Van Eselt.) in Turkey and no member of the genus Proboscidea has been recorded before. In this paper, the species was introduced with taxonomical and morphological features. Its ecological impact was also evaluated with potential risks. Keywords: Proboscidea, Martyniaceae, new record, flora, Turkey Özet Bu çalışmada Proboscidea louisianica (Miller) Thell.

  • Carnivorous Plant Newsletter Vol 48, No 2, June 2019
    Byblis in cultivation in the tropics and in temperate climates Gregory Allan • Birmingham • United Kingdom • [email protected] Cindy Chiang • Singapore • [email protected] This article has been written based mostly on the authors’ experiences in growing Byblis in the UK and in Singapore. It is hoped that growers in regions with different climates will be able to extrapo- late from the information provided here, adjusting the methods described below to suit their own growing conditions. Hopefully much of the information provided here is universal in its application. Introduction If any genus of carnivorous plants deserves to be better known, both by horticulturalists and botanists, it is Byblis. The common name (ironically rarely used by enthusiasts) for the genus is “rainbow plants”, on account of the prismatic effect that can be produced when the sun shines on their copiously-produced sticky glands. All species follow a basic morphological plan: they have a central stem from which radiate numerous filiform leaves and scapes with showy flowers that typi- cally have purple petals (although white forms of most species are known) and vivid yellow anthers. Virtually all parts of the plants are covered in mucilage-tipped stalked glands (colloquially referred to as “tentacles”), which efficiently capture small insects, as well as microscopic sessile digestive glands. Another interesting characteristic of the genus is the presence of pulvini in most, if not all, species. Pulvini are swellings at the base of pedicels which, usually after successful pollination, uti- lize hydraulics to bend the pedicel, and consequently the developing fruit, downwards towards the ground. This phenomenon was discovered by Brian Barnes in the early 21st century.

  • The Cost of Carnivory for Darlingtonia Californica (Sarraceniaceae): Evidence from Relationships Among Leaf Traits1
    American Journal of Botany 92(7): 1085±1093. 2005. THE COST OF CARNIVORY FOR DARLINGTONIA CALIFORNICA (SARRACENIACEAE): EVIDENCE FROM RELATIONSHIPS AMONG LEAF TRAITS1 AARON M. ELLISON2,4 AND ELIZABETH J. FARNSWORTH3 2Harvard University, Harvard Forest, P.O. Box 68, Petersham, Massachusetts 01366 USA; and 3New England Wild Flower Society, 180 Hemenway Road, Framingham, Massachusetts 01701 USA Scaling relationships among photosynthetic rate, foliar nutrient concentration, and leaf mass per unit area (LMA) have been observed for a broad range of plants. Leaf traits of the carnivorous pitcher plant Darlingtonia californica, endemic to southern Oregon and northern California, USA, differ substantially from the predictions of these general scaling relationships; net photosynthetic rates of Darlingtonia are much lower than predicted by general scaling relationships given observed foliar nitrogen (N) and phosphorus (P) concentrations and LMA. At ®ve sites in the center of its range, leaf traits of Darlingtonia were strongly correlated with elevation and differed with soil calcium availability and bedrock type. The mean foliar N : P of 25.2 6 15.4 of Darlingtonia suggested that these plants were P-limited, although N concentration in the substrate also was extremely low and prey capture was uncommon. Foliar N : P stoichiometry and the observed deviation of Darlingtonia leaf traits from predictions of general scaling relationships permit an initial assessment of the ``cost of carnivory'' in this species. Carnivory in plants is thought to have evolved in response to N limitation, but for Darlingtonia, carnivory is an evolutionary last resort when both N and P are severely limiting and photosynthesis is greatly reduced. Key words: carnivorous plants; Darlingtonia californica; fens; leaf mass area; leaf traits; photosynthesis; nitrogen; serpentine.
