On Tropical Drosera Rotundifolia L
Technical Refereed Contribution On tropical Drosera rotundifolia L. Andreas Fleischmann • Botanische Staatssammlung München and GeoBio-Center LMU University • Menzinger Strasse 67 • D-80638 Munich • Germany • [email protected] Abstract: Two aspects on the morphology and biology of the Philippine population of D. rotundifo- lia were not answered by Coritico and Fleischmann (2016), namely its seed morphology and sea- sonal growth cycle - especially regarding hibernaculum formation, as it is known from its temperate congeners. These gaps can now be covered from observations made from cultivated plants and shall be reported here. Further aspects on the biology of Philippine D. rotundifolia (and other tropical populations of temperate Drosera) in cultivation and natural habitat are presented. Distribution and altitudinal range of Drosera rotundifolia The generic type species of Drosera, Drosera rotundifolia L., is probably the most well-known sundew species, at least to people from the Northern Hemisphere. It is also the most widespread1, its range spans the entire boreal region (Fig. 1; Meusel et al. 1965). Its southernmost populations in the Northern Hemisphere are situated in SE China, in the mountain ranges of northern Guangdong province, at ca. 24.5°N (Coritico & Fleischmann 2016). In Europe its more or less continuous range reaches to ca. 39°N to the south in central Spain, in North America to ca. 34°N in northern Georgia and Alabama states, in Japan to 30°N on the island of Yakushima (Coritico & Fleischmann 2016). Additionally, D. rotundifolia shows a few isolated outlier populations in some areas of the Mediter- ranean [e.g. on the isle of Corsica, France (Delange & Hugot 2020), in the Sierra Nevada of southern Spain (Lorite 2016), and in northern Greece (just three sites known in the Rhodope Mountains; The- odoropoulos & Eleftheriadou 2012)], in central Lebanon (Diels 1906; Tohmé & Tohmé 2007; despite erroneous claims, e.g. -

CATALOGUE of the GRASSES of CUBA by A. S. Hitchcock
CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. -

1/22 Hygroscopic Awns of Two Prairie Grasses, Andropogon Gerardii And
1/22 Hygroscopic awns of two prairie grasses, Andropogon gerardii and Sorghastrum nutans A THESIS SUBMITTED TO THE FACULTY OF THE PROGRAM IN PLANT BIOLOGY AND CONSERVATION BY JOSHUA MICHAEL DRIZIN IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN PLANT BIOLOGY AND CONSERVATION FROM NORTHWESTERN UNIVERSITY AND THE CHICAGO BOTANIC GARDEN May 16, 2013 2/22 3/22 Abstract The prairie grasses Andropogon gerardii and Sorghastrum nutans have seeds with awns that twist in response to changes in humidity. The humidity-sensitive, or hygroscopic, part of the awn twists, moving the bent, passive portion in an arc. This trait has been demonstrated to improve seedling recruitment in other grass species by dispersing the seeds to superior microsites. Hygroscopicity was defined as the time taken for the awn to complete one rotation. The goals were to 1. estimate heritability of hygroscopicity, 2. assess population-level differences in hygroscopicity, and 3. examine the relationship between hygroscopicity and seed movement. Two sets of seed were used. Seeds were collected in west-central Minnesota from individual maternal plants in remnant and restoration populations and were grown out to collect a second seed generation, used to assess heritability. To assess population differences and unidirectional movement, seeds were purchased from conservation seed suppliers from across the species' range. Time-lapse photography and humidity manipulation were used to characterize seed movement. I found a weak trend of heritability in Andropogon but not Sorghastrum. Northern populations of Sorghastrum spun more slowly than those of southern populations. There was no difference in rotation time among Andropogon populations. -
Carnivorous Plant Newsletter Vol 48 No 4 December 2019
Drosera in the western USA—an update Barry A. Rice • Center for Plant Diversity • University of California • One Shields Avenue • Davis • California 95616 • USA • [email protected] Keywords: Taxonomy: Drosera, western USA, Drosera anglica, Drosera intermedia, Drosera linearis, Drosera × obovata, Drosera rotundifolia, Drosera × woodii. One of my primary research activities focuses on carnivorous plants in the US states of Montana, Wyoming, Colorado, New Mexico, and westward (but excluding Alaska). Throughout most of this range, the only native species of Drosera are Drosera rotundifolia L., Drosera anglica Huds., and the hybrid Drosera × obovata Mert. & Koch. These species are well-known to readers of this jour- nal, and need no further description. In this region, these plants quite often occur in sites that are widely separated, and in some states these taxa are of considerable rarity (for example, in Colorado D. rotundifolia and D. anglica are known at only 4 and 1 sites, respectively; Wolf et al. 2006). In addition to these species, there have been reports of two additional native Drosera—Drosera intermedia Hayne in northern Idaho (and perhaps adjacent eastern Washington), and Drosera lin- earis Goldie in Montana. Drosera intermedia was reported in Boundary County, Idaho by Bursik (1993), as growing with Drosera anglica, but being quite different in form. Additional populations were subsequently found in Custer County, Idaho (L. Kinter, pers. comm. 2017). Of course, the closest other Drosera inter- media plants were on the other side of the continent, so this was considered a find of great interest, and the plants were treated as of special significance. A few years ago, I decided I needed to visit and assess these plants. -
Drosera Intermedia in a Northern Michigan Bog
Assessment of microhabitat differences between Drosera rotundifolia and Drosera intermedia in a northern Michigan bog Andrew David University of Michigan Biological Station EEB 381, General Ecology August 19, 2010 Professor Cathy Bach Abstract The purpose of this study was to investigate microhabitat differences between two species of sundews, Drosera rotundifolia and Drosera intermedia. I tested several hypotheses: D. rotundifolia density increases with increasing height above a fixed low point, while D. intermedia density decreases with height; D. rotundifolia grows primarily on red Sphagnum moss, while D. intermedia grows primarily on green Sphagnum; the densities of both Drosera species increase with decreasing pH; the density of neither Drosera species is affected by water conductivity or dissolved oxygen content. At Mud Lake Bog in Cheboygan County, Michigan, I recorded the species of Drosera plants, as well as the height of the plants above a fixed low point and the color of Sphagnum moss on which they were growing. I also measured the pH, conductivity, and dissolved oxygen content of the water in which the plants were growing. Densities of both Drosera species decreased with increasing height, though the trend was stronger for D. intermedia. D. rotundifolia grew significantly more on red Sphagnum than did D. intermedia, while D. intermedia grew significantly more on green Sphagnum than did D. rotundifolia. D. rotundifolia density varied significantly with neither pH, conductivity, nor dissolved oxygen. D. intermedia density increased significantly with decreasing pH and increasing conductivity, but not with dissolved oxygen. My results were consistent with past research, and conclusively illustrated the differences in microhabitat preferences between the two Drosera species. -
DROSERA ROTUNDIFOLIA DIET DETERMINATION USING DNA DATA by 1,2 2 2,3 BARBORA LEKESYTE , STEPHEN KETT and MARTIJN J.T.N
Journal of the Lundy Field Society, 6, 2018 WHAT’S ON THE MENU: DROSERA ROTUNDIFOLIA DIET DETERMINATION USING DNA DATA by 1,2 2 2,3 BARBORA LEKESYTE , STEPHEN KETT AND MARTIJN J.T.N. TIMMERMANS 2Department of Natural Sciences, Middlesex University, The Burroughs, Hendon, London, NW4 4BT 3Department of Life Science, Natural History Museum, Cromwell Road, London, SW7 5BD 1Corresponding author, e-mail: [email protected] ABSTRACT The round-leaved sundew, Drosera rotundifolia, is a carnivorous plant species. On Lundy it is found in the nutrient-poor bog environments of Pondsbury and the northernmost quarry, where it supplements its diet with invertebrate prey. To gain insight into the diet of these two sundew populations a metabarcoding approach was trialled. This is, to our knowledge, the first study to use DNA barcodes to identify Drosera prey. At each site, a 0.25m2 quadrat was placed in a representative Drosera patch and two days’ worth of prey were collected. To identify prey items, Cytochrome c oxidase subunit I (COX1) sequences were obtained and compared to the Barcode of Life database. This revealed that Lundy sundews have a mixed diet. In total at least 20 different prey taxa were detected in the two 0.25m2 areas sampled. Sixteen taxa could be identified to species, indicating that metabarcoding permits accurate species level identification of sundew prey items. The majority of prey taxa were dipterans (two-winged flies), of which several have previously been reported on Lundy. Most prey taxa were detected in only one of the two quadrats examined (Jaccard’s index of Similarity=0.01; ‘dissimilar’). -
