Meholic All Rights Reserved ASSESSMENT OF THE HAMAMELIDACEAE IN GLOBAL LIVING COLLECTIONS by Catherine A. Meholic Approved: __________________________________________________________ John J. Frett, Ph.D. Professor in charge of thesis on behalf of the Advisory Committee Approved: __________________________________________________________ Erik Ervin, Ph.D. Chair of the Department of Plant and Soil Sciences Approved: __________________________________________________________ Mark W. Rieger, Ph.D. Dean of the College of Agriculture & Natural Resources Approved: __________________________________________________________ Douglas J. Doren, Ph.D. Interim Vice Provost for Graduate and Professional Education and Dean of the Graduate College ACKNOWLEDGEMENTS My sincerest thanks to Dr. John Frett for his patient guidance throughout this thesis process. I have had the privilege of his mentorship for the last decade, and without it this project would not have been possible. My thesis committee members are each owed my appreciation as well. Dr. Tara Trammell readily volunteered to be a part of the committee and has been generous with her time and guidance during this project. Anthony Aiello of the Morris Arboretum deserves thanks for his input in the project proposal and making multiple trips to the University. I appreciate all the time my committee has put into reviewing this dense and long thesis. It was a time- consuming task writing this thesis, and I understand it is also onerous to review it! Abbey Meyer of the Botanic Gardens Conservation International (BGCI) was instrumental in providing the data sets used in this research. Without this data this thesis would not have been possible. In addition, my sincerest appreciation to all the institutions that submitted data to BGCI (See Tables 68 for a full list of institutions that responded to the Collections Survey). It can be tedious to submit data annually and to each of the research requests, but it is invaluable in research such as this. Your efforts are appreciated. Finally, to my friends and family that have been neglected during this research, I am grateful for your continuous care and understanding. One cannot write a thesis on an empty stomach and you all have ensured that the writing continued uninterrupted! iii TABLE OF CONTENTS LIST OF TABLES ......................................................................................................... x LIST OF FIGURES ...................................................................................................... xv ABSTRACT ................................................................................................................ xvi Chapter 1 INTRODUCTION .............................................................................................. 1 1.1 Materials and Methods .............................................................................. 1 1.2 Family Description .................................................................................... 9 2 SPECIES DESCRIPTIONS ............................................................................. 14 2.1 Chunia Overview ..................................................................................... 14 2.1.1 Chunia bucklandioides H.T.

  • 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

  • Aeschynanthus Pulcher Lipstick Plant LIPSTICK PLANT
    The Gardener’s Resource 435 W. Glenside Ave. Since 1943 Glenside, PA 19038 215-887-7500 Aeschynanthus pulcher Lipstick Plant LIPSTICK PLANT Lipstick plants are easy indoor flowering houseplants that when given the right amount of light and water, they produce numerous red or orange small tubular flowers that resemble a tube of lipstick. Not only are the flowers colorful, the leaves can be light green, dark green or green and maroon. Light: The Lipstick vine will not bloom without adequate light. They require very bright, indirect light. Avoid placing this plant in full shade or full sun. Direct sun will burn the leaves. The plant needs bright light for a portion of the day, but not all day long. Water: If you allow the top 25% of the soil to dry out before watering, this plant will flower more frequently and more abundant. If the leaves appear soft and shriveled, give it more water. These plants will also lose green leaves TIPS: when over-watered. • Lipstick plants like warm temperatures between 75-85°F. : Fertilizer every other week in the Fertilizing • Prefers high humidity, but will do well in Spring and Summer and only monthly in the basic household humidity too. Fall and Winter with a houseplant food high in • Trim the long vines to prevent the plant phosphorous. Always dilute the fertilizer to ½ from becoming thin and straggly. the recommended strength. • Lipstick Plants are Non-Poisonous. • Keep a lipstick plant in a small pot will help it produce more flowers. When put into a large container, instead of producing flowers it grows more leaves.

A few of these were not happy in their location and promptly died, or did so poorly as to warrant their removal. A few new varie- ties were added to the original group, but for the most part these trees have been growing there s~nce the trial plot was first laid out. The collection has been of special interest to home owners in the suburban areas of Boston, who naturally are interested in small ornamental trees. It has also been of considerable interest to the tree wardens of various towns throughout New England, for here one may see many of the best small trees growing side by side, so that comparisons can be easily made. Recently this plot has been of interest to the Electric Council of New England, a group of utility companies which provide various electric services for the public in addition to stringing electric lines for these services. When the right kinds of trees are planted properly in the right places along the streets and highways, there need be but little competition between the trees and the wires.

  • Seeds of Woody Plants
    ARNOLDIA A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VOLUME 133 SEPTEMBER 11, 19533 NuMSERS 7-9 SEEDS OF WOODY PLANTS Collecting - Cleaning - Shipping - Longevity studies of seeds of plants, their collection, care and requirements for THEgermination, has been an intriguing one over the years. Much work has been done, mostly with the seeds of cereals, annuals and trees used for reforestation. Text books on forestry have much detailed information concerning forest tree seeds, but the seeds of many woody ornamental plants have not been studied as thoroughly as many a commercial grower would wish. This bulletin has to deal with such seeds, primarily with suggestions for their collection, care in storage, and shipping before they are sown. This information is taken from many sources. not the least of which are the first hand experiences here at the Arnold Arbore- tum where the propagators have been sowing such seeds for over 75 years. The best reference on the subject with an excellent bibliography, is "Woody Plant Seed Manual" written by the Forest Service, U.S. Department of Agriculture (Misc. Pub. No. 654, issued June 1948). Collecting Seeds should not be collected until they are ripe, for in many cases, seed col- lected prematurely may not germinate. Any collector who has had experience in this field knows that there are various methods of determining the ripeness of the fruit - the shrivelling of the pod or the cord connecting the seed to the pod in the legumes, the color or softness of the pulp of the fruit of Malus, Viburnum and Cotoneaster, and close examination of the cones of coniferous trees sometimes even tested by determining the specific gravity of the unopened cones.

  • Friends of Botanic Gardens Forum Newsletter Edition 4
    FRIENDS OF BOTANIC GARDENS FORUM NEWSLETTER EDITION 4 1 Dear Friends, The best time to plant a tree was 20 years ago. The second best time is now. (Chinese proverb) Well, here at last the 4th issue of the Friends of Botanic Gardens Forum. I have to first of all apologise for the delay in getting this out to you – but I suspect you are all doing as I have been doing these past few months – catching up with friends, family, holidays, your own gardens, considering future events – live or virtual over the forthcoming autumn/winter months and perhaps getting back to volunteering in the gardens/arboreta with whom you are associated. Next up I want to thank you all for your contributions – I have found it so interesting reading about the gardens and the activities of your groups and volunteers. The descriptions are tantalising and I look forward to visiting all of your spaces at some point in the not too distant future. You will note that a number of the gardens are celebrating significant anniversaries. We have already heard about the Royal Botanic Garden Edinburgh - 350 last year, and this year, Oxford Botanic Garden – 400, but we also have Dundee Botanic Garden celebrating 50 years. The project which the Friends at Dundee have supported will be a great asset to the garden and the Dundee community. It has been difficult to mark these occasions given the variable Covid restrictions. Any of you who have visited Edinburgh in the past might have seen the Floral Clock in Princes Street Gardens – last year, the RBGE was due to feature on the clock, but a decision was made to focus on the NHS in recognition of its extraordinary work during the Pandemic.
