    Jacksonville Arboretum & Botanical Gardens Receives Grants to Start

    Jacksonville Arboretum & Botanical Gardens e-Newsletter February 2021 EDITION Hours: 8 a.m. to 5 p.m. Jacksonville Arboretum & Botanical Gardens Receives Grants to Start Master Plan Process Jacksonville, Fla. (Feb. 10, 2021) – Later this month, the Arboretum will begin the exciting process of developing a master plan to design and install botanical gardens on the property. The master plan process was made possible by generous grants of $30,000 from the Delores Barr Weaver Legacy Fund and $10,000 from the River Branch Foundation. The planning process will take about eight months to complete. The addition of botanical gardens is the latest in a continuous plan to propel the Arboretum into a best-in-class destination in the southeast. Executive Director Dana Doody noted that each project is being planned carefully to add as much value as possible while managing the non-profit’s budget plan in unprecedented times. In addition to the grant for the master plan design, the Delores Barr Weaver Legacy Fund also awarded the Arboretum a $70,000 challenge grant for the first phase of the implementation. The 1:1 challenge grant will launch a community campaign following the completion of the design plan. “The Arboretum is an important community asset which brings thousands of people to its special trails, many of which are ADA accessible,” said Delores Barr Weaver. “The plan will provide a vision for a botanical destination, sure to benefit our citizens for years to come.” The process will take into account the Arboretum’s unique qualities, Florida’s seasons and Jacksonville’s ecosystems and native horticulture.

M. & Sawady N.: Pollen Morphology of Malvaceae and its taxonomic signifi- cance in Yemen. — Fl. Medit. 18: 431-439. 2008. — ISSN 1120-4052. The pollen morphology of 20 species of Malvaceae growing in Yemen was investigated by light (LM) and scanning electron microscope (SEM). The studied taxa belong to 9 genera and three different tribes. These taxa are: Abelmoschus esculentus, Hibiscus trionum, H. micranthus, H. deflersii, H. palmatus, H. vitifolius, H. rosa-sinensis, H. ovalifolius, Gossypium hirsutum, Thespesia populnea (L.) Solander ex Correa and Senra incana (Cav.) DC. (Hibiscieae); Malva parviflora and Alcea rosea (Malveae); Abutilon fruticosum, A. figarianum, A. bidentatum, A. pannosum, Sida acuta, S. alba and S. ovata (Abutileae). Pollen shape, size, aperture, exine structure and sculpturing as well as the spine characters proved that they are of high taxonom- ic value. Pollen characters with some other morphological characters are discussed in the light of the recent classification of the family in Yemen. Key words: Malvaceae, Morphology, Yemen. Introduction Malvaceae Juss. (s. str.) is a large family of herbs, shrubs and trees; comprising about 110 genera and 2000 species. It is a globally distributed family with primary concentrations of genera in the tropical and subtropical regions (Hutchinson 1967; Fryxell 1975, 1988 & 1998; Heywood 1993; La Duke & Doeby 1995; Mabberley 1997). Due to the high economic value of many taxa of Malvaceae (Gossypium, Hibiscus, Abelmoschus and Malva), several studies of different perspective have been carried out, such as those are: Edlin (1935), Bates and Blanchard (1970), Krebs (1994a, 1994b), Ray (1995 & 1998), Hosni and Araffa (1999), El Naggar (1996, 2001 & 2004), Pefell & al.

    Hollyhock Rust Caroline Jackson and Josephine Mgbechi-Ezeri

    Sample of the week: Hollyhock rust Caroline Jackson and Josephine Mgbechi-Ezeri Have strange orange and brown bumps plagued your flower beds this year? The prolonged cool temperatures and heavy precipitation this spring have allowed fungal pathogens to flourish. Here is one heavy infestation of Hollyhock rust, a disease that is caused by the fungal pathogen Puccinia malvacearum. Common hosts include Alcea rosea, (hollyhock), Abutilon spp. (flowering maple), Malvaceae spp. (rose mallow), Figure 1. Yellow spots on upper leaf surface Photo Credit: and common weed mallow. It is Caroline Jackson, University of Missouri Plant Diagnostic Clinic one of the most common diseases of hollyhock. Symptoms of the disease include the yellow to red spots on upper leaf surface, and brown pustules that appear blister-like occur on lower leaf surface and stem. Leaves that are heavily infected often wilt, turn brown and die. This disease is the most common of hollyhock and can spread rapidly from leaf to leaf. The fungus overwinters in the infected plant materials, and in the spring produce spores that are dispersed by wind to initiate infection on new plants. Figure 2. Orange brown pustules on underside of leaf Photo Credit: Caroline Jackson, University of Missouri Plant Diagnostic Clinic For appropriate diagnosis, the MU Plant Diagnostic Clinic can help you confirm if your plant has this disease.

The leaf samples of the hollyhock were taken from the roadside areas affected by heavy metal pollution due to intensive motorized traffic and from areas 30 m from the roadside by taking into account prevailing wind direction in 10 different locations. There were only significant differences for Mn, Cu, and Zn contents of leaves according to the sampling locations. The mean Fe (383.3 mg kg-1), Mn (50.2 mg kg-1), Cu (19.2 mg kg-1), Zn (23.9 mg kg-1), Cd (17.9 mg kg-1), Cr (5.1 mg kg-1), Ni (3.2 mg kg-1), and Pb (3.2 mg kg-1) contents of leaves sampled from roadside areas were significantly higher than mean heavy metal contents of leaves sampled from the areas 30 m from the roadside. The increasing ratios in mean heavy metal contents of leaves were ordered as Cd (309.3%) > Cr (248.9%) > Ni (130.6%) > Fe (75.9%) > Pb (64.3%) > Mn (40.6%) > Cu (26.1%) > Zn (22.7%).

    HOLLYHOCK-PINK Alcea Rosea Characteristics Culture Noteworthy

    HOLLYHOCK-PINK Alcea rosea Characteristics Type: Perennial Water: Medium Zone: 2 to 10 Maintenance: High Height: 6.00 to 8.00 feet Suggested Use: Annual, Naturalize Spread: 1.00 to 2.00 feet Flower: Showy Bloom Time: June to August Attracts: Hummingbirds, Butterflies Bloom Description: White, pink, & red Tolerate: Rabbit, Black Walnut Sun: Full sun Culture Grow in average, medium moisture, well-drained soil in full sun. Tolerates a wide range of soil conditions and some light shade, but will not tolerate wet winter soils. Considered a biennial or short-lived perennial. If grown from seed, plant seeds in August or September for bloom the following year. Although short- lived, hollyhocks easily self-seed and can establish colonies in the garden that persist for years as if they were perennials. Noteworthy Characteristics Alcea rosea, commonly called hollyhocks, are old garden favorites. The flowers grow on rigid, towering spikes or spires which typically reach a height of 5-8' tall and usually do not require staking. Foliage features large, heart-shaped (3, 5 or 7 lobes), rough lower leaves which become progressively smaller toward the top of the spire. Long bloom period of June to August. Sometimes listed in nursery catalogs under Althaea. This is a mix of plants which produce huge (4-5" diameter), outward-facing, single flowers in a wide variety of colors including reds, pinks, whites, and light yellows. Problems Foliage is susceptible to rust, leaf spot and anthracnose. Spider mites and Japanese beetle can also be problems. Foliage can become rather tattered and unkempt in appearance when attacked by the aforementioned insects and/or diseases, but the flowers generally are not affected.
  • 77 CHAPTER 5 REPRODUCTION on the CLIFF Obligate Cremnophytes

    77 CHAPTER 5 REPRODUCTION on the CLIFF Obligate Cremnophytes

    CHAPTER 5 REPRODUCTION ON THE CLIFF Obligate cremnophytes are exiled to life on a cliff and are effectively adapted to their vertical habitat where there is no (or limited) disturbance by larger mammals. Very few plants other than succulents can sustain life on a cliff, and the few non-succulent species that do survive, display a shift in reproductive strategy. Obligate cremnophytes cannot compete in conventional (non- cliff) accessible habitats and even if they do germinate in a non-cliff situation, the plants will soon be grazed. All plants are dependent on moisture, nutrients and sufficient solar radiation and cremnophytes have to cope with gravity in special ways. Furthermore, sustained life on a cliff demands an effective reproductive strategy. The overall reproductive behaviour of obligate cremnophytes deviates from that of their non-cremnophilous relatives in accessible habitats. The emphasis in this chapter is on cliff-adapted reproductive strategies. Apart from their sexual reproduction, most (204 or 93% of the taxa studied) obligate succulent cremnophytes have an in situ vegetative propagation backup. There is therefore a clear shift to vegetative propagation on the cliff and many cremnophytes are dependent on this asexual mode of reproduction. Both sexual and asexual reproduction are discussed below. Semisucculent plants such as Dewinteria petrophila [221], Stemodiopsis rivae [222] and Colpias mollis are less succulent but have additional strategies such as active cremnocarpy and cremno-amphicarpy. Colpias mollis and D. petrophila are almost ephemeral or weak perennials. The vertical habitat and the constant presence of gravity demand an effective seed dispersal strategy. Cliffs are known for updrafts and birds of prey are often observed as they glide on thermals above cliff faces.
