Planting a Dry Rock Garden in Miam1
Succulents in Miam i-D ade: Planting a D ry Rock Garden John McLaughlin1 Introduction The aim of this publication is twofold: to promote the use of succulent and semi-succulent plants in Miami-Dade landscapes, and the construction of a modified rock garden (dry rock garden) as a means of achieving this goal. Plants that have evolved tactics for surviving in areas of low rainfall are collectively known as xerophytes. Succulents are probably the best known of such plants, all of them having in common tissues adapted to storing/conserving water (swollen stems, thickened roots, or fleshy and waxy/hairy leaves). Many succulent plants have evolved metabolic pathways that serve to reduce water loss. Whereas most plants release carbon dioxide (CO2) at night (produced as an end product of respiration), many succulents chemically ‘fix’ CO2 in the form of malic acid. During daylight this fixed CO2 is used to form carbohydrates through photosynthesis. This reduces the need for external (free) CO2, enabling the plant to close specialized pores (stomata) that control gas exchange. With the stomata closed water loss due to transpiration is greatly reduced. Crassulacean acid metabolism (CAM), as this metabolic sequence is known, is not as productive as normal plant metabolism and is one reason many succulents are slow growing. Apart from cacti there are thirty to forty other plant families that contain succulents, with those of most horticultural interest being found in the Agavaceae, Asphodelaceae (= Aloacaeae), Apocynaceae (now including asclepids), Aizoaceae, Crassulaceae, Euphorbiaceae and scattered in other families such as the Passifloraceae, Pedaliaceae, Bromeliaceae and Liliaceae. -

Pyrrosia schimperiana (Mett. ex Kuhn) Alston PYRROSIA Mirb. 1. Pyrrosia schimperiana (Mett. ex Kuhn) Alston in Journal of Botany, London 72, Suppl. 2: 8 (1934). Cremnophyte growth form: Cluster-forming, subpendulous leaves (of medium weight, cliff hugger). Growth form formula: A:S:Lper:Lc:Ts (p) Etymology: After Wilhelm Schimper (1804–1878), plant collector in northern Africa and Arabia. DESCRIPTION AND HABITAT Cluster-forming semipoikilohydric plant, with creeping rhizome 2 mm in diameter; rhizome scales up to 6 mm long, dense, ovate-cucullate to lanceolate-acuminate, entire. Fronds ascending-spreading, becoming pendent, 150–300 × 17–35 mm, succulent-coriaceous, closely spaced to ascending, often becoming drooping (2–6 mm apart); stipe tomentose (silvery grey to golden hairs), becoming glabrous with age. Lamina linear-lanceolate to linear-obovate, rarely with 1 or 2 lobes; margin entire; adaxial surface tomentose becoming glabrous, abaxial surface remaining densely tomentose (grey to golden stellate hairs); base cuneate; apex acute. Sori rusty brown dots, 1 mm in diameter, evenly spaced (1–2 mm apart) in distal two thirds on abaxial surface, emerging through dense indumentum. Phenology: Sori produced mainly in summer and spring. Spores dispersed by wind, coinciding with the rainy season. Habitat and aspect: Sheer south-facing cliffs and rocky embankments, among lichens and other succulent flora. Plants are scattered, firmly rooted in crevices and on ledges. The average daily maximum temperature is about 26ºC for summer and 14ºC for winter. Rainfall is experienced mainly in summer, 1000–1250 mm per annum. -
CHAPTER 1 INTRODUCTION 1.1 Objectives, Key Questions and Hypotheses the Flora of Cliffs Is One of the Least Studied Biotic Assem
CHAPTER 1 INTRODUCTION 1.1 Objectives, key questions and hypotheses The flora of cliffs is one of the least studied biotic assemblages in the world. Most of these plants are uniquely adapted to this type of habitat and are known as cremnophytes (from the Greek, kremnos = cliff + phyton = plant). In southern Africa, here defined as South Africa and Namibia, these vertical rock faces are the habitat of many succulent plants. This study is the first in the world to focus only on these obligate cremnophytes, and in particular those that are essentially succulents and bulbous succulents. The principal aims of this study were to: Describe and document all the obligate or near-obligate succulent plants (and their bulbous component) growing on cliff faces throughout South Africa and Namibia. Describe and interpret the morphological adaptations of succulent cremnophytes to the cliff-face habitat, both vegetatively and in terms of sexual reproduction. The key questions to be asked, included: How many obligate or near-obligate succulent cremnophytes occur in southern Africa and what are their identities? What are the adaptive traits of succulent cremnophytes distinguishing them from related plants from non-cliff habitats? What is the influence of geology and climate on the geographical distribution of succulent cremnophytes? What is the conservation status of succulent cremnophytes? 1 Obligate cremnophilous succulent plant species grow in the absence of larger herbivores. The vertical habitat furthermore demands a shift in strategy with regard to plant morphology and reproductive behaviour. How do cremnophytes survive in a hyper-arid terrain (high water run-off) and in the absence of larger herbivores? This study focuses on the macro-morphological and reproductive adaptations of obligate cremnophilous succulents that enable their self-sustaining long-term survival on the cliffs. -

Cape Plants: Corrections and Additions to the Flora
19 May, 2008 Cape flora additions 1 CAPE PLANTS: CORRECTIONS AND ADDITIONS TO THE FLORA P. GOLDBLATT*, J.C. MANNING** & D. SNIJMAN** *B. A. Krukoff Curator of African Botany, Missouri Botanical Garden, P. O. Box 299, St. Louis, Missouri 63166, U.S.A. [email protected] **Compton Herbarium, National Botanical Institute, Private Bag. X7, Claremont 7735, South Africa [email protected] MS. Received: Keywords: Cape Floristic Region, floristics, phytogeography, plant diversity, southern Africa, speciation Abstract Comprising an area of ± 90,000 km 2, less than 5% of the land surface of the southern African subcontinent, the Cape Floristic Region (CFR) is one of the world‘s richest areas for plant species diversity. A recent synoptic flora for the Region has established a new base line for an accurate assessment of the flora. Here we document corrections and additions to the flora at family, genus and species ranks. As treated in Cape Plants , which was completed in 1999, the flora comprised 173 families (5 endemic), 988 genera (160 endemic: 16.2%), and 9 004 species (6192 endemic: 68.8%). Just four years later, a revised count resulting from changes in the circumscriptions of families and genera, and the discovery of new species or range extensions of species, yields an estimate of 172 families (4 endemic), 992 genera (162 endemic: 16.3%) and 9 087 species (6 226: 68.5% endemic). Of these, 947 genera and 8 971 species are flowering plants. The number of species packed into so small an area is remarkable for the temperate zone and compares favourably with species richness for areas of comparable size in the wet tropics. -

HERBS & FLOWERS ALOE Aloe Aloe barbadensis TP 1’ Aloe leaves are used to treat burns and rash. Aloe vera is a perennial plant with yellow flowers and it’s tough, fleshy, spear like leaves can grow up to 20” long. Only the leaves are used for medicine. The clear, thick gel found in the inner part of the leaf is commonly used for minor cuts and burns. Anise Hyssop BASIL Basil Downy Mildew You may not hear a lot about the following disease from other sources but we want you to know about it and what to do. We are Aloe bringing the awareness of this disease to all of our customers. Basil Downy Mildew (Pernospora belbahrii) Basil Downy Mildew is a new disease to North America and AMARANTHUS Europe. It was first reported in Europe in 2001 and was identified in the United States in October 2007. It is now nearly in every Amaranth, Pygmy Torch state including Minnesota. Amaranthus hypochondriacus A 2’ Description of downy mildew The pathogen (Peronospora belbahrii) is a water-mold (oomycete) Amaranthus grows in clumps producing showy foliage with that can be spread by contaminated seed, by infected basil leaves dark-green to purple leaves and upright spikes of burgundy-red and as wind-dispersed spores. Spores of the pathogen are capable flowers. Good choice to grow in containers. Shiny black seeds of being dispersed long distances. Infected basil leaves produce an are edible. abundance of spores. Thus the pathogen can spread widely once introduced to an area. The optimum environmental conditions for disease development occur at high humidity. -

RORAIMA NURSERY Newsletter No. 2 20 Swan Street Lara Vic 3212 Summer 2011 Ph: 03 5282 8704 Email: [email protected] Website: www.roraimanursery.com.au The Staff and Management at Roraima Nursery Would like to wish all our customers a Very Merry Christmas and a Happy New Year in 2012 Christmas Trading Days: The Nursery will be closed on Christmas Day, Boxing Day, and New Year’s Day. We will be trading as normal from 9am till 5pm all other days. SUMMER GARDENING Summer is now upon us. It is a very picturesque time of the year and wonderful to see so many cacti and succulents in full flower. Cacti have been flowering since October and are still opening up their impressive blooms that make Summer so enjoyable. Each day in the garden a new variety exhibits their finely detailed flowers. We have large quantities of unnamed cacti and succulents available at the Nursery for very low prices. 5cm pots are just $2.50ea, or 5 for $10; 10cm pots are $3.50ea or 5 for $15. There is so much to do in the garden before the heat in January/February arrives! Ensure that sufficient mulch is around all plants – approx. 10cm think for best results - and apply water saving liquid/crystals where necessary to help the plants cope with the heat of Summer. It is an excellent way to assist your plants with good health through the hot months. It is important to check moisture levels in soil over Summer. Grouping plants with similar water requirements is an added advantage and saves time in testing soil moisture levels in so many locations. -
Retallack and Landing 2014 Prototaxites Supplements
Data Supplements “Affinities and architecture of Devonian trunks of Prototaxites loganii” 1 2 Gregory J. Retallack , Ed Landing 1Department of Geological Sciences, University of Oregon, Eugene, 97403, Oregon, USA: 2Department of Earth and Environmental Sciences, Lamont-Doherty Earth Observatory of Columbia University, Palisades, New York, USA, 10964 Notes S1 Evidence against algal affinities Schweitzer (1983) reconstructed compressions of “Prototaxites cf. P. logani” (here regarded as Mosellophyton hefteri) as a kelp-like alga of deep river channels and oxbow lakes, and was especially impressed by the thin flexuous branches of that species. However, the bases of M. hefteri trunks are very stout (Schaarschmidt 1974), and its overall proportions comparable with Prototaxites loganii and terrestrial vascular land plants (Fig. S4). Kelp has very different proportions with hollow flexuous stems narrowed near the base and capable of bending with unusually strong waves and currents (Koehl and Wainright 1977). The histology of Prototaxites loganii with three distinct size-classes of tubular cells, investing and surrounding clusters of small coccoid cells (Figs. 4-5) is unlike any histology known in fossil algae. The tubular cells of Prototaxites rarely taper or dichotomize like filaments of green algae (Retallack 1983). Nor do tubular cells of Prototaxites resemble equant parenchymatous cells of red and brown algae (Koehl and Wainright, 1977; Taylor et al. 2009). Like the New York Schunnemunk tree, Prototaxites loganii in Quebec is found mainly in fluvial paleochannels, distinct from plant assemblages of trimerophytes and zosterophylls associated with weakly developed gleyed paleosols (Griffing et al. 2000; Hotton et al. 2001). Nevertheless, vertical inclusions of other vascular land plants are common within permineralized Prototaxites from Quebec and Australia, as if it overgrew nearby vascular land plants (Hueber 2001). -
CACTUS ISLAND AFRICA - AMERICA - MADAGASCAR AFRICA’S CACTUS ISLAND the Genus Aeonium Spp
CACTUS ISLAND AFRICA - AMERICA - MADAGASCAR AFRICA’S CACTUS ISLAND The genus Aeonium spp. It is mainly known for a specific species, Aeonium arboreum. It is the species that is most cultivated from the ornamental vision of the plant. Still, this genus consists of almost 100 species, of which just under half are indigenous to the Canary Islands. Of course, we can consider the genus Aeonium as ours. It can be found throughout the Mediterranean basin and island areas such as Sardinia or Sicily and even in areas such as Morocco or East Africa. It has a bushy bearing with branched stems and with the formation of dense rosettes AEONIUM ARBOREUM composed of fleshy leaves, a characteristic that identifies succulent plants. Depending on the species and the variety, the color variations in its leaves range from green to almost black and bright satin purple with a special appeal. Some varieties of the genus such as Aeonium arboreum can measure up to 1 meter or even more and their very long inflorescences with yellow flowers are very characteristic. It is striking and of an unmatched contrast, the yellow inflorescences with the purple rosettes. An additional advantage of this plant is that the flowers last a long time on the plant, providing added aesthetic value. In some varieties, when sun grown outdoors, the direct incidence of the sun causes an accentuation of the purple hues achieving a gradient from green to purples from the heart of the rosette to the tip of the leaf of high ornamental value (main photo) . AEONIUM ATROPURPUREUM Single stem species, with leaves arranged in a rosette between 0.60 to 1 meter high and 30 cm (- 100) wide.
