Stangeria Eriopus (Stangeriaceae): Medicinal Uses, Phytochemistry and Biological Activities
Alfred Maroyi /J. Pharm. Sci. & Res. Vol. 11(9), 2019, 3258-3263 Stangeria eriopus (Stangeriaceae): medicinal uses, phytochemistry and biological activities Alfred Maroyi Medicinal Plants and Economic Development (MPED) Research Centre, Department of Botany, University of Fort Hare, Private Bag X1314, Alice 5700, South Africa Abstract Stangeria eriopus is a perennial and evergreen cycad widely used as herbal medicine in South Africa. This study reviewed medicinal uses, phytochemistry and pharmacological properties of S. eriopus. Relevant information on the uses, phytochemistry and pharmacological properties of S. eriopus was collected from electronic scientific databases such as ScienceDirect, SciFinder, PubMed, Google Scholar, Medline, and SCOPUS. Pre-electronic literature search of conference papers, scientific articles, books, book chapters, dissertations and theses was carried out at the University library. Literature search revealed that S. eriopus is used as a protective charm against enemies, evil spirits, lightning, and bring good fortune or luck. The caudices, leaves, roots, seeds, stems and tubers of S. eriopus are used as emetics and purgatives, and as herbal medicine for body pains, congestion, headaches, high blood pressure and ethnoveterinary medicine. Phytochemical compounds identified from the species include alkaloids, amino acids, biflavones, fatty acids, glycosides, polyphenols, saponins and tannins. Pharmacological studies revealed that S. eriopus extracts have anti-hypertensive, anti-inflammatory and β-glycosidase -

We found 46 of the 358 described cycad species had at least one element reported to date. The only genus that was missing from the data was Microcycas. Many of the species reports contained concentrations of one to several macronutrients and no other elements. The cycad leaves contained greater nitrogen and phosphorus concentrations than the reported means for plants throughout the world. Magnesium was identified as the macronutrient that has been least studied. -

A low-maintenance plant has low fertilizer County for a list of recommended landscape plants requirements and few pest and disease problems. In suitable for south Florida. The resulting list includes addition, low-maintenance plants suitable for south over 350 low-maintenance plants. The following Florida must also be adapted to—or at least information is included for each species: common tolerate—our poor, alkaline, sand- or limestone-based name, scientific name, maximum size, growth rate soils. (vines only), light preference, salt tolerance, and other useful characteristics. An additional criterion for the plants on this list was that they are not listed as being invasive by the Criteria Florida Exotic Pest Plant Council (FLEPPC, 2001), or restricted by any federal, state, or local laws This section will describe the criteria by which (Burks, 2000). Miami-Dade County does have plants were selected. It is important to note, first, that restrictions for planting certain species within 500 even the most drought-tolerant plants require feet of native habitats they are known to invade watering during the establishment period. -

Anatomy of the Seedling of Bowenia Spectabilis, Hook. F
Anatomy of the Seedling of Bowenia spectabilis, Hook. f. BY H. H. W. PEARSON, B.A. 'Frank Smart' Student at GoimilU and Caius College, Cambridge, and Assistant Curator of the University Herbarium. With Plates XXVII and XXVm. HE genus Boweiiia was first described in the Botanical T Magazine in 1863, from plants sent to Kew from Rockingham Bay, in that year1. The particular interest of the plant from a phylogenetic point of view is centred in its bipinnate leaf, a character which is not found in other Cycads. ' With the exception of Stangeria paradoxa, no more remarkable Cycadaceous plant has been discovered than the subject of our present plate, and like that plant it differs from every other member of its Order in the nature of its leaves, which present remarkable analogies with those of Ferns; whereas, however, the anomalous character of Stangeria is affected by the venation of the pinnules, which so exactly simulated those of a Lomaria, that two authors had (unknown to one another) referred it to that genus, the resemblance in the case of Bowenia is in some respects 1 Curtis's Botanical Magazine, (3) VoU Jtix, Tab. 5398.

(OUV) of the Wet Tropics of Queensland World Heritage Area
Handout 2 Natural Heritage Criteria and the Attributes of Outstanding Universal Value (OUV) of the Wet Tropics of Queensland World Heritage Area The notes that follow were derived by deconstructing the original 1988 nomination document to identify the specific themes and attributes which have been recognised as contributing to the Outstanding Universal Value of the Wet Tropics. The notes also provide brief statements of justification for the specific examples provided in the nomination documentation. Steve Goosem, December 2012 Natural Heritage Criteria: (1) Outstanding examples representing the major stages in the earth’s evolutionary history Values: refers to the surviving taxa that are representative of eight ‘stages’ in the evolutionary history of the earth. Relict species and lineages are the elements of this World Heritage value. Attribute of OUV (a) The Age of the Pteridophytes Significance One of the most significant evolutionary events on this planet was the adaptation in the Palaeozoic Era of plants to life on the land. The earliest known (plant) forms were from the Silurian Period more than 400 million years ago. These were spore-producing plants which reached their greatest development 100 million years later during the Carboniferous Period. This stage of the earth’s evolutionary history, involving the proliferation of club mosses (lycopods) and ferns is commonly described as the Age of the Pteridophytes. The range of primitive relict genera representative of the major and most ancient evolutionary groups of pteridophytes occurring in the Wet Tropics is equalled only in the more extensive New Guinea rainforests that were once continuous with those of the listed area.
