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. -

The four Ceratozamia species and S. eriopus showed the same chromosome number of 2n = 16, and had similar karyotypes, comprising 12 metacentric (m), two submetacentric (sm) chromosomes and two telocentric (t) chromosomes. The four Ceratozamia species exhibited a proximal 5S rDNA site in the interstitial region of two m chromosomes. Stangeria eriopus exhibited a distal 5S rDNA site in the interstitial region of two m chromosomes, which probably indicates that the two genera differ in chromosome structure by at least one paracentric inversion. © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society, 2004, 145, 499–504.

Species Encephalartos Family Zamiaceae CITES Listing Appendix I Common Names Cycad Trade All South African Cycad Species (Encephalartos Spp
SANBI IDentifyIt - Species Encephalartos Family Zamiaceae CITES Listing Appendix I Common names Cycad Trade All South African cycad species (Encephalartos spp. and Stangeria eriopus) are listed on CITES Appendix I. While no international trade is permitted in wild plants, trade is permitted in artificially propagated plants that meet certain requirements, for example, the stem diameter is less than 15 cm. The National Cycad Policy, when redrafted, will detail trade standards such as the types of shipping containers that may be used, how these containers should be sealed and when microchips are needed. Once completed, this information will be made available on the DEAT website (www.environment.gov.za). Identifying cycadsUnless complex botanical keys are used, specific cycad identification is very difficult. However, as all cycads are protected by CITES and national legislation, it is sufficient to recognise that a plant is a cycad. Become familiar with the terminology of cycad structure and the key to cycad genera, but always remember to call an expert for assistance (see Contacts). Note that there are three plant families containing cycads. Of the two genera found in South Africa, Stangeria has a single species, Stangeria eriopus. This plant, which occurs on the East coast of South Africa, has soft, fern-like pinnate leaves from 30cm to 2m long (see picture). Lateral veins arise at almost right angles to the midrib of the leaflets. Members of the genus Encephalartos can be recognized by the following basic characteristics: Leaves are pinnate, leaflets with sunken, parallel veins (no midrib). Leaflets are hard and prickly and DO NOT bend easily: they may be deep green, blue green, or grey. -

These include the declaration of “Bioregions” and the publication of “Bioregional Plans”. Bioregional plans are usually an output of a systematic spatial conservation assessment of a region. They identify areas of conservation priority, and constraints and opportunities for implementation of the plan. The precursor to a Bioregional Plan is a Biodiversity Sector Plan (BSP), which is the official reference for biodiversity priorities to be taken into account in land-use planning and decision-making by all sectors within the District Municipality. The overall aim is to avoid the loss of natural habitat in Critical Biodiversity Areas (CBAs) and prevent the degradation of Ecological Support Areas (ESAs), while encouraging sustainable development in Other Natural Areas. -

Evolutionary Signal of Leaflet Anatomy in the Zamiaceae
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Evolutionary signal of leaflet anatomy in the Zamiaceae Coiro, Mario ; Jelmini, Nicola ; Neuenschwander, Hanna ; Calonje, Michael A ; Vovides, Andrew P ; Mickle, James E ; Barone Lumaga, Maria Rosaria Abstract: Premise of research: The morphology of leaves is shaped by both historical and current se- lection acting on constrained developmental systems. For this reason, the phylogenetic signal of these characters is usually overlooked. Methodology: We investigate morphology of the leaflets of all gen- era of the Zamiaceae using multiple microscopical techniques to test whether leaf characters present a phylogenetic signal and whether they are useful to define clades at a suprageneric level. Pivotal re- sults: Our investigation shows that most genera are quite uniform in their leaflet anatomy, with the largest genera (Zamia, Encephalartos) presenting the highest degree of variation. Using both Bayesian and parsimony methods on two different molecular scaffolds, we are able to show that leaflet anatomy has a strong phylogenetic signal in the Zamiaceae and that many clades retrieved by molecular analyses present potential synapomorphies in their leaflet anatomy. Particularly, the placement of Stangeria ina clade with Zamia and Microcycas is supported by the presence of both an adaxial and an abaxial girder sclerenchyma and the absence of sclerified hypodermis. The placement of Stangeria as sister to Bowenia, on the other hand, is not supported by our analysis. Instead, our results put into question the homology of the similar guard cell morphology in the two genera. Conclusions: We show that leaflet anatomy has a substantial amount of phylogenetic signal in the Zamiaceae, supporting relationships that are not supported by general morphology. -
