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. -

Woody Plant Species Used in Urban Forestry in West Africa: Case Study in Lomé, Capital Town of Togo

Available online at www.internationalscholarsjournals.org © International Scholars Journals Author(s) retain the copyright of this article. Full Length Research Paper Woody plant species used in urban forestry in West Africa: Case study in Lomé, capital town of Togo Radji Raoufou*, Kokou Kouami and Akpagana Koffi Laboratory of Plant Biology and Ecology, BP 1515 Lomé - Togo. Accepted 13 July, 2019 Many studies have been conducted on the flora of Togo. However, none of them is devoted to the ornamental flora horticulture. This survey aims to establish an inventory of the woody plant species in urban forests of Lomé, the capital town of Togo. It covers the trees planted along the avenues, in the gardens, courtyards, shady trees and trees used as fences for houses or trees at the seaside. In total, 297 plant species belong to 141 genera and 48 families were recorded. They are dominated by 79% of dicotyledonous, 13% of monocotyledonous and 8% of gymnosperms. Families that are best represented in terms of species are those of the Euphorbiaceae, Arecaceae and Acanthaceae. Alien species represent 69% and African species represent 31% out of which 6% are from Togo. According to the current threatening of the natural habitat by human activities, African native plant species could be more useful for ornamental purposes than exotic plants. Key words: Ornamental horticulture, plant flora, green areas, valorisation, native flora. INTRODUCTION Urban forestry refers to trees and forests located in cities, landscape covered with trees for the physical and mental including ornamental and grown trees, street and parkland health has been documented (Ulrich, 1984). -

Threatened and Rare Ornamental Plants
Journal of Agriculture and Rural Development in the Tropics and Subtropics Volume 108, No. 1, 2007, pages 19–39 Threatened and Rare Ornamental Plants K. Khoshbakht ∗1 and K. Hammer 2 Abstract The application of IUCN criteria and Red List Categories was done for ornamental plants. Main sources of the study were Glen’s book, Cultivated Plants of Southern Africa (Glen, 2002) and the Red List of Threatened Plants, IUCN (2001). About 500 threatened ornamental plants could be found and presented in respective lists. Rare ornamental plants with 209 species is the largest group followed by Vulnerable (147), Endangered (92), Indeterminate (37), Extinct (6) and finally Extinct/Endangered groups with 2 species. A weak positive correlation (r = +0.36 ) was found between the number of threatened species and the number of threatened ornamental species within the families. Keywords: ornamental plants, IUCN criteria, red list 1 Introduction Whereas red lists of threatened plants are being highly developed for wild plants and even replaced by green lists (Imboden, 1989) and blue lists (Gigon et al., 2000), ornamental plants still lack similar lists. A statistical summary of threatened crop plant species was published by Hammer (1999) showing that roughly 1000 species of cultivated plants (excluding ornamentals) are threatened (see also Lucas and Synge (1996). An attempt was recently made towards a red list for crop plant species, which presents about 200 threatened cultivated (excluding ornamentals) plants in the IUCN categories (Hammer and Khoshbakht, 2005b). Now an effort is made to include ornamentals. IUCN has defined six categories for threatened plants – Extinct, Extinct/Endangered, Endangered, Vulnerable, Rare and Indeterminate (see IUCN (2001) for definitions). -
