Asepalum Eriantherum
''Asepalum'' is a genus of flowering plants belonging to the family Orobanchaceae. Its native range is Northeastern and Eastern Tropical Africa Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropi ... to Iraq.

Wessel Marais
Wessel Marais B.Sc., M.Sc. (1929-2013) was a South African botanist and plant collector. Wessel was born in Colesberg, Northern Cape Province, on 28 December 1929, the youngest of the ten children of Barend Pieter Marais, the last blacksmith and wagon builder of Colesberg, who was of French Huguenot descent. He studied at Pretoria University (1947-1951) where he obtained an M.Sc. in Botany for the thesis 'A Morphological study of an indigenous species of rice, ''Oryza barthii'' A. Chev.'. He then (1952) joined the National Herbarium (PRE) where he undertook fieldwork during an internship in Kruger National Park and in Namibia. From 1953 to 1955 he was director of the Albany Museum Herbarium (GRA) in Grahamstown, where he studied South African Cruciferae for the Flora of Southern Africa. He carried out collecting trips to the Southwestern Cape Province, Natal, Lesotho, the Transkei, Pondoland, Griqualand East and other localities. He collected over 1,500 specimens jointly with Va ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orobanchaceae
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot fami ...

Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.
