Wood sorrel (a type of oxalis) is an edible wild plant that has been consumed by humans around the world for millennia.
The plants are annual or perennial. The majority of species have three leaflets; in these species, the leaves are superficially similar to those of some clovers.
The giraffe is the tallest animal in the world, attaining a height of 5.5 m, its incredibly long neck accounting for much of its height. The long neck has resulted in a complex blood circulatory system, which is not yet fully understood by zoologists. Adult males generally reach a height of about 5 m and females about 4.5 m. Big males can weigh a massive 1 200 kilograms while females usually weigh some 800 to 900 kilograms. Their skin color is tan with light brown patches on females and dark brown patches on males. Both males and females have short horns covered in skin.
The Pretoria National Botanical Garden, located in the suburb of Brummeria in east Tshwane, was established in 1946 after the University of Pretoria’s experimental farm and private properties were acquired by the Department of Agriculture. The garden was formerly known as the Transvaal National Botanic Gardens, and was primarily a research facility under the management of the Botanical Research Institute, which dates back to 1903.
