Sedges growing amongst the paving in my garden in Tarlton (Gauteng, South Africa). You can see what the full plant looks like in my Nature Journal.
Grasses (Poaceae – Gramineae) are characterised by ‘nodes’ along the stem – or jointed stems – as opposed to ‘sedges’ which have stems with no joints and which belong to another family. The family comprises about 104 genera and more than 5 000 species world-wide. In rather arid southern Africa there are roughly 40 genera and 400 species. They are found throughout the region, in particular habitats. Some species e.g. in the genus Tetraria are endemic (occur nowhere else in the world) to the winter rainfall region of the Western Cape, South Africa.
