  Oleander

  Nerium oleander

  Mistaken for

  Nothing edible, but it is planted along roads and in gardens everywhere, and its straight green stems look like ready-made braai skewers.

  How to tell

  A shrub with long, narrow, leathery leaves in pairs or threes, each with a strong pale midrib; clusters of pink, white or red flowers; and long, thin pods of fluffy seeds.

  What it does

  Cardiac glycosides in every part. It is bitter, so serious poisoning is uncommon, but toddlers have died after eating the leaves. Never use its stems as skewers or its leaves for tea.

  Thorn apple (Datura)

  Datura (the whole genus)

  Mistaken for

  Young plants come up among amaranth (morogo) and other wild greens in maize fields and gardens, and children eat the seeds.

  How to tell

  A coarse, rank-smelling plant with large, irregularly toothed leaves, big upright trumpet flowers, white or purple, and a spiny, walnut-sized capsule packed with small dark seeds. Amaranth has smooth-edged leaves and only bristly flower spikes.

  What it does

  Atropine and scopolamine: dry mouth, hot flushed skin, a racing heart, huge pupils, then delirium and hallucinations that can last a day or more. It has killed adults and children.

  Tree tobacco

  Nicotiana glauca

  Mistaken for

  Wild greens: its large, soft leaves have been picked and cooked as a spinach. It is an invasive weed of roadsides, dry riverbeds and waste ground in many parts of Africa.

  How to tell

  A lanky, hairless shrub or small tree with bluish-grey, rubbery, oval leaves up to 20 cm long, and loose clusters of narrow yellow tubular flowers about 5 cm long at the branch tips. No edible green has that waxy blue-grey colour and yellow trumpet.

  What it does

  Anabasine, a nicotine relative: muscle weakness and paralysis that can stop the breathing after a meal of the cooked leaves. Every part is poisonous, raw or cooked, and ingestion has been fatal.

  Syringa (chinaberry)

  Melia azedarach

  Mistaken for

  Children pick up the berries under the trees: it is planted for shade and has run wild in South Africa, where it is called syringa.

  How to tell

  A tree with large, twice-divided leaves of toothed leaflets, sprays of fragrant lilac flowers in spring, and smooth, round, marble-sized berries that turn yellow and hang on the bare branches through winter.

  What it does

  Neurotoxins concentrated in the fruit: vomiting, bloody diarrhoea, confusion and convulsions a few hours after eating. Poisoning has followed as few as six to nine fruits.

• Hospital1 record nearby

  Euphorbias (milk bushes, naboom, pencil tree)

  Euphorbia (the whole genus)

  Mistaken for

  Prickly pear and other cacti — many African euphorbias are spiny, leafless succulents that look exactly like cacti — and the pencil-stick hedges of Euphorbia tirucalli around farms and villages.

  How to tell

  Break a stem: a euphorbia bleeds white milky latex at once. Cacti such as prickly pear bleed clear or slimy sap, and their spines grow from small fuzzy cushions; euphorbia spines grow singly or in pairs, never from a cushion.

  What it does

  The latex burns skin and mouth, and in the eye can cause temporary blindness. Wear gloves and eye protection near a cut plant, and never rub your eyes.

These are recorded within about 40 km of here in this month, from verified public observations. It is not a complete list of what is dangerous — nothing is — and a species missing from it may still be in your woods. Never eat anything identified from a photograph and a description alone.
