Among the alpine flora of southern Africa, the poisonous herb Conium fontanum var. alticola can be found growing near streams and seepages. This high-altitude variety is adapted to moist, cool environments in mountainous regions, particularly in the Drakensberg range. Like other members of its genus, this plant contains dangerous piperidine alkaloids and poses a severe threat to herbivores and humans.
This biennial or perennial herbaceous plant features highly dissected, fern-like leaves that give it a delicate appearance. The erect, hollow stems are typically green and lack the prominent purple spotting found in some related species. It produces compact, compound umbels of small white flowers at the terminal ends of its branches.
The root system consists of a stout taproot that anchors the plant firmly in damp, rocky soils. Its fruits are small, dry schizocarps that split into two mericarps when mature, facilitating seed dispersal via water currents and wind.
Late spring to summer
The epithet alticola translates to 'high-altitude dweller,' reflecting its specific habitat preference in the mountain systems of Lesotho and South Africa. Despite its toxic nature, it plays a role in its native ecosystem by interacting with specialized montane insects. The plant serves as a stark reminder of the evolutionary defense mechanisms developed by high-altitude vegetation.
