Local Context
So far only one record from the road that goes to the Southern Cross School. Identification
- Growth: Low, bushy perennial herb (20–60 cm tall) forming loose clumps from a tough, woody base.
- Leaves: Bright green leaves deeply divided into narrow finger-like lobes, arranged in opposite pairs along the stems.
- Flowers: Small cream or pale yellowish trumpet flowers with a long, needle-thin tube opening into a flat, 5-lobed face, crowded on upright spikes.
- Texture: Stems and leaves feel rough and scratchy like fine sandpaper due to tiny, stiff hairs.
- Fruit: Small, 2-lobed dry capsule tucked snugly inside a pale, papery cup.
Did You Know?
Thriving across open bushveld, calcrete ridges, and the harsh, alkaline margins of seasonal pans, Chascanum pinnatifidum uses a clever tactile defence against the elements. Its stems and deeply lobed leaves are coated in fine glandular hairs that produce a faintly sticky secretion. In dry, dusty environments, this residue catches airborne silt and sand grains, creating a natural microscopic "dirt shield" (a strategy known as psammophory) that deters chewing insects and buffers the foliage against intense solar glare.
