Bushveld Crossandra – Crossandra greenstockii - Acanthaceae

Bushveld Crossandra – Crossandra greenstockii - Acanthaceae

The following quotation is from Braam van Wyk’s book “A photographic Guide to Wild Flowers of South Africa”

An erect perennial herb up to 30cm high, sprouting annually from a woody rootstock; occurring in bushveld.

When the dry capsules are wetted by rain, they split explosively, ejecting the seed some distance from the plant.
 Upon wetting, flat hairs on the seed uncurl and become sticky, causing them to adhere to wet soil.
