black-stick lily

Xerophyta retinervis Baker

Xerophyta retinervis, known as black-stick lily, is a deciduous perennial in the Velloziaceae family. It can grow up to 2 metres tall and is characterized by its stout, erect stems covered in fibrous, often blackened leaf bases. This species is native to Botswana, Northern Provinces, and Swaziland. It is adapted to harsh conditions, including drought, fire, and cold. After fire or rain, it produces fragrant blue, mauve, or occasionally white flowers. The plant's structure channels rainwater to its central root system, which runs the full length of the stem. Strap-shaped leaves are arranged in tufts along the stems.

Description

Xerophyta retinervis is a resilient plant species in the Velloziaceae family, known for its ability to survive in extreme environments. Its stems are densely covered with persistent, fibrous leaf bases that often become charred due to veldfires. The plant can reach a height of up to 2 metres. Following fire or rainfall, it produces fragrant flowers that are typically blue or mauve, though white flowers are occasionally observed. The plant's leaf bases are arranged to direct rainwater to the core, where it is absorbed by a dense root system extending along the entire stem. Small, hairy capsules develop after flowering, releasing numerous small, black, angular seeds approximately 2 mm in length. Strap-shaped leaves grow in tufts along the stems.
