Lachenalia unifolia, the banded viooltjie, is the most common Lachenalia species in the Cape Floristic Region of South Africa.
Description
[edit]This bulbous geophyte grows 8–35 cm (3.1–13.8 in) tall.[2] It has one linear leaf, the lower part of which is banded with green and maroon stripes.[3] It is 8–32 cm (3.1–12.6 in) long and clasps the stem at the base.[2] The tuber contains a multi-layered tunic. The outer layers are dark brown and spongy while the inner layers are a translucent white colour.[2]
Flowers are present between August and October. They are pale blue, pink or pale yellow in colour with white tips.[3] They are borne in a raceme, which may have few or many flowers.[2]
The ellipsoid capsule contains glossy black spherical seeds.[2]
Distribution and habitat
[edit]This species is endemic to the Northern Cape and Western Cape of South Africa.[4] It is found on deep sandy flats and stony clay slopes between Namaqualand to Bredasdorp.[2]
Conservation
[edit]Lachenalia unifolia is the most common Lachenalia species and is considered to be of least concern by the South African National Biodiversity Institute (SANBI). While it is declining due to a combination of habitat loss and alien vegetation, the rate of decline is not currently considered high enough to put this species at risk of extinction.[4]
Uses
[edit]This species is valued as an ornamental plant.[5]
