Isoetes toximontana, the Gifberg quillwort, is a plant species native to the Northern Cape and Western Cape regions of South Africa. It is known from only 3 sites.[1] The type locality is on the slopes of Gifberg, a mountain forming part of the eastern boundary of the Olifants River Valley. The name "Gifberg" means "poison mountain"; this is in reference to a poisonous tree called "gifboom", Euphorbia virosa, that is endemic to the area. The specific epithet "toximontana" is a Latin translation of the Afrikaans name of the mountain.[2]
Isoetes toximontana is an herb which grows in shallow water, very often emerging above the surface. Leaves are 3-10 per plant, up to 42 mm long, elliptical in cross-section.
