Tritoniopsis lata var. lata is a deciduous, cormous perennial growing to between 25 cm and 50 cm in height.
The plant annually produces from one to three narrow, sword-shaped leaves, each with one to three longitudinal veins. The leaves are enveloped by a fibrous membrane at ground level.
The distribution of the variety is in the Western Cape, from the Cape Peninsula to Worcester and Bredasdorp.
The plant grows on fynbos slopes in seasonal seeps or near watercourses in sandy and rocky places. The plant is not considered threatened in habitat early in the twenty first century.
There is also a T. lata var. longibracteata growing in the Western Cape (Manning, 2007; iSpot; www.redlist.sanbi.org).
