Pelargonium trifidum used to be called P. fragile and before that P. tripartitum. Fragility is still suggested by the Afrikaans common name of maklikbreekmalva (easily breaking pelargonium). The tripartitum specific name referred to the lobed leaf shape.
This is a sprawling shrublet that grows to 60 cm, occasionally 1 m, the stems are brittle; the upper ones soft, the base woody.
The species occurs widespread in the south of South Africa, from Worcester in the Western Cape to Peddie in the Eastern Cape, growing on dry slopes. This plant was seen in the southern Cape near Van Wyksdorp near the centre of its distribution.
The habitat is scrubveld in clayey soils, the plants often enmeshed in spekboom and guarri. The species is not considered to be threatened in its habitat early in the twenty first century (Vlok and Schutte-Vlok, 2010; www.plantzafrica.com; http://redlist.sanbi.org).
