Fockea comaru, one of the kambroos that grow large caudices and has milky sap, is a shrub with thin stems that sprawl or twine. The tuber consisting of spongy water retaining fibres is sometimes turnip-shaped, sometimes irregular in shape. This caudex may be situated some distance away from where the stem emerges from the ground.
The leaves are opposite and narrow with margins that are rolled under and the midrib recessed. The leaves become 2 cm long, 5 mm wide. The leaf tip tapers to a point. The flowers have five green and narrow outer lobes and white inner ones that are shorter on a fleshy raised structure. Flowering happens in spring and summer.
The species is distributed from Namibia and Namaqualand across the Karoo and Little Karoo to Willowmore in rocky or sandy places. The species is not considered to be threatened in its habitat early in the twenty first century.
The plant is popular among succulent growers who tend to leave more caudex above-ground than seen in nature (Vlok and Schutte-Vlok, 2010; iSpot; www.llifle.com; http://redlist.sanbi.org).
