Lobostemon glaber, the renoster healthbush, is a species of plant from South Africa. It is in the forget-me not family.

Description

This shrub grows 30–60 cm (12–24 in) tall.[2][3] It has both woody and herbaceous branches. The herbaceous branches and the stemless lance-like leaves are hairy.[3] The hairs are not of uniform length. They may be either of two size classes or fall along a continuous spectrum of lengths.[3]

White or pale pink funnel-shaped flowers are present between August and November.[2] They are borne in cymes. The buds are loosely arranged to form a globose unit or are arranged in two distinct parallel rows, spreading greatly in fruiting stage.[3] The anterior petals are longer and have larger lobes than the rest. They are not hairy.[3] The staminal scales are triangular with lateral lobes.[2] They are inserted below the throat of the corolla tube, 3.8–4.5 mm (0.15–0.18 in) above the base of the corolla tube.[3]

It may be confused with Lobostemon trichotomus, but the hairs on the mericarpids (nutlets) of Lobostemon glaber are diagnostic.[3]

Distribution and habitat

This species is found growing from the Koue Bokkeveld to the Cape Peninsula and Witteberg.[2] It is found growing on shale soils and rocky slopes.[3]

Ecology

This species is popularly visited by bees. It produces a large quantity of nectar, making it a high reward species.[4] Like other Lobostemon species, it is able to resprout after a fire.[3][5]
