Lobostemon belliformis, the Gouriqua lobostemon or beaut healthbush, is a critically endangered species in the forget-me-not family. It is known from a single locality on the Riversdale Plain in South Africa.

Lobostemon belliformis growth form

This species is a woody shrub that has a thick basal trunk.[1] It branches freely to and form a bright green mound with a rounded habit, growing up to about 2 m (6.6 ft) wide and 1–1.5 m (3.3–4.9 ft) high.[1][2] The herbaceous branches are covered in hairs.[2] The hair-covered leaves are long and oval-shaped. These hairs give them a rough texture.[1]

The tubular pink or red flowers flare wider at the mouth before opening.[1] They are large (petals are approximately 44–45 mm (1.7–1.8 in) in length) and the outward facing sides of the petals are covered in hairs.[2] They are borne in cymes at the ends of branches between July and October.[3] The stamens are slightly dissimilar in length and the staminal scales are inserted well below the throat of the corolla tube, 3 mm (0.12 in) above the base. The staminal scales are reduced to swellings and they lack lateral lobes.[3] The seeds appear as four little nutlets that have spiny tips.[1]

Distribution and habitat

This species is known from the Gourits River.[3] In present times, it is a highly restricted species and is known from one small sandstone outcrop on the Riversdale Plain.[4] Historically, it was also found on coastal limestone.[2][3]

Ecology

This appears to be a slow growing species that escapes fire by growing on rocky outcrops and by having thick bark. The generation time is expected to be around 40 years, which is long for a species that lives in an ecosystem in which fire plays such a pivotal role.[4] Over time, plants tend to get increasingly woody and produce fewer flowers. They re-seed in large numbers following a fire. Some shrubs may also resprout after fire if they are not too badly burnt.[1]

The flowers attract both birds and bees, particularly the orange-breasted sunbird, the lesser double-collared sunbird, and the cape sugarbird.[1]
