Osteospermum burttianum |
Osteospermum burttianum is a species of plant from South Africa.
This shrublet is densely leafy and hairless. It grows up to 1 m (3.3 ft) tall. [1]
The hairless leaves are attached directly to the stems and are alternately arranged. They have a distinct midrib and the margins are either finely toothed or rough with small, brownish hairs. [2] They have a leathery texture. [3]
Flowers are most common between December and May. [3] Flowers may, however, be present until August. They are yellow in colour. [1] They grow in solitary capitula and are heterogamous. They grow on stalks that are 3–10 cm (1.2–3.9 in) long with 1-3 bract-like leaves. [2]
The involucre has a diameter of 10–15 mm (0.39–0.59 in) and is made of 8-13 narrow bracts. They have short. dark-tipped glandular hairs and net-like veination. [2]
The ray florets are female. There are 8-11 of them per flowerhead. The tube lobes are somewhat oval shaped and crested at the tips. They lack a midvein. The ovary is a narrow hairless and two-veined oblong. [2] In the male florets, the stamen are 2 mm (0.079 in) long. The style is sterile and tipped with a cone surrounded by a fringe of short hairs. [2]
This plant produces obscurely ribbed achenes (dry fruit containing a single seed) [1] They are 5–7 mm (0.20–0.28 in) long. [3]
This species is endemic to the Langeberg Mountains in the Western Cape of South Africa. It has a range of less than 500 km2 (190 sq mi), in which two populations occur. [1] [4] It prefers steep rocky sandstone slopes. [3] It is found on south facing slopes at an altitude of over 1,000 m (3,300 ft). [2]
This species is named after B.L. (Bill) Burtt in honour of his contributions to the knowledge of South African phytogeography and the family Asteraceae. [2]
While Osteospermum burttianum does not currently experience any threats, its small range means that it is currently classified as rare by the South African National Biodiversity Institute. [4]
