Acrodon bellidiflorus explained

Acrodon bellidiflorus, the common tiptoothfig, is a mesemb species from South Africa.

Description

Acrodon bellidiflorus is a compact succulent perennial plant.[1] [2] It has a woody taproot with fine roots growing off it. This is the only species in its genus where this trait is common

The deep green leaves are triangular. They have a persistent that turns black with age. The keel and margins may be smooth or may have three or four flexible teeth with broad bases. The number of teeth may also vary between populations. The eastern populations have short visible internodes. Internodes are not visible in other populations.

The flowers are white or pale pink in colour and have a diameter of about 35mm. There is only a single flower at the tip of each flowering branch. They are present between April and July.[3]

Distribution and habitat

This species is endemic to South Africa. It is found growing between McGregor and Bredasdorp and the Klein Karoo. It grows in areas that have renosterveld, coastal fynbos or grassland biomes.

Taxonomy

Initially, Acrodon bellidiflorus was the only species in its genus. A closer examination of Ruschia in 1986, however, found that several species shared traits with Acrodon bellidiflorus, resulting in them being moved to the genus Acrodon.[4]

Conservation

This species is considered to be of least concern by the South African National Biodiversity Institute.[5]
