Aloiampelos decumbens, formerly Aloe decumbens, the Langeberg rambling-aloe, is a sprawling, succulent plant that is endemic to the fynbos vegetation of the Langeberg Mountains near Swellendam and Riversdale in the Western Cape, South Africa.

Description

This plant is decumbent - as its name suggests - and its long, thin branches sprawl for up to 1 meter along the ground and over the rocky outcrops where it grows.

Its bright scarlet flowers appear on and off throughout the year, regardless of season, though usually in January and December. The individual flowers are brightly coloured and large like those of A. ciliaris . However they appear only very sparsely on the relatively small, thin inflorescence. They also share the long, slender perianth of A. gracilis - not A. ciliaris's green-tinted and constricted opening to the perianth.

Natural distribution

Aloiampelos decumbens survives in small, isolated pockets growing in coarse sandstone sands, on cliffs and steep slopes in the Langeberg mountain range of the Western Cape, South Africa. Of the eight isolated sub-populations, one exists as far west as the vicinity of Swellendam, and one population is protected in the Boosmansbos Wilderness Area.

It is possible that further undiscovered populations survive in the remote and inaccessible Cape Fold mountains. [2]

Taxonomy

This plant is sometimes described as being merely an isolated subspecies of Aloiampelos gracilis which occurs much further east in the area around Port Elizabeth. Aloiampelos decumbens is also clearly a close relative of Aloiampelos juddii which similarly occurs only in an isolated pocket of fynbos vegetation, further west near Cape Agulhas. However, among other key differences, Aloiampelos decumbens is a much thinner and more decumbent species. [3] [4]

Fynbos Shrubland and heathland ecoregion of southwestern South Africa

Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting about 80% species of the Cape floral kingdom where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it.

Langeberg

The Langeberg Range is a mountain range in the Western Cape province of South Africa. Its highest peak is Keeromsberg at 2,075 m that lies 15 km North East of the town of Worcester. Some of the highest peaks of the range are located just to the north of Swellendam, in a subrange known as the Clock Peaks whose highest point is the 1,710 m high Misty Point. Local lore states one can tell the time by means of the shadows cast by the seven summits of the Clock Peaks.

<i>Mairia</i> Genus of plants in the daisy family from South Africa

Mairia is a genus of perennial herbaceous plants assigned to the daisy family. All species have leathery, entire or toothed leaves in rosettes, directly from the underground rootstock, and one or few flower heads sit at the top of the stems that carry few bracts. These have a whorl of white to mauve ray florets surrounding yellow disc florets in the centre. In general, flowering only occurs after the vegetation has burned down. The six species currently assigned to Mairia are endemic to the Western Cape and Eastern Cape provinces of South Africa. Some of the species are called fire daisy in English and vuuraster in Afrikaans.
