Origin and Habitat: Ethiopia, Kenya, Eastern Uganda. In Ethiopia Caralluma turneri is very common in the area around Dire Dawa in the north of Harerghie Region and also occurs, albeit more sparsely, through the Rift Valley at least as far south as Lake Abiata.
Habitat and ecology: Caralluma turneri grows in close proximity to the habitat of Caralluma dicapuae, but there is at least a partial ecological separation. C. turneri preferring rocky slopes while C. dicapuae prefers flatter areas with deeper soils. There is some indication that the two species are at least partially isolated through pollen vector specificity.

Description: Caralluma turneri is an exquisite and distinct “spidery flowered" species. The main distinguishing is that it flowers in the upper half of stems which is distinct thin, cylindrical and deciduous. It forms tangled clusters up to 45 cm tall and 50 cm across. It is closely related to Caralluma priogonium and Caralluma gracilipes.
Stems: 5-15 cm long, lower part of branches 8-20 mm across, grey-green to brown, 4-angled, distinctly heteromorphic, upper (flowering) part tapering, very slender, cylindrical, sometimes branched, about 30 cm long, 3-4 mm in diameter, more or less 4-angled, bearing remote clusters of 1-4 pendent flowers, becoming woody in fruit, eventually deciduous. Ribs remote, serrate (saw-like), tubercles 8-14 mm long.
Leaves: Rudimentary about 2 mm long, lanceolate or subulate, succulent.
Inflorescence: 1-4 cm apart from each other, with 2-4 flowers. Flower-stalks 3 - 6 mm long, spreading.
Flowers: Sepals 2 mm long, long acuminate. Corolla, narrowly campanulate, deeply divided almost to the centre. Lobes obliquely oblanceolate to spatulate, mobile, pendent, apiculate, flexibly attached, 8-12 mm, 2-3 mm wide, blackish- to brownish purple, usually with some cream-coloured transverse bands, rarely entirely dark, almost completely folded back along the midrib with long purple hairs towards base. Hairs clavate purple, vibratile. Corona 0.7 mm, short-stalked. Outer corona-lobes small spreading 0.7 mm long, rectangular or squarish, deeply 2-horned, appendages filiform. Inner lobes erect, more or less oblong, apically weakly irregularly thoothed, about 1.5 mm long, apically reaching far over the style head, touching each other in the upper half.
Fruit: Grey to straw-coloured, 8 cm long and 0.5 cm in diameter.

Caralluma turneri Photo by: Giuseppe Distefano
The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More...
Cultivation and Propagation: Caralluma turneri is a relatively quick-growing species and not as difficult to cultivate as was originally thought. It can stand drought for quite a period, which is the only time when it loose its leaves. Keep dry in Winter. Water a little more than other succulents in Summer.
