Caralluma oxyodonta Chiov.
Sharp-toothed Caralluma
A succulent from the Horn of Africa described by Chiovenda. The epithet 'oxyodonta' (from Greek 'oxys', sharp, and 'odous', tooth) refers to the prominent sharp teeth adorning the stem angles, a diagnostic feature. Grows in arid and semi-desert scrublands of Ethiopia and Somalia, often on calcareous stony soils. Stems are robust, erect to decumbent, quadrangular, bluish-green. Flowers are medium-sized with lanceolate petals, brownish-red with darker veins.
