Description and Ethnobotany

Growth Form Perennial shrub up to 4m tall.
Foliage Unlike other members of the cactus family (Family Cactaceae) which lack leaves or have tiny leaves which quickly fall off, this species has large leaves which remain on the plant. Green leaves are elliptic with wavy leaf margin. Leaf surface appears wrinkled with leaf blade bulging between veins.
Stems The woody stems are heavily armed with dense clusters of black, needle-like spines.
Flowers Orange-red, rose-like flowers are composed of about 10 obovate to oval petals. Bisexual flowers have a compact column of white stamens and styles in the centre.
Fruits Yellow, funnel-shaped fruits are fleshy with several black, disc-shaped seeds.
Ethnobotanical Uses Medicinal ( The leaves are used in Malaysian folk medicine to treat cancer, rheumatism and ulcers. Tan et al. (2005) found that leaf extract was toxic to breast cancer cells, while Sim et al. (2010) found that it did not have toxic effects on healthy mice after oral ingestion.  )
