| Foliage | The spines are modified leaves. The spines are arranged in clusters known as areoles, and there are about 35 areoles per stem section (known as an internode). |
| Stems | The stem is divided into pad-like sections known as internodes. The pads are oval-shaped and about 15 cm long. |
| Flowers | Bright yellow flowers are cup-shaped. |
| Fruit | Berry-like, pear-shaped fruits are purple-red (6.1 cm long, 3.1 cm wide). The sticky, viscous flesh contains about 125 flat to curved seeds per fruit (4-5 mm wide). |
| Ethnobotanical Uses | Food (Fruit or Vegetable): The fruits can be used to prepare an alcoholic drink. They are sometimes eaten when other food sources are scarce. Medicinal: This species contains polysaccharides that help to decrease glucose levels in diabetic mice (Zhao et al 2011). These polysaccharides have potential as a treatment for diabetes. |
