description
Oxalis gigantea is an upright shrub that usually grows up to 2.5 m high, but in individual cases it can also reach heights of 5 to 6 m. The stems have a diameter of 2.5 to 5 cm, they are upright to curved or drooping. They are pale brown, covered with a multitude of spur-like short shoots and initially finely haired, later woody and developing a dark gray to almost black bark . The many, small leaves are fleshy, three-part and come in different sizes. The partial leaves are 3.5 to 7 (rarely up to 14) mm long, have entire margins, inverted heart-shaped and hairless. They are bright green or occasionally hairy.
The inflorescences consist of a single flower or are three- to six-flowered, umbel-like cymes . The flower stalks are up to 3 cm long. The flowers have a diameter of up to 2 cm and are bright yellow in color. The sepals are unevenly shaped, somewhat blunt to the front, hairy at the tip, but otherwise hairless. The petals are egg-shaped. The stamens are wedge-shaped at the base, the five larger ones are hairy. The stylus is hairy, the ovary hairless.
The number of chromosomes is 2n = 18.
