Oxalis corniculata,
a 10-30cm tall perennial herb that exhibits sleep movements,
closes its leaves at night. Stems crawl on the ground or underground
to expand and set 3 heart-shaped leaflets at the tips of long
petioles. The leaflets measure 1cm long. The flowers are yellow and
approximately 8mm in diameter. After the flowers, the peduncles face
downward and set cylindrical capsules at their tips, which face
upward. The capsules split open and disperse many seeds as they
ripen. Bloom time: May-July. |
