Oxalis corniculata,
a 10-30cm tall perennial herb that does sleep movements, closes its
leaves during nighttime. 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, peduncles face
downward and set cylindrical capsules at their tips, facing upward.
The capsules split open and disperse many seeds as they ripen. Bloom
time: May-July. |
