The difference between large-flowered sorrel and wood sorrel

Article Catalog

1. Differences in leaves

2. The difference between flowers

Leaf differences: The former is a basal leaf, and the small leaves are obovate or broadly obovate, with a smooth surface and hairs on the back. The latter has basal leaves and upper stem leaves, and the small leaves are inverted heart-shaped, with pubescence on both sides. Flower differences: The former has umbels, basal or subbasal, purple-red. The latter is solitary or several flowers are gathered into umbels, axillary, yellow.

1. Leaf differences

Oxalis grandiflora has basal leaves with thin petioles, about 7-10 cm long, and joints at the base. The small leaves are obovate or broadly obovate. It is about 1.5-2 cm long and 2.5-3 cm wide. The apex is blunt and round, the base is wide wedge-shaped, the surface is smooth and hairless, and the back is sparsely pubescent.

Oxalis is divided into basal leaves and upper stem leaves, which are alternate on the stem. The small leaves are inverted heart-shaped, smaller than the former, about 4-16 mm long and 4-22 mm wide, with pubescence on both sides.

2. Flowers The difference

The large-flowered wood sorrel has umbels, which are basal or nearly basal. They are obviously longer than the leaves. The petals are purple-red in color and are broadly obovate.

Oxalis flowers are solitary or gathered into umbels, axillary, as long as the leaves. The petals are yellow in color and oblong-ovate in shape.
