What is the difference between the citron tree and the pomelo tree? A quick guide to tell them apart
I. Leaf differences
The citron tree's leaves are light green, broadly oblong, with long serrations along the leaf edges, and wingless petioles.
The pomelo tree's leaves are relatively thick, with a richer color, and are broadly ovate or elliptical in shape.
II. Flower differences
The citron tree's flowers form short racemose inflorescences, usually terminal or axillary, with 5 fleshy white petals.
The pomelo tree's flowers form racemose inflorescences, sometimes with additional axillary single flowers; the flowers are white, and the buds are pale purplish-red, faintly milky white.
III. Fruit differences
The citron tree's hesperidium is long elliptical or ovate, with a milky protrusion at the fruit apex, and turns lemon-yellow when ripe.
The pomelo tree's fruit is spherical, pear-shaped or broadly conical, and pale yellow or yellow-green.
