The difference between ground vegetables and spotted grass

1. Difference of blades

The basal leaves of the ground lettuce are rosette-shaped, spoon-shaped, about 2-5 cm long, with a rounded tip, a cuneate base or gradually narrowing, short rough hairs on both sides, and a petiole. The leaves on the upper part of the stem are elliptical or oblong and almost without petioles.

The basal leaves and lower stem leaves of the spotted grass are oblanceolate or spatulate, usually 3-6 cm long, rarely reaching 12 cm, and all have long petioles. The middle and upper parts of the stem are oblong or narrowly oblong, with a pointed tip and a broad cuneate base, and are covered with stiff hairs on both sides.

2. The difference between flowers

The inflorescence of ground lettuce grows at the top of the stem. It bends when young and gradually elongates in the later stage. It is about 5-20 cm long and usually occupies 1/2-4/5 of the stem. There are 2-3 bracts at the base, and no bracts in other parts. The corolla is pink or blue, with flat, obovate lobes.

The inflorescence of the spotted grass is about 5-15 cm long, with bracts, narrowly ovate or ovate, the corolla is light blue, and the lobes are round.
