The difference between snapdragon and snapdragon

1. Difference of blades

Most of the leaves of the willow catfish are alternate, a few are whorled at the bottom and alternate at the top, in the shape of strips, about 2-6 cm long and 2-4 mm wide. The leaves of snapdragon are opposite at the bottom and alternate at the top, lanceolate to oblong-lanceolate, similar in size to the former, with entire margins.

2. Differences in stems

The stems of the willow thorn fish are hairless, relatively erect, and usually branched in the upper part. The base of the stem of snapdragon is hairless, there are glandular hairs in the middle and upper parts, and the base is sometimes branched.

3. The difference between flowers

The inflorescence of the willow fish is racemose, the bracts are linear to narrowly lanceolate, the calyx lobes are lanceolate, and the corolla is yellow. The calyx of snapdragon has five deep lobes, the lobes are oval, and the corolla has a variety of colors, ranging from red or purple to white.
