Toothed clubmoss
There are no underground stems, and the stems are almost upright on the roots and the ground. The root of the stem is slightly slanted and sprouts, so it becomes a stock. The stem also branches 2-3 degrees at the top. The height is 7 to 20 cm, sometimes around 30 cm. Stems and leaves are hard. The leaves are roughly thin and oval with a slight serration on the edge, but are often mutated and are characterized by distinguishing varieties. There is only one main vein, and it protrudes slightly behind. The leaves spiral around the stem, dark green to yellow-green, thin, hard and shiny. Although the spore comes to the upper side of the base of the spore leaf, it appears to stick to the stem as an impression. They usually arrive in the middle of the upper part of the stem, but apparently there is not much difference in the spore leaves, and it does not look like a spike. Leaves near the tip of the stem may be thick, where asexual buds form.
