The difference between Lycopodium and Lycopodium

1. Difference of blades

The leaves of Lycopodiella are spirally arranged, subulate to linear, gradually pointed at the apex, with entire margins without serrations and papery texture.

The leaves of Lycopodium are needle-shaped, about 3-4 mm long, with long awn-like tails at the tip that are easily fallen off, and are dark green in color.

2. Difference of sporangium

The sporangium spike of the lycopodii is single and located at the top of the twigs. It is short cylindrical and usually droops when mature. It is about 3-10 mm long and 2-2.5 mm in diameter. It is light yellow in color. The sporangium leaves are ovate-rhombus-shaped and arranged in a shingle-like manner. The apex is acute and caudate, with irregular serrations on the edges. The sporangium grows in the axils of the spore leaves, is round and kidney-shaped, and is yellow in color.

There are usually 2-6 sporangia of Lycopodiella, growing on the upper part of the spore branches, about 2.5-2 cm long, and the sporangium leaves are ovate-triangular, with an acute tip and a pointed tail, and serrated edges. The sporangium is kidney-shaped and light yellow in color.
