First, the size difference:

Botanically speaking, Pogostemon rugosa and Mentha haplocalyx belong to Labiatae, and both have a refreshing fragrance, so they are very similar. Pogostemon cablin just has another name, which is called "peppermint".

Second, the difference between leaves:

It is not enough to compare the size of leaves, because sometimes two things are not compared together. Note the base of the leaf, which is connected with the petiole. The leaves of Pogostemon cablin are heart-shaped at the base. Of course, the gap in my heart is shallow. The leaf base of mint is wedge-shaped or nearly round, that is, "heart-shaped" with no small gap. What's more, the leaves of Pogostemon cablin have a sense of contraction, while the leaves of mint are relatively flat.

Third, the difference between flowers:

Pogostemon cablin and mint are both multi-flowered cymes, but there are obvious differences. The flowers of Pogostemon cablin grow at the "top" of the main stem or lateral branches, which is called "terminal" in botany. The flowers of Pogostemon cablin are very dense and have a cylindrical spike shape. And mint flowers grow at the junction of leaves and main stems, which is called "axillary" in botany. To put it bluntly, the flowers of Pogostemon cablin grow on the top of the head and the flowers of Mint grow under the armpits.
