Bear’s garlic (Allium ursinum) is a protected plants, mesophytic ephemeroid (spring geophytes) plant. The leaf is inverted or invertedbifacial, that is, the palisade tissue is located on the lower side of the leaf blade. The number of stomata per 1 sq. mm of the lower epidermis was calculated: on the 30th day after the onset of spring growth we found 56±1,8 stomata in the lower epidermis and 14±1,6 stomata in the upper epidermis (per square mm). Guard cell size in the lower epidermis was found to be 25±1,5 and 27±1,5 – in the upper.
