May Rose (Rosa majalis Herrm.). This species grows in meadows and river valleys. It is a xero-mesophytic shrub from 20 cm to 2 m high, with bright brown-red bark on the thin branches. Thorns are curved and usually arranged in pairs. Compound leaves are thin with three to seven elliptical or ovate leaflets. Pink flowers are usually borne singly and are 3 to 6 cm in diamter. Orange-red fruits are smooth, fleshy, orbicular, seldom ovate or elliptical, orange-red, with deciduous sepals. Edible fruits have thick flesh containing large amounts of sugars, vitamin C and carotene so that they are widely used for the production of vitamin preparations.
