- Aquilegia transsilvanica — A species of herbaceous perennial plants in the genus Aquilegia, endemic to the mountain chain of the Romanian Carpathians (especially in the high limestone areas of Bucegi, Piatra Craiului, and Făgăraș); this structural plant stands out for its large, intense blue-violet flowers, being declared a monument of nature and strictly protected in alpine reserves due to its restrictive geographical range.
- Asperula gussonii — The scientific name of a dwarf perennial herbaceous plant in the family Rubiaceae, endemic to the high, rocky mountain zones of Sicily (especially the Madonie Massif); this rare species forms dense, xerophytic cushions structurally adapted to survival in alpine limestone screes, featuring prostrate stems, small opposite or whorled leaves, and tubular pink or white flowers.
