The actual species of the true shamrock has long been debated, but the plants most often favored and used are the white clover ( Trifolium repens ), the black medic ( Medicago lupulina ), the wood sorrel ( Oxalis acetosella ), and a hop clover ( Trifolium minus ). All are classified in the division Magnoliophyta , class Magnoliopsida. Trifolium and Medicago are in the order Rosales, family Leguminosae; Oxalis is in the order Geraniales, family Oxalidaceae.

shamrock

shamrock. References to the wearing of shamrock on St Patrick's Day can be traced back at least to 1681. The legend that the plant derives its association with the saint from his use of its three leaves to explain the concept of the Trinity was first recorded in 1726. Shamrocks were widely used in Volunteer flags and other Irish military insignia during the second half of the 18th century. Like the harp, the shamrock was subsequently incorporated into the official symbolism of the United Kingdom. George IV wore shamrock during his visit to Ireland in 1821, and it was included in the badges of the Royal Irish Constabulary and in the flags of Irish regiments of the British army.
