Along with the crown, scepter, and orb, there was a wreath resting on the Queen's coffin.
According to a tweet from the Royal Family's official account, the flowers were chosen by King Charles III and had their own symbolism: "The wreath contains foliage of Rosemary, English Oak and Myrtle (cut from a plant grown from Myrtle in The Queen's wedding bouquet) and flowers, in shades of gold, pink and deep burgundy, with touches of white, cut from the gardens of Royal Residences."
Later on, a handwritten card from her son, the new king, was placed on the coffin. The card read, "In loving and devoted memory. Charles R."
