Calectasia gracilis, commonly known as Blue tinsel lily is a plant in the family Dasypogonaceae growing as a spreading, tufted, woody, perennial herb. It is similar to the other species of Calectasia and has only been recognised as a separate species since a review of the genus in 2001. It is distinguished from the others mainly by having a more slender growth habit, lack of a rhizome and leaves which are glabrous, smaller than those of other Calectasia species and sometimes lacking a sharp tip.
