Colobanthus is a large genus of small, cushion-like herbaceous plants in the family Caryophyllaceae, sometimes known as "pearlworts", a name they share with plants of the related genus Sagina. C. quitensis is the world's southernmost dicot, and one of only two native extant flowering plants of Antarctica.
