Flowering stems are several times di- or trichotomously branched, forming a large inflorescence that is gray-woolly throughout. Involucres 3-4 mm. long, conic, usually with 3 erect teeth, borne singly throughout the inflorescence and subtended by a pair of leafy bracts. Tepals 6, cream to pink, 3-4 mm. long, the outer segments oblong and twice as broad as the inner segments.
