Flower buds blood-red, opening to cream-colored or slightly pinkish or yellowish tepals, 6-8 mm. long with a stipe-like base 1-2 mm. long |
Open, branched inflorescence with leafy bracts at the first and second points of branching; involucres usually in capitate clusters, tubular, with 5 erect, short teeth; flowers interspersed with numerous, filiform bracts that protrude form the involucres.
