The structure of the head is typical of the Asteraceae: the stalk supporting a globular shell composed of several scales available that serve as protection for the hawksbill woolly receptacle which fits on two types of flowers: the flowers outside ligulate (absent in this species) , and the flowers central tubules. The scales are hairy with short brown margin (not blackened). The size of the head is less than 6 mm. Length of peduncles: 2 to 8 mm.

· Androecium: stamens with free filaments 5 are welded but anthers that form a sort of sleeve enveloping the stylus.

· Gynoecium: the two carpels, forming a unilocular inferior ovary bicarpellare. The ovary bears a single egg anatropo. The stylus is one that ends in a profound stigma bifid.
