    Characters as given in key; filaments of 2 long abaxial stamens 3-5 mm, of the centric abaxial one 2.5-3 mm; style 2-2.5 mm.—Collections: 13.

    Brushy hillsides and thickets, 5-1000 m, scattered along the coast range of s. centr. Chile from Valdivia n. to Nuble, there extending e. into the foothills of the Cordillera.—Fl. X-III(-?).—Mayu (mayo), palo negro.

    An attractive shrub, small-flowered but highly floriferous, the trunk attaining a diameter (according to Clos) of one to three inches. Father Feuillee, whose early description was overlooked by Linnaeus, found it used in decoction, at Concepcion, as a fleabane and was the first to record the vernacular name mayu, heard in the same region by Ruiz, Pavon & Dombey.
