Quillaja Molina, a genus of small evergreen trees with three to four species from temperate South America, was included in Rosaceae as part of Quillajoideae (Takhtajan, 1997) or as Spiraeaoideae-Quillajeae (Robertson, 1974), but wood anatomical data, etc., suggest that it should be removed (Lotova & Timonin, 1999; cf. Zhang 1992).
