Phanerophytes; endemic to mountain ranges of Buenos Aires province. Critically Endangered, reasons unknown ( Delucchi 2006).

Characteristics. Dioecious species. Globose shrub, 1–5 m tall. Young branches pubescent with alternated leaves. Leaves: obovate shape, length–width ratio between 1.8:1 and 3.6:1. Capitulum: sessile or subsessile, with yellow florets and white pappus. Male capitulum with tubular disc florets, up 3 mm long; female capitulum with filiform florets, 4–5 mm long.

Comments. This is a very frequent species in the study area. It grows in various habitats, from deep soils of grasslands, to shallow soils and cracks of the slopes and summit. It is similar to Baccharis draunculifolia ssp. dracunculifolia , but it has linear leaves (length-width ratio 6:3:1–11:6:1), and it does not occur in south-eastern Buenos Aires province.
