  • Description

    Species Description - Consonant with its extreme southern distribution, A. bustillosii is one of the most reduced species of the genus, a chamaephytic subshrub unique in its nearly always solitary flowers and in having spine-tipped old branches. It shares with A. uspallatensis the otherwise unique character of several small trichomes at the base of the anther theca slit. Unlike A. uspallatensis, A. bustillosii shares the short (3-3.6 cm long) fusiform capsule type of A. geranioides and A. glutinosa. The only other Argylia to occur within most of its range is the completely different A. robusta, at the opposite extreme of the genus in its robust herbaceous growth form, large leaves, and multi-flowered racemose inflorescence.

  • Distribution

    This is the southernmost species of Argylia, ranging from 35° to nearly 40°S, rarely north as far as 32°40'S. It occurs in the Andes mostly between 1200-1800 m, mostly in the provinces of Mendoza and Neuquén in Argentina but also crossing the Chilean border into the Provinces of Colchagua and Bío-Bío.
