Baretia Timaná, gen. nov., a new genus in the plant family Caryophyllaceae from central Chile, is proposed and described. The new monospecific genus differs from other members in the family by possessing a combination of characters that include dioecy, a densely albo-lanuginose indumentum cover, absence of stipules, strongly perigynous flower, a well-developed receptacular cup, style undivided with a slightly capitate stigma, and an indehiscent, one-seeded fruit. The genus includes a single species, Baretia lanosa (Phil.) Timaná, comb. nov. and honors French botanist and explorer Jeanne Baret, the first known woman to circumnavigate the globe as part of the Bougainville expedition around the world (1766-1769).
