Resumen:
Antiphytum charruasorum, a new endemic species from western Uruguay, is
described. This is the only South American species in the genus with
white corolla and an infra-medial cicatrix on the ventral face of the
eremocarp, both features shared with the North American species of
Antiphytum, in sharp contrast with the blue corolla and the basal
cicatrix at the end of a stipe-like prolongation that characterizes all
South American species in the genus. Antiphytum charruasorum increases
the diversity of the genus in South America, as well as the endemism and
distribution range into Uruguay. Moreover, this new species adds novel
features in Antiphytum such as the irregularly dichasial inflorescences,
the hirsute faucal appendages, the eremocarps with a tissue plug from
the gynobase, and the habitat where the species has been reported.
