Nicotiana azambujae (Solanaceae): A wild tobacco presumably extinct rediscovered after 73 years

Nicotiana azambujae is an endemic species from Santa Catarina state, southern Brazil, that was described in 1964 and has not been seen since then. During fieldwork, we found a population in Alto Matador, about 70 km from the presumable type collection, after 73 years of its last known collection. Thus, we bring the first in vivo pictures of this species, assess its conservation status, update the morphologic description and discuss its habitat preferences. Also, we discuss a possible mistake in the type of voucher label from the originally collected locality.
