Found and lost again: Rediscovery of Mollinedia myriantha (Monimiaceae) after 123 years and perspectives for conservation of the family in Brazil

Mollinedia myriantha Perkins (Monimiaceae) is a tropical tree described by Perkins (1900) based on a collection of the French botanist Auguste F. M. Glaziou collected in 1892 in the mountainous region of Rio de Janeiro state, Brazil. The species was rediscovered in 2015 after 123 years, from Glaziou's report at the type locality, however, in subsequent fieldwork (2018 - 2019) the sole rediscovered individual was found dead. In this study, we report this rediscovery and we present the risk assessment including the Probability of extinction - P(E), also we provide a lectotypification, along with morphological description, geographic distribution map and conservation comments for this species. We also discuss the conservation status of Monimiaceae in Brazil.
