Despite the long-standing cultural importance and botanical interest in Vanilla, many taxa belonging to genus remain poorly understood. Vanilla species generally have broad geographical ecological distributions. Most are found multiple countries, while local endemics rare. Many names proposed eighteen nineteenth centuries cryptic unused despite having priority over more recently names. Relatively few been well-documented, both locally across their entire distribution range, a significant...

ABSTRACT The pantropical Vanilla is the most species-rich genus among Vanilloideae (Orchidaceae). With 38 species, Brazil center of diversity for Vanilla. Several Brazilian taxa are considered obscure, as species boundaries often unclear when studies performed exclusively on dried specimens. This case sprucei Rolfe, a rare taxon with ephemeral flowers that has been referred to based specimen collected in Colombian Amazonia. We present data confirming its occurrence Brazil, together taxonomic...
