Ernst Ule's collecting localities in the Serra do Sincora, Bahia, Brazil and the lectotypification of Anthurium petrophilum (Araceae)

The itinerary of the German botanist and explorer Ernst Heinrich Georg Ule (1854-1915) in central Bahia state, Brazil, is reconstructed from published records, specimen label data and unpublished correspondence. Emphasis is given to his collecting localities in November 1906 in the campo rupestre of the Serra do Sincora, Chapada Diamantina, where he collected type specimens of species from many genera and families. The available information suggests that his collections were made over a wide area along the western side of the Serra, from Camulengo in the south to near Mucuge in the north. Among them is one of the syntypes of Anthurium petrophilum (Araceae), recently re-discovered at the Herbarium Hamburgense (HBG). Ule also collected the other syntype in September 1906 at Maracas, a distinct inselberg highland to the east. Since recent morphological and molecular studies have shown populations from the two areas to be taxonomically distinct, the duplicate at the Berlin Botanical Museum (B) of the Maracas collection is here proposed as the lectotype, since it is the only surviving syntype known to have been seen by K. Krause, the author of the name.
