Henriettea horridula Pilger (1905: 82) . Type:— “ Brazilen. Manaos”, February 1901 , E.H.G. Ule 5398 ( lectotype : HBG522811 ! designated here; isolectotypes : B† [photograph F17263!], CORD00003593!, K000537023!, MG005349 !) . Pilger (1905) described H. horridula based on Ule 5398 , but he did not mention the herbarium where it was deposited. The herbaria B and HBG are the most representative regarding Ule’s collection ( Borges et al. 2018 ). However, only a photograph of this specimen is extant in B herbarium, as the original was probably destroyed during the Second World War. Specimens from this collection are deposited in CORD, HBG, K, and MG , and present labels including the collection locality, plant height, flower colour, collector number and date, along with the species name and the indication “n. sp.”. The specimen HBG522811 was chosen here as the lectotype , following Borges et al. (2018) guidelines for lectotypification of Ule’s collections. This specimen is well preserved and morphologicaly representative, with abundant reproductive material, facilitating the comparison with the protologue description.
