Distribution and ecology: — Notylia platyglossa ( Figure 1 ) is a species that is endemic to South America, which occurs in Bolivia, Brazil, Ecuador, Peru and Venezuela ( Tropicos 2024). In Brazil, it occurs exclusively in the phytogeographic domain of the Amazon, in the states of Amazonas, Mato Grosso and Pará (Flora e Funga do Brasil 2024) ( Figure 2 ). Silveira (2008) cited the occurrence of the species for the state of Acre based on the collection of Ule 9264; however, when examining the protologue of the species and the field collection records of Ule (book No. 7, collection numbers 13.321 to 15.585) at MG, it was found that the collection carried out in the Seringal São Francisco on the margins of the Acre River is within the territory of the state of Amazonas. In addition, we make the first record of the species occurrence in the state of Maranhão ( Figure 2 ).

Conservation status: —The EOO was estimated at 5,098,118.584 km 2 (corresponding to “Least Concern (LC)” according to criterion B1) and AOO was 92 km 2 (corresponding to “Endangered (EN)” according to criterion B2), presenting continuous decline in its area of occupation and fragmentation of its habitats located in areas subject to threat (subcriterion B2b (ii,iii, iv)). The record of this species in the Humaitá National Forest is the only one within a conservation unit in Brazil. Therefore, applying the IUCN criteria (2012, 2022), the taxon can be considered EN [B2b (ii, iii,iv)].

Taxonomic discussion: — Schlechter (1914) described N. platyglossa based on the collection E. Ule 9264, though did not inform the herbarium where it was deposited. Herbaria B and HBG are known as the most representative in E. Ule’s collections ( Borges et al. 2018). No corresponding materials have been located in the HBG herbarium collection. Therefore, it is believed that the original material was destroyed in the Berlin herbarium during the Second World War ( Butzin 1978, 1980). The specimen INPA no. 263164 was analyzed and has the characteristics described in the protologue by Schlechter. Therefore, it is herein designated as a neotype because it comes from the type locality. The type designation also follows the recommendations of Borges et al. (2018) for the typification of Ule materials.

Schlechter (1916) described Dipteranthus peruvianus (1916: 187) without informing the protologue of the holotype or herbarium where it was deposited. Schweinfurth transferred the species from the genus Dipteranthus to Notylia (1946: 205). It is believed that the holotype was destroyed in the bombings during World War II ( Butzin 1978, 1980). Therefore, we designate here an illustration published in the protologue by Schlechter, based on the original material, as the lectotype.

Christenson (2001: plate 722) described N. morenoi based on the collection of Vásquez 189 after noting that it had been misidentified in an illustration of N. boliviensis published by Dodson & Vásquez Chávez (1989: t. 264). The holotype was deposited in the herbarium of Roberto Vasquez at his own home, which, after his death, was donated in its entirety to the National Herbarium of Bolivia (LPB). After an intense search for the holotype in the LPB herbarium, it was reported lost/missing by the curatorship. Therefore, we chose here, in accordance with Turland et al. (2018) art. 38 and 38.13, the illustration published by Dodson & Vasquez 1989 based on the original material of the collection of Vásquez 189 as the lectotype.
