Notes: —In his treatment of Microlicia species, Chamisso (1834) divided the text in two parts; in the first, the author listed species of Microlicia considered by him as “not good” Microlicia , i.e., the species that do not fit in his concept of the genus, with anthers elongated and long rostrate, frequently herbaceous. Chamisso (1834) called these species “Spuriae”, that later were correctly placed in Acisanthera and Comolia by Triana (1872). In the second part, Chamisso (1834) listed species that he considered to belong to Microlicia , “ Microliciae Don. Genuiae ”, i.e., species with ovateoblong anthers, shortly rostrate and frequently subshrub. For some of these species, he appended the letter N. (nostrus, a, um) when it was considered a new species. The species no. 7 was listed as “ Microliciae species insignis est ” (i.e., a remarkable species of Microlicia ) followed by the name Melastoma Lhotzky et Manso , Flora de Matto Grosso Cujabensis no. 52. This work has never been located. Chamisso (1834) presented a short description of this plant, but he did not explicitly name it. However, in the index the epithet “insignis” is listed, added by the editor Diederich Franz Leonhard von Schlechtendal (1794–1866) (see Heuchert et al. 2017). Since then, the name M. insignis has been used in several herbaria, but always with some confusion regarding to its authorship.

Although there are three sheets of M. chloracea at P, one of them (P02297821) was added in 1892 and the other one (P02297822) was acquired in 1904 (see Bureau 1904; Le Bras et al. 2017). Therefore, we conclude the sheet with a short description handwritten by Naudin is the holotype of M. chloracea . Naudin (1849) cited Gardner 3156 in the protologue of M. depauperata without providing additional information. There are three sheets at P; one belonged to E. Drake’s herbarium, donated to P in 1904 (see Bureau 1904; Le Bras et al. 2017). We designated as lectotype of M. depauperata the sheet with a short description and drawing made by Naudin.

Cogniaux (1883) described M. francavillana based on two sheets and Gardner 3732bis from BR is designated as lectotype because it better represents the species description, clearly showing the characters mentioned in the protologue. Furthermore, in the same work, Cogniaux (1883) indicated Pohl 1220 as original material from M. pallida , which is here lectotypified and synonymized under M. insignis .

When describing M. goyazensis, Pilg. in Engler (1903 [1904]) referred to one collection made by Glaziou (Glaziou 21250) in Brazil, deposited at B, but destroyed during World War II (see Hiepko 1987). The specimen from BR is designated here as lectotype and the remaining as isolectotypes.

In the original description of M. insignioides, Hoehne (1922) cited two specimens. The sheet F.C. Hoehne 2411 corresponds perfectly with the protologue, and it is selected herein as lectotype of M. insignioides .

Ducke (1922) cited only one specimen (Ducke s.n. [“N. 15616”]) in the protologue of M. paraensis . In this work, he mentioned the number of the herbarium of the Museu Paraense [Museu Paraense Emílio Goeldi – MG]. This specimen is in the records of the MG herbarium, but, despite several searches, it was not found in the collection. The sheet cited in the protologue was taken by E. Adolpho Ducke (1876–1959) to RB (A.S.B. Gil, pers. commun.).

Hoehne (1922) assigned the name M. insignis var. cearensi s to Ducke and mentioned that [RB] n° 10.841 (Ducke s.n. [MG 15.616]) was recognized as a new species by the collector. Ducke s.n. [MG15.616] is the original material from M. paraensis . So, M. insignis var. cearensis is treated as nomen nudum according to Article 38.1 ( Turland et al. 2018).
