2. Agarista angustissima Taubert (1893: 513)

≡ Leucothoë angustissima (Taub.) Sleumer (1959: 451) .

Type:— BRAZIL. Minas Gerais: Pinheiro, nr. Biribiri , 26 Mar 1892, A.F.M. Glaziou 19582 (lectotype P00715901 , image!, here designated; isolectotypes BR0000006996079 , image!, F0055214 , fragment!, F0055215 !, G00390579 , image!, IAN094294 , image!, K000494457 , image!, MO0345490 !, NY00008172 !, P00715900 , image!, P00715902 , image!; the former lectotype B †, designated by Sleumer 1959: 451).

Note:—The remaining original material of Glaziou 19582 consists of 10 specimens (BR0000006996079, F0055214F, F0055215F, G, IAN094294, K000494457, MO-345490, NY00008172, P00715901, P00715902). We also consulted the herbarium R, which has many Glaziou type specimens, nonetheless, no duplicate of this collections was found. Taubert (1893) published A. angustissima with the collection Glaziou 19582 as the type of the species. According to the TL II ( Stafleu & Cowan 2022), the collection numbers Glaziou 3267-22770 were deposited in B and the collection Glaziou 19582 deposited in there was destroyed by the fire.

Sleumer (1959) included the species of Agarista in Leucothoë sect. Agastia and combined the name A. angustissima as L. angustissima , assuming the B† specimen as “ Holotype ”, and indicated the location of some isotypes (BR, K, NY, P), beyond the so-called “ Holotype fragment” at F. Judd (1984, 1995), who reestablished Agarista at generic rank, kept the designation of the holotype at B†, and indicated additional isotypes at G and MO. According to the Art. 7.11, Ex. 13 of the ICN (Turland el al. 2018), Sleumer (1959) designated the B† specimen as the lectotype. The remaining duplicate specimens became isolectotypes. As this lectotype was destroyed, according to the Art. 9.11 a new lectotype must be designated as its substitute.

Therefore, we herein revised the isolectotypes and designate the specimen from P ( P00715901 ) as the lectotype of the name Agarista angustissima because it is well preserved, presents fruits and flowers, and is in accordance with the protologue. Furthermore, the label contains the correct information about the collection. Additionally, this material is available digitally in speciesLink ( SPECIESLINK, 2022) and the digital herbarium database from P ( MNHMP 2022 ).
