Manfreda justosierrana García-Mend. (2011: 748)

≡ Agave justosierrana (García-Mend.) Thiede (2012: 94)

Type ( lectotype designated here):— MEXICO. Guerrero: Municipio Leonardo Bravo, 4 km al E de Los Morros, 7 km al SE de Filo de Caballo, carretera a Xochipala , 1940 m, 11 nov. 1998, A. García-Mendoza, A. Gutiérrez, S. Franco y A.Castañeda 6739 (MEXU00936610!, isolectotype MEXU00936618!).

Distribution: —Endemic to the state of Guerrero, Mexico ( García-Mendoza 2011).

Note:— Manfreda justosierrana García-Mendoza (2011: 748) was described on the basis of one collection from Mexico (Guerrero): A. García-Mendoza, A. Gutiérrez, S. Franco & A. Castañeda 6739 (MEXU) as the holotype [first-step]. Later, Thiede (2012) published a new combination, Agave justosierrana (García-Mend.) Thiede (2012: 94) , when transferring Manfreda Salisbury to Agave , but without indicating any of the specimens that might serve as a type. We located two duplicates in the same herbarium (MEXU barcodes 00936610 and 00936618), but the protologue did not indicate which of the two is the holotype. Therefore, they are syntypes, and a lectotype must be chosen (According to Art. 8.3, & 9.17; Turland et al. 2018). We designate one of the sheets kept in MEXU (barcode 00936610) as the lectotype [second step]. The selected sheet is completer and more well-preserved that displays all the morphological diagnostic features in agreement with the protologue.
