Nomenclatural notes: —In the original description of Mitreola spathulifolia, Fang et al. (1995) indicated the duplicate of the collection Fang et al. 3146 at GXMI as a holotype, and its duplicate at GXNM as an isotype. However, we have found four duplicates of Fang et al. 3146 in GXMI matching the detailed description and specimen label information included in the protologue. These duplicates should be treated as syntypes in accordance with Art. 9.6 of ICN ( Turland et al. 2018). We selected the specimen with the barcode GXMI 050420 as the lectotype following Arts. 9.3 and 9.11 of ICN ( Turland et al. 2018) as it represents best the species, having an intact well-developed stem and numerous inflorescences. The other specimens at GXMI ( GXMI 050418, GXMI 050419, GXMI 050421), as well as the one at GXNM (not seen), are isolectotypes. Of them, the specimen GXMI 050418 has been labeled in shed. as a “ holotypus ” during or after preparation of the protologue; the plant in this specimen has only the distal portion of the stem.
