Notes:—Some recent studies (Martos et al. 2014, Bone et al. 2015) suggested merging Geodorum under Eulophia, which was recently undertaken after proposing to conserve Eulophia against Geodorum by Chase et al. (2021a, b). While transferring Geodorum densifloum (≡ Limodorum densiflorum), as the name Eulophia densiflora Lindley was already taken, the next available synonym was used, namely, Malaxis cernua Willdenow, to make the new combination Eulophia cernua (Willd.) M.W.Chase, Kumar & Schuit. However, they overlooked the publication by Hsu & Chung (2016) where this combination was already proposed - Eulophia cernua (Willd.) T.C.Hsu. Both names, Geodorum densifloum and Malaxis cernua were based on the same type, making the latter combination illegitimate following article 52.1 (Turland et al. 2017). Hence, we suggest Eulophia picta as the next available name for this entity.
