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.
