Full descriptions, analytical plates and notes on nomenclatural history, affiliations, occurrence, ecology and global conservation status are provided. Type status for Calanthe × dominyi is validated. In addition, the taxonomy of Vanilla shenzhenica is reviewed, leading to the recognition of distinct morphological characters that warrant its separation from V. somae, with which some authors have considered it synonymous.
