Similar to D crumenatum but the narrow leaves recall D singaporense of the section Aporum but has a very differnet lip shape. D lawiense in the positiom of the much longer bulbous stem thickeneing and in the character of the lip. In vegetative appearance D tridentatum is much like D linearifolium but differs widely in the flower structure.
