Sepals and petals basally fused, forming a short tube, subsaccate along fusion with the column foot. Lip lobed or entire, sessile-cuneate. Column arcuate, with a foot; pollinia four.


From the Greek didymos, meaning twin, and plexis, meaning plaiting, referring either to the folding caused by the fusion of the dorsal sepal and petals or to the pair of column wings.
