Disa klugei is a slender terrestrial orchid that grows leaves and flowers annually from its perennial tuberous rootstock.
The flower spike of about 7 cm in length is lax, sparsely flowered. It carries about twenty flowers (up to 26), each about 8 mm in diameter.
The floral bracts, pushed outwards by ovaries spreading away from the stalk, in picture look very different to the erect, narrowly pointed stem leaves below the flower spike. The tips of these bracts have turned brown even on the unopened buds at the top of the inflorescence in the photo.
Flowering happens in late spring through summer (iSpot; www.orchidspecies.com).
