The flowers of Disa intermedia are white or cream with variable pink-purple markings upon the broad tips of the obovate lateral petals that hide inside the hoods, the dorsal sepals. The hoods are shallowly concave, ovate in shape and tapering to somewhat pointed tips. A long cylindrical and gradually tapering spur grows from the back of this hood, angled down behind the flower.
The sagging lateral sepals are obovate to oblong. Their tips may be rounded or angularly bilobed.
The lip, flanked by the pair of lateral sepals is narrow, broadening to its tip and held slightly higher than the lateral sepals.
The flowers are faintly fragrant. Flowering happens in early summer (www.sntc.org.sz; www.sntc.org.sz).
