Flowering: 1-10 flowers to 15mm wide, facing away from stem. Hood leaning forward, small tapering tip; petals flanged; lateral sepals drooping, brown-tipped tips incurved, to 4mm; lip yellowish with black stripe, drooping.

Growing Conditions: Moist to well drained heavy to loamy soils in closed mountain forests, open forests and scrublands. Semi shade. Plants tend to grow close to eucalypt trunks.
