Plants are winter deciduous, solitary or dividing to form small clusters, pendent, from sheer cliffs. Bulbs are rounded to egg-shaped, 30–40 × 20–30 mm, the bulb scales white, fleshy and somewhat transparent. The outer scales drying greyish, bearing dark transverse ridges towards the neck. The roots are whitish, less than 1 mm in diameter. The leaves 4 or 5, appear more or less at the same time as the inflorescence, oblong and drawn to a point, 700–820 × 25–35 mm, hanging and spirally curved, semi-succulent, soft and flaccid, the upper surface channelled, rounded at the apex, the surface greyish green with an entire margin.

Inflorescence is 200–300 mm, pendent, 1 or 2 per plant. The raceme is conical, 80–140 × 55–70 mm long (multi-flowered), with a stalk 120–150 mm long, about 5 mm in diameter at base and inflating to 10–15 mm in diameter at the centre, tapering again in upper half, and same colour as the leaves. The bracts are conspicuous, white, clasping pedicel and channelled; older bracts remain functional until inflorescence expires; lower bracts 45–60 × 6–7 mm, becoming smaller upwards. Lower pedicel 12–17 × 0.7–1 mm, becoming shorter upwards, the lower pedicels lengthening in fruit to about 30 mm. The flowers are densely arranged (35–50), each bearing 5, spreading, white petals, 20 mm in diameter, sweetly scented. The stamens are 8 mm long The ovary yellowish green, ridged, tapering at the apex, 4.5 × 4.5 mm. The style 3 mm long, extending to 5 mm when mature, , erect, white. The fruiting capsule is 7–9 × 7–9 mm. The seed is flattened, half-moon shaped, angular, about 4 × 2 mm, black, with a shiny surface.

Albuca lebaensis flowers in winter (June–August) and during which time the leaves becomes dormant. Seeds are dispersed by wind in spring (September onwards).
