The channelled, narrow leaves of Chlorophytum saundersiae grow tufted from the base at ground level. The leaves are erect, curving out, nearly flat and green, about 50 cm long and 1 cm wide.

The inflorescence is a crowded, long and narrow raceme or panicle at a stem-tip, often producing more than one flower per node. The white flower on a jointed pedicel has six spreading to somewhat reflexed, pointed tepals. Each flower lasts for about a day.

The large, oblong, yellow anthers cluster over the flower centre. The white style from their midst is longer, the ovary from which it emerges superior.

The fruit is a three-sectioned capsule, the seeds thin and black (Pooley, 1998; iNaturalist).
