Commelina ensifolia R.Br.

The species grows as a prostrate herb, producing roots from the stem at the nodes.[1] Flowers are bright blue with three petals, however one petal is much smaller than the others, often producing an appearance of two petals. The species prefers moist soils, but has a broad natural range, extending from coastal monsoon forest to the arid central deserts where it grows as an ephemeral following favourable rains.[1][2][4] The species has been eaten as a green vegetable by Aboriginals. European settlers also ate the plant to prevent scurvy, giving rise the common name of scurvy grass.[5]

The species is a minor weed in some parts of its natural range.[6]
