Fragrant Leek-orchid  |  

Prasophyllum suaveolens

Status: Endangered on the EPBC Act list

The fragrant leek-orchid produces a single, erect, hollow and tapering leaf. The flower stem emerges through a slit in the leaf, producing up to 15 very small, greenish to reddish brown flowers. Endemic to the basalt plains of south-western Victoria this species is mostly found from inland areas growing in grasslands and open grassy woodlands, on poorly drained, red-brown soils. In 2010, eight populations of fragrant leek-orchid were known with around 1500 individual plants, a much larger number than the 200 individuals recorded in 2006. Weed invasion is a threat to this species.

    Fire Frequency known Too infrequent fire; or other form of disturbance such as current slashing; may pose a threat by not reducing the accumulation of grasses such as kangaroo grass.

    Too frequent fire may pose a threat by altering the habitat; removing organic surface materials and negatively impacting pollinators and mycorrhizal agents.
