Dipodium stenocheilum, commonly known as tropical hyacinth-orchid,[3] is a leafless mycoheterotroph orchid that is endemic to northern Australia.

Description

For most of the year, plants are dormant and have no above-ground presence. Below the ground lie fleshy roots. Flower spikes between 40 and 120 cm in height appear between November and March.[3]

Taxonomy

The species was formally described in 1927.[1]

Distribution and habitat

Dipodium stenocheilum occurs in the northern parts of Western Australia, the Northern Territory and Queensland.[4][5]

Ecology

Pollination of this species, as for all species in the genus, is by native bees and wasps.[3]

Cultivation

No leafless species of Dipodium has been successfully maintained in cultivation due to the inability to replicate the association with mycorrhizal fungi in a horticultural context.[3]
