Dipodium pulchellum is a leafless mycoheterotrophic orchid that is endemic to north-east New South Wales and south-east Queensland in Australia.

Description[edit]

For most of the year, plants are dormant and have no above-ground presence. Below the ground lie fleshy roots. Flower spikes between 27 and 90 cm in height appear in summer.[3] These racemose inflorescences have 5 to 40 pink flowers with darker blotches. The sepals and petals are more or less straight and the labellum is dark-reddish pink with mauve hairs.[4]

Taxonomy[edit]

The species was formally described in 1987 by Australian botanists David Lloyd Jones and Mark Clements. The type specimen was collected in the Tallebudgera Range in Queensland.[1]

Distribution and habitat[edit]

Dipodium pulchellum occurs in south-east Queensland and north-east New South Wales near Wardell, Grevillia and Tia Falls.[4]

Ecology[edit]

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

Cultivation[edit]

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