Plectorrhiza tridentata
Common tangle orchid
This epiphyte generally grows on twigs on trees in rainforest or moist forest around Brisbane. Its roots form a tangled mess giving rise to its common name of tangle roots.
This orchid will grow up to 20 leaves about 10 cm by 1.5 cm on its stem. The flower racemes grow to about 10 cm long with up to 15 flowers. Each flower is about 8 mm across with white labellum and green or brown petals and sepals.
The only other similar orchid is Plectorrhiza brevilabris which does not have the finger like projection above the labellum and has a prominent descending white spur.
