Smooth-lipped Spider Orchid
Caladenia integra
Synonyms
- Arachnorchis integra
- Phlebochilus integrus
Notes
While locally common, the Smooth-lipped Spider is restricted to the southern Wheatbelt region of WA where the orchids grow in scattered populations in Sheoak woodland at the base of granite outcrops. The peak flowering season is mid spring, slightly later than that of the closely related Fringed Mantis Orchid (Caladenia falcata) which is found over a similar geographic range.
The Smooth-lipped Spider Orchid is readily distinguished from the Fringed Mantis Orchid by its smooth labellum edges and generally taller plants. Where the two species grow together, the Smooth-lipped Spider Orchid usually flowers a few weeks later than the Fringed Mantis Orchid, although there is significant overlap. The colour of the petals and sepals is variable and ranges from green to cream-coloured and dark red.
