Caladenia barbarella, commonly known as the small dragon orchid,[2] is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single broad, hairy leaf held close to the ground and a single greenish-yellow and red flower. It is only known from a small area near the Murchison River.
Caladenia barbarella is a terrestrial, perennial, deciduous, herb with an underground tuber and a single ground-hugging, broad, hairy leaf 3–8 cm (1–3 in) long and 3–7 mm (0.1–0.3 in) wide. The single flower is borne on a stem 8–25 cm (3–10 in) tall and is greenish-yellow with red stripes and 2 cm (0.8 in) wide and long. The lateral sepals and petals are short and hang downwards. The labellum is densely hairy and has a large dark red gland at its highest point. It also has many long purple hairs that are thought to attract pollinators. Flowering occurs in late August and September.[2][3][4]
Taxonomy and naming
Caladenia barbarella was first formally described by Stephen Hopper and Andrew Brown in 2001 from a specimen collected in the Cooloomia Nature Reserve near the Murchison river and the description was published in Nuytsia.[5] The specific epithet (barbarella) is a diminutive form of the Latin word barba, hence meaning "a small beard", but also alludes to a comparison of the sexual deception of this orchid to its male insect pollinators, and the French comic-book character Barbarella.[2][6]
