Threat status:Victoria: rare (r)

Flowering plant very slender, 9–22 cm tall. Leaf linear, 3–10 cm long, c. 1 mm wide. Flowers 1 or 2, mostly white; perianth parts similar to those of C. carnea except for following features: sepals and petals 7–10 mm long, conspicuously green striped on outside, lateral sepals often united at base and more or less parallel throughout; labellum without red bars on inside, apex orange, broadly toothed (teeth about as wide as long); column and wings both relatively broad, without red bars. Flowers Sep.–Oct.

EGL, GipP, Strz, WPro. Also Tas. Grows in damp coastal to near-coastal heaths or heathy woodlands east of Melbourne (e.g. Cranbourne, Yarram, Cape Conran, Mallacoota) on well-drained sandy soils.

Caladenia aurantiaca is similar to C. catenata, but the former has shorter perianth segments, more or less parallel lateral sepals, and a labellum with a smaller mid-lobe and short, broad teeth on the apical ends of lateral lobes. Caladenia aurantiaca could also be confused with C. alata, but the latter has either pink or white flowers with free and spreading perianth segments and reddish stripes on the labellum and column.
