Flowering plant 25–32 cm tall. Leaf 8–17 cm long, 6–10 mm wide. Flowers solitary (rarely 2); perianth segments 2–5 cm long, creamy yellow to greenish yellow; lateral sepals and petals divergent, drooping; sepals flattened at base, 2.5–4 mm wide, tapered to a filiform, clubbed tail, clubs 3–10 mm long, with reddish or purplish, contiguous, sessile glands; petals shorter than sepals, flattened at base, tapered to long acuminate apex, rarely shortly clubbed. Labellum more or less flat, curved forward with apex recurved, lamina ovate, very obscurely 3-lobed, 9–11 mm long and 7–9 mm wide (when flattened), pale yellow (very rarely reddish towards apex); marginal calli on lateral lobes club-shaped, to 1.3 mm long (very rarely absent), diminishing in size to a crenulate or entire mid-lobe; lamina calli in 4 or 6 rows, extending over half of lamina, narrow, foot-shaped, to 1 mm long at base of lamina, decreasing in size towards apex. Flowers Sep.

GipP, Gold, Wim. Also SA. Extremely rare in Victoria, known only from 4 localities between Bendigo and Dimboola where it grows on sandy soil in Eucalyptus leucoxylon woodland.

Caladenia xanthochila is similar to C. stellata from southern NSW and eastern SA. It differs from that species in the labellum mid-lobe not usually being dark red and having almost entire margins, and the sepal clubs having contiguous glands.
