Flowering plant 10–25 cm tall. Leaf 8–12 cm long, 8–12 mm wide. Flower solitary; perianth segments 2.5–4 cm long, greenish cream to yellowish, sometimes with red median stripe; sepals 3–4 mm wide at base, tapered to filiform, narrowly clubbed tails, club 8–15 mm long, with dark-coloured, sessile glands which are mostly tightly packed and contiguous; lateral sepals divergent, spreading to deflexed; petals spreading to deflexed, shorter than sepals, flattened at base, tapered to long acuminate apex, sometimes with small, glandular, clubbed section shortly below tip. Labellum curved forward with apex recurved and lateral lobes curved upwards, lamina ovate, obscurely 3-lobed, 10–12 mm long and 7–9 mm wide (when flattened), glossy red distally and along centre to base, proximal flanks pale yellowish-green; lateral lobes entire around curved base, then with marginal calli linear to triangular, mostly to 1 mm long (sometimes much smaller, rarely to 1.5 mm), diminishing in size towards entire or slightly irregular mid-lobe; lamina calli in 4 or 6 rows, not reaching the bend, linear or foot-shaped, to 1.5 mm long at base of lamina, decreasing in size towards apex. Flowers Nov.–Jan.
EGL, EGU, HNF, HSF, MonT, NIS, SnM, VAlp. Also NSW, ACT. Localised to higher montane areas of eastern Victoria where it grows among shrubs on slopes and ridges in woodland on well-drained soils.
Caladenia montana is similar to, and could be confused with, a few other eastern species; see C. oreophila, C. peisleyi, C. osmera and C. australis. It is also difficult to distinguish from the NSW species C. fitzgeraldii.
When the marginal calli of the labellum are particularly small and blunt, C. montana resembles C. clavigera, but differs from that species in having thicker and longer clubs, and a broader labellum with narrower lamina calli. Caladenia montana is known to hybridize with C. clavigera.
