Threat status:Victoria: rare (r)

Flowering plant 20–60 cm tall. Leaf 15–30 cm long, 8–20 mm wide. Flowers 1 or 2; perianth segments 5–10 cm long, pale greenish-yellow, lateral sepals divergent, spreading to drooping, flattened at base, 5–10 mm wide, abruptly tapered to a filiform tail (not distinctly clubbed) with relatively widely spaced, sessile glands; petals spreading to drooping, shorter than sepals, flattened at base, tapered to long acuminate apex, sometimes glandular. Labellum curved forward with apex recurved and lateral lobes erect, lamina ovate to ovate-lanceolate, obscurely 3-lobed, 14–23 mm long and 10–12 mm wide (when flattened), greenish-yellow to pale yellow, rarely maroon in distal half; marginal calli on lateral lobes linear, to 3.5 mm long, those on mid-lobe shorter and more tooth-like; lamina calli in 4 or 6 rows, extending onto base of mid-lobe, narrow, foot-shaped, to c. 2 mm long at base of lamina, decreasing in size towards apex. Flowers Dec.–Jan.

EGL, EGU, GipP, Glep, HFE, HNF, HSF, OtP, OtR, VAlp, VVP. From coastal to near-coastal habitats through to low altitude mountain forest (e.g. Mt Dandenong area), formerly common near Portland where now rare and localized, and possibly extinct in the Lorne and Marlo areas. Grows among shrubs in stunted coastal scrub, often in sandy soils, or in open montane forest with a grassy understorey.

Caladenia flavovirens differs from all other greenish yellow flowered Caladenia species in having sepal tails not distinctly clubbed and with relatively widely spaced (not densely crowded), sessile glands. See also notes under C. aestiva.

The distribution of C. flavovirens is somewhat obscure due to confusion with C. aestiva.
