Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Threat status:Victoria: endangered (e)

Flowering plant 25–35 cm tall. Leaf 8–15 cm long, 10–15 mm wide. Flowers 1 or 2, fragrance sweet; perianth segments 4–8 cm long, creamy white, yellowish or pink with reddish-brown glandular tips and central stripe, lateral sepals and petals drooping; sepals flattened at base, 2–5.5 mm wide, abruptly tapered to a long tail densely covered in glandular hairs; petals somewhat shorter than sepals, but otherwise similar. Labellum curved forward with apex recurved and lateral lobes erect, lamina ovate, obscurely 3-lobed, 12–20 mm long and 7–11 mm wide (when flattened), yellow with deep reddish margins and calli; margins of lateral lobes fringed with linear calli 1–2 mm long, margins of mid-lobe with shorter calli becoming tooth-like near tip; lamina calli in 4 or 6 rows, extending well onto mid-lobe, narrow, foot-shaped, to 1.5 mm long at base of lamina, decreasing in size towards apex. Flowers Sep.–Nov.

Once broadly applied to a widespread species in south-eastern Australia, the name Caladenia patersonii is currently of uncertain application. As circumscribed here, it refers to plants found in Tasmania and eastern coastal Victoria. Some specimens at MEL from inland Victoria have yet to be adequately classified. See also C. fragrantissima and C. orientalis.

Caladenia echidnachila from Tasmania appears to be based on a petaloid development of the labellum in some plants of C. patersonii and therefore is not worthy of taxonomic recognition.
