Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Flowering stem 20–50 cm tall, slender. Leaf 20–50 cm long, tapering gradually to long slender apex; sheath opening well below inflorescence. Flowers 10–50, green, fragrant, erect, in loose spike-like raceme 3–16 cm long; ovary almost ellipsoid, 2–3 mm long, on short pedicel, standing out from stem; dorsal sepal ovate, c. 3 mm long, almost erect, narrowly hooded, apex pointed and slightly recurved; lateral sepals linear-oblong, shorter than dorsal sepal, spreading, recurved to tightly revolute; petals lanceolate and sickle-shaped, shorter than dorsal sepal, basal margins overlapped by dorsal sepal. Labellum reflexed against ovary, more or less oblong, 3–5 mm long, usually constricted about the middle; margins minutely notched, often thickened; apex truncate or notched; lamina with 2 large basal calli and 1 smaller apical one. Column with relatively large auricles.

Apart from those features mentioned in the key, M. rara differs from M. unifolia in having narrower ovary, longer more slender pedicels, a broader, more shallowly hooded dorsal sepal and a narrower labellum often with thickened margins.

Although Clements (1989) and Jones (2006) retain M. oblonga as a species distinct from M. rara, the 2 taxa are here treated as synonymous.
