(pronounced: mye-KROH-tiss)


Diurideae subtribe Prasophyllinae


Colony-forming terrestrials arising from a globose or cylindric tuberoid, the tuberoid surmounted by a ring of roots. Stems erect, emerging from a long, tubular leaf sheath. Leaves solitary, linear-filiform. Inflorescences erect, scapose, densely-flowered racemes. Flowers minute, resupinate. Sepals and petals free, the petals frequently appressed to the dorsal sepal. Lip sessile, unlobed, with one or two series of callus. Column short, winged; pollinia four, in two unequal pairs.


From the Greek mikros, meaning small, and otos, meaning ear, from the small membranaceous auricles on the column.


A genus of 14 species ranging from China and Japan to Australia, New Zealand and New Caledonia.
