Habenaria cornuta sepal arm domination

The long green floral arms that curve inwards, embracing air, are the lateral sepals of these Habenaria cornuta flowers, growing in a lax spike. These sepals are thinly cylindrical, unlike the dorsal one that is short, a shallow, elliptic bowl reflexed back above the rest of the flower.

H. cornuta flowers are fragrant, probably more so in the evening (Pooley, 1998; www.orchidspecies.com).
