There are two lateral sepals and one dorsal sepal. The dorsal sepal is long and the lateral sepals are slightly narrower. Sepals 5, gamosepalous, tube short, 5 lobed, obtuse, glabrous, imbricate, odd sepal is anterior. These are flaps of tissue, running from the perianth tube above the sepal. The posterior sepal is fused with the pedicel to form a hypanthium (nectary tube). The flower have bell-shaped sepal split into five lobes, and around 20 stamens. The dorsal sepal and petals are fused, forming a hood or "galea" over the column. The back of the dorsal sepal has many glandular hairs. The dorsal sepal and petals overlap to form a hood over the column. The lower sepal is lanceolate and about long by about wide. The dorsal sepal points downwards and is pressed against the column. The upper sepal and the two lateral petals form a hood. The dorsal sepal is long and about wide. The three, sometimes reduced, petals stand upright, partly behind the sepal bases. There are six fleshy nectar glands at the base of each sepal which attract pollinators.
