Botanic information
Leaf: The 1 to 3 broad-lanceolate to ovate-lanceolate leathery dark green leaves have an acuminate apex and the base forms a sheath around the stem.

Flower: The 2-lipped labiate flower have a small white upper hood and 2-larger spreading lobed lower petals. It is surrounded by large overlapping petal-like pointed bracts. The flowers are arranged in a condensed spike that is held just above the clump and appear during early summer.

Fruit: The small 3-valved capsule is oblong and slow to open. The elongated capsule contains small seeds that are viable but the plant is commonly reproduced vegetatively.
