Morphology Reproductive morphology Flowers
Flowers single, in dense cylindrical spikes from the rosettes, spikes sessile, unbranched or with branches from base of the terminal spike; peduncles with scattered to imbricate scale-like sterile bracts; fertile bracts imbricate, spirally arranged, scale-like, persistent, without or with indistinct midrib; bracteoles 2, narrowly ovate-elliptic.
Morphology Reproductive morphology Flowers Calyx
Calyx divided almost to the base into 5 sepals; dorsal much wider than the rest, the two lateral slightly wider than the two ventral which are united higher up than the rest.
Morphology Reproductive morphology Flowers Corolla
Corolla weakly 2-lipped, sometimes cleistogamous; tube linear, cylindric, widened into a short throat; lower lip 3-lobed, lobes often bifid.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 2 (rarely 4 or 2 plus 2 staminodes), included in the throat; filaments short; anthers 2-thecous, thecae at same height, oblong or broadly elliptic, without basal appendages, connective produced apically.
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2-locular, with 6–10 ovules per locule; stigma oblong-spathulate or rounded, entire or 2-lobed.
Morphology Reproductive morphology Fruits
