黃花藺

植物簡介

It is an erect, perennial, aquatic herbaceous plant, growing up to 50–120 cm tall. The leaves are lime-green or bluish-green, smooth and hairless and arranged in a basal rosette. The leaf blades are either ovate or near circular in shape, with 7–17 main nerves and numerous secondary nerves running in parallel. The petioles (leaf stalks) are up to 85 cm long, thick and triangular in cross-section with many air chambers. The inflorescence is an umbel (a type of inflorescence in which the flowers arise from a common point on the inflorescence stalk) with 3–15 yellow flowers with cream margins. The peduncle (inflorescence stalk) can grow up to 90 cm in length, standing erect when flowering and curving downwards when fruiting. The flowers open in the morning only for a few hours. The fruit is compound capsule (a type of dry, dehiscent fruit), which is globose or broadly ellipsoid in shape and contains numerous dark-brown, horseshoe-shaped seeds. The seeds are propagated by water.
