Description

[edit]

Vegetative characteristics

[edit]

Barclaya hirta is an aquatic plant with villous, stoloniferous, slim, 2–5 cm long, and 0.5–1 cm wide rhizomes. The 10-15 petiolate, rounded to ovate leaves with an obtuse apex are 5–10 cm long, and 4–8 cm wide. The petioles are 5–20 cm long.[2] The leaves exhibit brownish pubescence.[3]

Generative characteristics

[edit]

The nocturnal, 4 cm wide flower is attached to a 5–20 cm long peduncle. The outer tepals are 2.5–3 cm long, and the 6-8 inner tepals are 2 cm long.[2] The androecium consists of 30-40 stamens.[3] The stigmatic cup has 7-9 carpellary appendages. Fruits were not observed.[2]

Cytology

[edit]

The diploid chromosome count is 2n = 36.[2]
