Generative characteristics
[edit]The flowers are 15–25 cm wide.[5] The four purplish-red sepals are oblong to lanceolate.[6] The 12-20 narrowly oval petals have a rounded apex. The androecium consists of 55 red stamens.[5] The gynoecium consists of 16-21 carpels.[6] The fruit bears 1.85 mm long, and 1.6 mm wide seeds.[5] The peduncle is 116 cm long.[3] The flowers are pleasantly fragrant.[7]
Cytology
[edit]The diploid chromosome count is 2n = 56.[3]
