The flowers are fragrant, cup-shaped, 15–25 cm broad, with nine thick, creamy white to pink tepals; stamens ca. 210 and ovoid gynoecium with ca. 100 carpels.[1]

gollark: Anyway, I design all my stuff with "extremely flat design".
gollark: I mean, that would fit in the context better, although of course the sentence would remain wrong.
gollark: Yes, the correct term would be "utterly incorrect apioformic beings".
