The 5-6 cm wide diurnal flowers are attached to 10-15 cm long peduncles. The flowers have 40–50 anthers. The gynoecium consists of 9 carpels. The globose, 2 cm wide fruit bears ellipsoid, spiny, 2 mm long seeds. The floral fragrance has been characterised as pungent, fermenting, and as smelling of rotten meat.[2]

Cytology[edit]

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

Reproduction[edit]
