Pelargonium ochroleucum, tuberous pelargonium
The flowers are born in an unusual way within the inflorescence: the greenish-yellow posterior petals are directed to the centre of the pseudo-umbel and the white anterior ones to the periphery, giving the appearance of a daisy. This arrangement of the flowers, called a pseudanthium (all the flowers in the pseudo-umbel together give the appearance of a single flower), probably plays a role in the pollination biology of the species.
