Q.
A student observed 34 inflorescences in Bougainvillea and 42 inflorescences in Poinsettia. Find out the number of flowers
in Bougainvillea and the number of female flowers in Poinsettia, respectively.
In Bougainvillea, inflorescence is a dichasial cyme,
where medially situated peduncle itself finishes in a flower
and bears two lateral floral branches at the base of its
origin. Hence, in 34 inflorescences, the number of flowers
is 102. In Poinsettia, inflorescence is cyanthium type. In
this, a single central female flower remains surrounded by
numerous male flower in a cap formed by the fusion of
involucre, so in 42 inflorescences, the number of female
flower is 42
