Q4. 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.
Solution
In Bougainvillea, inflorescence is dichasial cyme, where medianly 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, inflorescences is cyathium, in which a single central female flower remains surrounded by numerous male flowers in a cup formed by the fusion of involucres, so, in 42 inflorescence, the number of female flowers is 42.
