The scientific or botanical name of a flower depends on the specific type of flower and its species. For example, the genus for the rose is Rosa, and it belongs to the family called Rosaceae.
However, there are over 100 different species of roses. Each species has its own botanical name, such as Rosa hybrid, Rosa ‘Santana’ and Rosa palustris. The scientific or botanical name is combination of the genus and the species type.
Likewise, the orchid family consists of different genera and species. The different genera include Cymbidium, Dendrobium and Phalaenopsis. One particular type of orchid is the Phalaenopsis schilleriana. For this flower, the genus is Phalaenopsis and the species is schilleriana.
From these examples, it is evident that there are many different scientific names for other flower families, such as the aster, lily, buttercup, chrysanthemum and many others.
