On the other hand, some scientists are acquainted with botany and learned in horticulture.

They know every plant and its value, but they care little about tidiness.

Cut flowers are feminine frivolities in their eyes, and they count nosegays as childish gauds, like daisy chains and cowslip balls.

They are not curious in colours, and do not know which flowers are fragrant and which are scentless.

For them every garden is a botanical garden.
