Upon purchase, the tulips were identified as the "Admirael de Man" on the left and the "Gemarmerde van Goyen" on the right. Tulips are named based on images with annotated names in the so-called tulip books (see illustration of the Jacob Marrel tulip book). However, tulips with the same name often appear to differ significantly in appearance, making this naming unreliable.

Striped, feathery tulips were preferred over plain tulips in the seventeenth and eighteenth centuries. It was not yet known that the stripes were the result of a harmful viral infection. 'Admirael' is the name for the best tulip in the grower's assortment. The term marbled comes from the fact that exceptional tulips were often compared to precious and semi-precious stones, as well as marble.

The tulip gouache in the De Witte Zwaan Collection shows a type that became particularly popular in the eighteenth century, with curled petals and striking details on the flower and leaf, such as dewdrops or damage.
