I'm questioning the accuracy of the botanical drawing. Look at the differences in the top view of the leaves in the drawings, and compared to your plant Myriam. The boxed sections of veins going up the outer edges of the leaves aren't shown to go as far up the leaf, nor are they shown in detail on the top view of the leaf in the drawing. This is apart from any leaf shape or venation variation there may be.
Open the top views in new windows and place side by side, you will see a big difference.
