Book 1 Chapter 9, No Spoilers: Questions about the Map

I am in Gardens of the Moon in ch9 at the point where Lorn and Dujek discuss the spring landing of new troops to Genabackis and I am confused with the geography here.

They say they will land at Nisst and that it is hard to hold Fox Pass. Neither of these places exist on the map.

Then Dujek says he wants troops to land on the east coast south of Apple (fine, that makes sense)....but also on the west coast to Tulips (Tulips is on the east coast south of apple..........???).

Can someone clear up the confusion?
