At the Poipu Bay area of Kauai, most hotel lawns are seashore paspalum. This lawn at the Sheraton Kauai is a typical example.

Under the trees, though, closer to the beach, a different species grows. 

This is manilagrass (Zoysia matrella). It is growing under the trees and creeping onto the rocky beach.

In fact, it even grows right on the beach. The manilagrass is salt tolerant, drought tolerant, and has a finer leaf blade than the seashore paspalum. One might expect to see the seashore paspalum growing closer to the ocean, but in this case, it is the manilagrass that grows right at the water's edge.
