User's notes

virtually prostrate, in clumps almost covering entire area. During wet periods this area fills with water (shallow) which drains very slowly. Currently has been dry for many months.

Do any of the leaves have black patches on them?

No black patches. Given the location, it could well be exotic. Easy to revisit if you want more details.
