These photographs (IMG20180920172318.jpg, IMG20180920172408.jpg, IMG20180920172458.jpg, IMG20180920172546.jpg) appear to be of Hibiscus obtusilobus Garcke [Malvaceae].

Hibiscus lobatus.

The epicalyx is absent in Hibiscus lobatus (Murray) Kuntze. However, the attached photographs depict a conspicuous epicalyx.

Hence, H. lobatus (Murray) Kuntze (as suggested by …) can be safely ruled out.
