The species is found growing on open rocks in grasslands of Eravikulam National Park and Mathikettan Shola National Park. The species is restricted in its distribution and has only been found at these two locations so far. The specimens were collected from high-elevation areas (above
) that receive intense sunlight. In Eravikulam National Park, the specimens were found on open rocks near a stream and a waterfall, while in Mathikettan Shola National Park, they were found on open rocks near grasslands.
