It grows on exposed rocky slopes in full sun where there is no soil.
From Siddarabetta, near Bangalore.
It was completely dry when I collected a small piece.
After bringing it home, i immersed it in water and in three hours it seems to have revived completely.
It is probably S. wightii - but I have to confess I never yet troubled to learn the difference between S. wightii and S. indica (longipila) both of which are in S. India - could you just check out the difference in case it is indica? It can only be one of those two very similar species.
