Crassula basaltica

A tiny Sicilian Crassula described by Brullo and Siracusa in 1994, named for the basalt substrates of its habitat. Like the related small annual Crassula of the Mediterranean it is presumably a winter–spring ephemeral that completes its life cycle before the summer drought.

Where it grows wild

No habitat notes were reachable. The name points to basalt, and Mediterranean relatives in the Tillaea group grow in thin soil and seasonally wet hollows on rock outcrops in full sun.

No elevation data; the climate point used is at about 330 m in south-central Sicily.
