Rubidium: geological information. Rubidium is far too reactive to be found as the free metal in nature. It is relatively rare, although it is the 16th most abundant element in the earth's crust. Rubidium is present in some minerals found in North America, South Africa, Russia, and Canada. It is found in some potassium minerals (lepidolites, biotites, feldspar, carnallite), sometimes with caesium as well.
Hibiscus tiliaceus is a common coastal plant in Eastern and Northern Australia, Oceania, Maldives, South Asia, and Southeast Asia. It has become naturalized in parts of the New World, such as Florida, Puerto Rico, and the Virgin Islands. It is uncertain if the species is native to Hawaii, as it may have been introduced by the Polynesians. Hibiscus tiliaceus can be found at elevations from sea level to 800 m (2,600 ft) in areas that receive 900â2,500 mm (35â98 in) of annual rainfall.
