Ficus elastica prefers bright sunlight but not hot temperatures. It has a high tolerance for drought, but prefers humidity and thrives in wet, tropical conditions. Ornamental hybrids (such as Robusta) have been derived from "Ficus elastica" with broader, stiffer and more upright leaves than the wild form. Many such hybrids exist, often with variegated leaves. "Ficus elastica" yields a milky white latex, a chemical compound separate from its sap and carried and stored in different cells. This latex was formerly used to make rubber, but it should not be confused with the Pará rubber tree, the main commercial source of latex for

That specimen may have been from the same tree as Henne's specimen, (as the island is so small). Banks' plant was named in 1901 after the Endeavor's artist Sydney Parkinson, (Ficus parkinsonii). However, this name fell out of favour as "Ficus henneana" was already named in 1868. The specific epithet "superba" is from Latin referring to "outstanding" or "superb". The plant has had other scientific names, such as "Ficus gracilipes", "Ficus pritzelii" and "Urostigma superbum". The tree is semi
