Distribution and ecology

S. eminens is confined to the fern forests at higher altitudes on Mt Bellenden Ker in northern Qld.


Specimens previously treated as S. hamulosum but now as S. eminens can be distinguished by

Both species can be distinguished from S. dimorphispinum, the other species in the S. hamulosum group of subg. Leptostemonum (Bean 2004), by the presence of a central ray in the stellate hairs; this is lacking in S. dimorphispinum .


A line drawing of S. eminens can be found in Austrobaileya 6: 755 (2004).


Derivation of epithet

From the Latin, eminens meaning “projecting" or "high”,  a reference to the altitude at which this species grows (1500-1600 metres), the highest for any Australian Solanum.
