Gentianella means "dwarf gentian"-- today's species reaches only 10cm (4in.) tall. The centre of diversity for the genus is South America, though the two hundred plus species are distributed throughout most temperate regions of the world. Gentianella hirculus is considered endangered by the IUCN Red List, with only 12 populations of plants remaining in the wild. Threats include grazing and, paradoxically, visitors to the park where most (all?) plants reside.
