Etymology:

The species is named in honor of Danish botanist, Ulf Molau, who along with, B. Lojtnant, of Aarhus University, spent six months collecting in Ecuador in 1979 and collected the species twice between May 17th and May 19th. Molau started his collecting career in 1977, spending time in the field with Gunnar Harling and Mike Madison. Later he spent half a year in Ecuador in 1985 and about four months in 1987/88, (this time with his wife, Bente Eriksen Molau). Most of Molau's collecting was at higher altitudes in the Andes including Peru and Bolivia mostly in cloud forest and paramo since he concentrated on Calceolaria (completed for the Flora Neotropica in 1988) and Bartsia (revised in 1990). Molau, now a professor in Plant Ecology at the University of Gothenburg, also works for the Swedish Ministry of the Environment as a member of the Swedish Delegation to the CBD (the UN Convention on Biological Diversity and is a lead author of IPCC).
