Thorncroftia longiflora
Thorncroftia longiflora is an endangered species of Thorncroftia commonly called the longflower whistlesweet. It is endemic to South Africa′s Mpumalanga province.
When N.E. Brown named the genus in 1912, T. longiflora was its sole species, and, in time, its geographic distribution came to be understood to be the largest. However, subpopulations in KwaZulu-Natal and Eswatini were later described as separate species (T. greenii in 2009 and T. malolotjaensis in 2025, respectively), and it is now believed to be confined to the immediate environs of the old Joe′s Luck Mine, on the Sheba Reef near Barberton, where it was first collected.
