Impatiens hildebrandtii Baillon (1886: 595)

Type: —Ost-Imerina, Urwaldschatten, January 1881, Hildebrandt 3828 (P holotype, B, KW, JE, isotypes)

Conservation status.— Impatiens firmula has at present only been observed at Angavokely Forest Station (S18°55’37.9” E47°44’22.1’’) at 1776 m. The species may be rare and endangered, as many montane forests in the central highlands of Madagascar have been heavily logged but it is considered by the authors as Data Deficiency (DD). The locality observed in 2008 at the summit of a hill was already destroyed in 2014 due to antenna constructions.

Impatiens hildebrandtii is at least present in large populations in the Reserve Speciale Analamazotra near Andasibe- Perinet National Park. The new Impatiens otto-eleonorae is only known from the type locality at Masoala Peninsula. Both are local endemics occurring in protected areas and could be classified as Endangered (EN).
