3C1687E7FFA5867AFF03F93AFBB3FEA9.taxon	etymology	Etymology: — Dedicated to Otto and Eleonore Gunthilde Karolina Schweizer by the family of Andreas Schweitzer on the occasion of the 80 th birthday of Eleonore for the generous support of taxonomic research. Notes: — Impatiens otto-eleonorae is related to Impatiens hildebrandtii Baillon (1886: 595), which was considered as a synonym of Impatiens firmula Baker (1883: 114) by Perrier de la Bathie (1934). It differs, however, in several features (Table 1), e. g., larger habit, the larger leaves, the inflorescences with up to 6 flowers and the larger flowers. Impatiens hildebrandtii occurs in Eastern Central Madagascar in rainforests (e. g. Andasibe and Ranomafana). Impatiens otto-eleonorae is restricted to perhumid montane forests on Masoala Peninsula.	en	Fischer, Eberhard, Rahelivololona, Marie Elisette (2015): New taxa of Impatiens (Balsaminaceae) from Madagascar VI.

3C1687E7FFA0867FFF03F88EFB7DF951.taxon	materials_examined	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 (S 18 ° 55 ’ 37.9 ” E 47 ° 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).	en	Fischer, Eberhard, Rahelivololona, Marie Elisette (2015): New taxa of Impatiens (Balsaminaceae) from Madagascar VI.
