Sect. Petermannia

Type:— INDONESIA. Sulawesi, South Sulawesi: Latimojong, Palopo, Rantebala (cultivated at Bali Botanic Garden from living material collected in the wild), 16 May 2008, D.C. Thomas & W.H. Ardi 08-81 (holotype E!, isotype BO!).

Additional literature:— Hughes et al. (2018: 130) [photo plate].

Distribution:— Indonesia, endemic to Sulawesi, South Sulawesi: Latimojong Mountains ( Fig. 1B ).

Habitat:— Primary hill rain forest at ca. 1350 m elevation.

Provisional IUCN conservation assessment:— Critically Endangered (CR) B1ab(iii),B2ab(iii). This species is known from only a single collection at the eastern border of the Latimojong Forest Reserve. The collection is from a forest margin in close proximity to land converted for human habitation and agriculture. Exploration of various hill forest localities on the southern arm of Sulawesi including localities in the western Latimojong mountains have not resulted in any additional collections, and hence we must assume, until more extensive collection efforts reveal otherwise, that this species has a very restricted range. Because of the extremely small EOO and AOO in combination with observed disturbance and loss of forest habitat at the border of the Latimojong Forest Reserve, we assess this species as Critically Endangered.
