Sect. Petermannia

Type:— INDONESIA. Sulawesi, Sulawesi Selatan, Latimojong, Palopo, Rantebala (cultivated at Bali Botanic Garden from living material collected in the wild), 16 May 2008, D.C. Thomas & W.H. Ardi 08-77 (holotype E!, isotype BO!).

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

Habitat:— Primary and disturbed hill rainforest, on rocky ground, between 1000 and 1500 m elevation.

Provisional IUCN conservation assessment:— Critically Endangered (CR) B1ab(iii), B2ab(iii). This species is known from only a few collections from the periphery of the Latimojong Forest Reserve. The collection localities are in forest patches close to human habitation and surrounded by land used for agricultural purposes (e.g. coffee plantations) and other severely disturbed forest vegetation. Exploration of various hill forest localities on the southern arm of Sulawesi 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.

Additional specimens examined:— INDONESIA. Sulawesi. South Sulawesi: Todjamboe , 9 Feb. 1929, G. Kjellberg 1931 ( BO) ; Luwu District, Latimojong Mountain Range, Desa Lambanan Dusun Tibusan , 2 Nov. 1994, J.P. Mogea et al. 6596 ( BO) ; Salu River, Karangan, Rante Lemo , Enrekang, 16 June 2010, A.R. Kartonegoro 544 ( BO) .
