8. Begonia mekonggensis Girm. & Wiriad. View in CoL in Girmansyah et al. (2009: 36) ( Figures 1 View FIGURE 1 & 9 View FIGURE 9 )

Sect. Petermannia

Type:— INDONESIA. Sulawesi, Southeast Sulawesi: North Kolaka Regency, Ranteangin District, Tinukari Village , Gunung Mekongga , 18 March 2006, D. Girmansyah 579 ( holotype BO!; isotypes E!, K!, L, US).

Distribution:— Indonesia; endemic to Sulawesi, so far only known from three localities (Gunung Mekongga, Mangkutana-Pendolo divide and Rantepao-Palopo divide).

Habitat:— Secondary forest, at ca. 700–800 m altitude.

Notes:— Begonia mekonggensis is one of several putatively dioecious species which are found in Sulawesi: B. guttapila D.C.Thomas & Ardi in Thomas et al. (2009: 234), B. rantemarioensis D.C.Thomas & Ardi in Thomas et al. (2011: 240), B. sanguineopilosa D.C.Thomas & Ardi in Thomas et al. (2011: 243), and B. torajana D.C.Thomas & Ardi in Thomas et al. (2011: 246). A comparison of the salient features of Begonia mekonggensis with allied species is shown in Table 2.

Provisional IUCN conservation assessment:— Endangered EN B2ab(iii). Begonia mekongensis is known from only a few localities including lowland rainforest in the Mangkutana-Pendolo devide and upland rainforest on Gunung Mekongga, which lie about 180 km apart. The collections from Mangkutana-Pendolo are from the periphery of a legally protected area, the Faruhumpena Forest Reserve. The small EOO ( 7,168 km 2) and AOO ( 28 km 2) in combination with only few collection localities warrant an Endangered (EN) status.
