Mekongga is one of the highest mountains in Southeast Sulawesi. The Mekongga region was declared as protected forest in 1994, after logging had been done in this area. A floristic study of this forest was conducted from 2009 through 2011 by visiting the area twice a year, once each during the dry and wet seasons, and collecting specimens from the flowering and fruiting plants. Other species were also recorded, but most of them cannot be identified because the plants were too young or were not in flower or fruit at the time of collection.Â Specimens of 855 species in 155 families were collected, of which 5% (44 species) are endemic to Sulawesi and 11% (91 species) are introduced species from China, South America, India, or even Madagascar.Â In addition, new records for Sulawesi were collected from Mekongga for species originally recorded from Java (50 species), Malaysia (35 species), the Philippines (28 species), New Guinea (14 species), Sumatera (13 species), Borneo (11 species), Moluccas (4 species), and the Lesser Sunda Islands (3 species). Based on these data, it seems that species have mostly migrated to Mekongga from Java, then from Malaysia and the Philippines. More than 10 new species are proposed from this area, including a bamboo (Poaceae) and members of the families Orchidaceae, Gesneriaceae, Melastomataceae, Myrtaceae, and Araliaceae. Further study of the floristic account will be done, which can be used as baseline data in support of an important proposal to designate the Mekongga area as a national park.

Field exploration of the flora of the Mekongga Mountainous area of Southeast Sulawesi was conducted from 2009 to 2011. Herbarium specimens collected during this exploration and additional collections from Herbarium Bogoriense (BO) included 21 species in nine genera of the family Gesneriaceae. These comprise one species of Aeschynanthus, four species of Agalmyla, one species of Codonoboea, seven species of Cyrtandra, one species of Epithema, three species of Monophyllaea, two species of Rhynchoglossum, one species of Rhynchotechum and one species of Stauranthera. Twelve of these species are consider-ed endemic to Sulawesi while the rest are known to occur on neighbouring islands or are more widely distributed. Monophyllaea merrilliana, previously known only from the Philippine Islands and Borneo, is newly recorded for Sulawesi. A new species of Cyrtandra collected in the Mekongga area, C. widjajae, which resembles C. gorontaloensis from North Sulawesi but differs in having shorter pedicels and curved rather than straight fruits, is described.
