B. ignita

Plant perennial, monoecious. Stem procumbent and rooting at nodes, ascending at the apex, olive to magenta, 8–20 cm long, 4–6 mm across, glabrous, internodes 0.5–5 cm long. ; A very attractive orange-flowered Begonia, claimed to be of likely Sulawesi origin by some growers, has recently entered into cultivation inside and outside of Indonesia. It is immediately distinct from all other known Sulawesi species in its symmetric or sub symmetric leaves and orange or pale tangerine to vermilion tepals. In this study, we describe this species using measurements of herbarium specimens made from living plants in cultivation. In addition to the full taxonomic account, color plates, line drawings, and a comparison to a phenetically similar species are provided to aid in identification. This species is distinct from other species in Begonia section Petermannia by a character combination including a procumbent stem ascending only at the apex, symmetric or sub symmetric leaves, the presence of a pale band or maculation running parallel to the leaf margin, and orange tepals.; Begonia ignita is one of the most distinct and most beautiful Indonesian species in cultivation. Its colorful cordiform leaves adorned with a silvery green band or maculation running inside the margin, and the showy flammate flowers immediately make it a very attractive species. It is distinct from all other Sulawesi begonias by the symmetric or sub symmetric cordiform leaves and in being the only known orange flowered Begonia on the island. The new species resembles the Sulawesi endemic Begonia mendumiae M. Hughes (sect. Petermannia) in the creeping habit, and the band or maculation of the leaves but can be easily differentiated from B. mendumiae by the characters shown in Table 1.
