Abstract

Begonia fangii, a new species of sect. Coelocentrum from limestone areas in southwestern Guangxi Zhuang Autonomous Region, China, is described and illustrated. Somatic chromosome number (2n = 30) is here reported. Begonia fangii is similar to B. hemsleyana (sect. Platycentrum) in having palmately compound leaves, but it is sharply distinct in having long creeping stem (vs. erect stein with a short rhizome); leaf with (3-)4-5(-7) [vs. (6-)7-10(-12)] leaflets; styles 3 (vs. 2); and ovary I-locular with parietal placentation (vs. ovary 2-locular with axile placentation).
