Hedyotis koana R. J. Wang, a new species of Rubiaceae from China

Abstract

Hedyotis koana R. J. Wang is described as a new species from Guangdong, Hunan, Jiangxi, Guangxi, Fujian, and Hainan provinces of China. It is most similar to H. herbacea L. and H. pinifolia Wall. ex G. Don. because they all have narrow leaves and their capsules are loculicidally dehiscent at the top, but it differs from H. herbacea by having termi- nal or upper axillary cyme and narrow leaves, and it can be distinguished from H. pinifolia by having long flowering pedicles, sparse inflorescence, and adaxially glabrous corolla.
