Abstract

Artabotrys pachypetalussp. nov.is described from Guangdong, Guangxi, Guizhou, Hunan and Jiangxi in China. A detailed description, distribution data, along with a color plate and a line drawing are provided. In China, specimens representing this species were formerly misidentified asA. multiflorusorA. hongkongensis(=A. blumei).Artabotrys blumeitypically has a single flower per inflorescence, whereas bothArtabotrys pachypetalusandA. multiflorushave multiple flowers per inflorescence. In addition,A. pachypetalusis readily distinguished fromA. multiflorusin having thicker and shorter petals, and connivent and somewhat trigonal or terete inner petal blades.Artabotrys pachypetalusis most similar toA. punctulatusbecause both have multi-flowered inflorescences and similar petal length, butA. pachypetalusdiffers in having cream petalsin vivo, connivent inner petal blades, and a short, raised rim above the inner petal claw.Artabotrys multiflorusshould be excluded from the flora of China because none of the Chinese specimens ofArtabotryscollected so far fall within the variation ofA. multiflorus.
