抄録

Twenty four species of Lasianthus are documented from Bokor National Park, Kampot Province, Cambodia. Four new species, Lasianthus bokorensis, L. giganteus, L. oblanceolatus, and L. stephanocalycinus, are described based on newly collected materials. Nine species, L. austrosinensis, L. biflorus, L. chevalieri, L. clementis, L. curtisii, L. hispidulus, L. latifolius, L. sarmentosus, and L. viridiramulis, are newly recorded from Cambodia. Lasianthus viridiramulis is proposed as a replacement name for Lasianthus brevipes Craib non Valeton.
