Abstract

A new species of Smilax, S. bolavenensis (Smilacaceae), is described from the Bolaven Plateau, southern Laos. It is similar to S. elegantissima in its elongated inflorescence with slightly zigzagged rachis longer than 20 cm, but the new species is distinguished by its terete stem and petiole (vs. 4-angled with each corner narrowly winged in S. elegantissima) and 42–54-flowered umbels (vs. 7–12). A description, photographs and preliminary conservation status are also provided for S. bolavenensis.
