H. Xia & . Deng (Acanthaceae) found in Lai Chau province is reported here for the first time for the flora of Vietnam. J. neolinearifolia can be distinguished from J. procumbens L. and J. diffusa Willd. by having linear leaf blade and bracts. The specimens are deposited in the Herbarium of the Institute of Ecology and Biological Resources (HN) Ha Noi, Vietnam. A detailed description, illustration, important taxonomic notes, and key to the three already known species are provided. Keywords: Acanthaceae, Justicia neolinearifolia, new record, Lai Chau, Vietnam. INTRODUCTION Justicia L. . is one of the largest genera in Acanthaceae, which comprises about 600-800 species distributed in tropical and subtropical regions [2, 6, 8]. The genus is represented by 33 species in the Flora of Vietnam [7]. During our revisionary studies on the genus Justicia in Vietnam, we found an intersting specimen housed in the herbarium of the Institute of Ecology and Biological Resources (HN). After critical morphological examination of the vouchers, type materials and relevant literature survey [1, 3, 4, 5, 6, 9], it was identified as Justicia neolinearifolia. This taxon was hitherto recorded from China, Laos and Thailand. Present work reports this as a new record for the Flora of Vietnam. A detailed description and illustration () are provided herein. MATERIALS AND METHODS Specimens of Justicia housed at the following herbaria were examined: Institute of Ecology and Biological Resources, Ha Noi (HN); Institute of .
