Abstract

Plant specimens coded as Dung 051120221 at Hanoi (HN) Herbarium ofthe Institute of Ecology and Biological Resources, were identified as Microchiritabimaculata (D. Wood) A. Weber & D. J. Middleton. This is a newly recorded speciesfor the flora of Vietnam. The morphological comparison method is appliedappropriately in the study. Microchirita in Vietnam includes 8 updated species: M.aratriformis (D. Wood) A. Weber & D. J. Middleton, M. bimaculata (D. Wood) A.Weber & D. J. Middleton, M. hamosa (R. Br.) Yin Z. Wang, M. involucrata (Craib)Yin Z. Wang, M. lavandulacea (Stapf) Yin Z. Wang, M. minor Z. B. Xin, T. V. Do& F. Wen, M. purpurea D. J. Middleton & Triboun, M. rupestris (Ridl.) A. Weber& D. J. Middleton. M. bimaculata is distinguished from the remaining 7 species bythe characteristics of ”bracts absent; corolla yellow with a red-brown patch inside”.The identification key for species of the genus Microchirita currently known inVietnam was established. M. bimaculata in Vietnam has been described in detailwith accepted scientific name, synonym, morphological description, loc. class.,typus, ecology, flower and fruit season, distribution, research sampling, images.
