Identification keys, valid name, necessary synonyms, type material citation, short description, data on ecology and distribution, as well as a list of studied voucher specimens for each species are provided. Mentioned species are illustrated with original line drawings and color photographs. Two new nomenclature combinations are proposed, namely Cyrtosia faberi (Rolfe) Aver., and C. falconeri (Hook. f.) Aver. A new genus Miguelia Aver. with 2 species – M. somai (Hayata) Aver. and M. annamica (Gagnep.) Aver. is established. Description of a new species – Peristylus tenuicallus Ormerod. discovered by P. Ormerod on the base of his studies of AMES Herbarium is also presented. Key words: Orchidaceae, flora of Vietnam, keys for identification. Аннотация. Статья продолжает публикацию серийного издания иллюстрированного критического таксо- номического обзора орхидных (Orchidaceae) флоры Вьетнама. Третья часть монографии включает предисло- вие и стандартную таксономическую обработку наиболее примитивных триб (Neottieae, Vanilleae, Gastrodieae, Nervilieae), объединяемых в подсемейство Epidendroideae и насчитывающих во флоре страны 17 родов и 41 вид. Для всех признаваемых видов приводятся законное название, наиболее важные синонимы, цитирование аутентичного материала, краткое описание, данные по экологии и распространению, а также список изучен- ных образцов. Все виды иллюстрированы черно-белыми рисунками и цветными фотографиями. Для 2 так- сонов в работе предложены новые номенклатурные комбинации – Cyrtosia faberi (Rolfe) Aver. и C. falconeri (Hook. f.)
