The paper presents new data on the orchid diversity in Vietnam obtained in 2016-2020. It contains descriptions of one genus (Apetalanthe) and two species new to science (Apetalanthe gracilis, Nervilia appressifolia), as well as one genus (Neottianthe) and four species (Calanthe tricarinata, Collabium yunnanense, Dendrobium praecinctum, Neottianthe...

... Due to the fugacious leafless flowering, species of the genus are often overlooked in the field surveys, and not well presented in herbaria. The genus Nervilia continues to grow with the addition of at least one new species every year during the last decade (Averyanov, 2011a, b;Gale et al., 2016;Gale & Phaxaysombath, 2017;Tang et al., 2018;Hsu, 2020;Averyanov et al., 2020). The recent discoveries of new species of Nervilia genus in Indochina show that this area has certain potentials for the finding here of other novelties belonging to this genus. ...
... During our field surveys in the Da Lat Town area in southern Vietnam, we came across an unusual specimen of Nervilia, which after critical studies of the relevant literature and herbarium specimens, was identified as Nervilia kasiensis S.W.Gale & Phaxays., a taxon never reported from Vietnam. Before this report, only ten species of Nervilia genus were recorded from Vietnam (Pham Hoang, 1999;Averyanov, 2011a, b;Chen et al., 2009;Hsu, 2020;Averyanov et al., 2020). The present report brings the total number of the species of Nervilia genus in Vietnam to eleven. ...

Nervilia kasiensis is reported here as a new record for the flora of Vietnam. It is illustrated with detailed photographs made in the field. A key for the identification of all species of Nervilia genus known in Vietnam is presented.

This paper presents new data on the orchid diversity of Vietnam obtained in 2015–2021. It contains descriptions of three new species (Cleisostoma furcatum, Malleola micrantha, Schoenorchis hungii), one new variety (Chiloschista parishii var. minutiflora) and one new form (Cleisostoma furcatum forma albiflora). Additionally six species, Ascocentropsis malipoensis, Chiloschista sweelimii, Pomatocalpa undulatum, Trachoma rhopalorrhachis, Trichoglottis maculata, and Uncifera acuminata are newly recorded for Vietnam. The paper also provides an amended description of a very rare and poorly known species, Cleisostoma equestre. All studied taxa belong to subtribe Aeridinae (tribe Vandeae, subfamily Epidendroideae). The accepted plant name, main synonyms, data on type specimens, ecology, phenology and distribution, estimated IUCN Red List status, studied specimens, brief taxonomic notes, and illustrations are provided for each species listed.

Four new species of Orchidaceae from China, Heminium lijiangense, Peristylus fasciculatus, Platanthera milinensis, and Ponerorchis gongshanensis, together with a new country record, Peristylus tenuicallus, are described and illustrated based on morphological and phylogenetic analyses. Heminium lijiangense is closely related to H. elisabethae but differs from it by having the dorsal sepal ovate-orbicular and lip mid-lobe distinctly shorter than lateral lobes. Peristylus fasciculatus is close to P. tradescantifolius but is distinguished from it by having several fascicled and straight, root-like tubers (vs. one or two oblongoid tubers), old stems usually persistent, mid-lobe of lip narrowly ligulate-lanceolate and half as long as the lateral lobes (vs. midlobe deltoid, about a third as long as the lateral lobes or less), a raised callus at the base of each lateral lobe (vs. calli absent), spur gradually attenuate toward the apex (vs. spur clavate). Platanthera milinensis is similar to P. stenochila by sharing small green flowers and lip without a spur, but differs in having a creeping rhizome, a corymbose inflorescence, and a broadly ovate and slightly 3-lobed lip. Ponerorchis gongshanensis is similar to P. faberi in its small flowers, but differs in having a linear leaf c. 3 mm wide (vs. leaf 5–13 mm wide), in the lip having collar-like raised margins on the sides of the spur entrance, and a mid-lobe which is notched at the apex but not divided into two divergent lobules that are nearly as large as the lateral lobes, as in P. faberi. All the proposed species obtained high support in phylogenetic analysis as new species. The recently described genus Apetalanthe is reduced to synonymy of Ponerorchis and a new combination is made.

The present study reports newly recorded species of vascular plants for the flora of Vietnam found in the recently established Bat Xat Nature Reserve in Lao Cai province, close to the border with Yunnan province of China. Thirteen species belonging to eleven families are reported: Acanthaceae (Strobilanthes helicta), Actinidiaceae (Actinidia melliana), Amaryllidaceae (Allium wallichii), Aquifoliaceae (Ilex fragilis), Asteraceae (Melanoseris leiolepis), Begoniaceae (Begonia yuii), Lamiaceae (Callicarpa giraldii, Clerodendrum peii, Scutellaria macrosiphon), Lentibulariaceae (Utricularia spinomarginata), Primulaceae (Lysimachia septemfida), Pteridaceae (Aleuritopteris chrysophylla) and Symplocaceae (Symplocos glandulifera). Some of these species are additionally reported from the neighbouring Hoang Lien National Park. For each species, information on its habitat, phenology, distribution and studied specimens is provided along with the photographs of the reported findings.
