A new species of Phalaenopsis, P. pingxiangensis, from Guangxi, China, is described and illustrated. Detailed morphological comparison between the newly discovered orchid and other members of Phalaenopsis s.l. indicate that P. pingxiangensis is similar to P. marriottiana. The new species differs from the latter in its small stature, short inflorescence with two flowers, smaller and pink flower with pale yellow sepals abaxially, orbicular petals, purple-red, flabellate lip and terete column without wings. The molecular analyses of Phalaenopsis indicate that P. pingxiangensis is a distinct species nested in P. subgenus Hygrochilus. In addition, Hygrochilus tsii is transferred to Phalaenopsis.

In this study, we describe a new orchid species, Goodyera malipoensis, from Yunnan, China. We have performed morphological and molecular analyses on this new species. A detailed comparison between the newly discovered orchid and other members of Goodyera was conducted. The new plant is characterized by having a dense brownish green pubescence on the peduncle. Its ovate-lanceolate petal is unique in Goodyera genus. The hypochile is deeply concave-saccate, and inside there are two papillose rows on each side. These features distinguish the new orchid from all other known species of Goodyera. The molecular study based on nuclear ribosomal ITS sequence data and morphological differences support G. malipoensis as a distinct species.

Based on morphological and phylogenetic studies, Selaginella qingchengshanensis, a new species in S. sect. Heterostachys from Sichuan, China is described and illustrated. Morphologically, the new species is similar to S. amblyphylla, but has sterile leaves with denticulate to slightly ciliate margins, dorsal leaves with long arista (as long as leaves) perpendicular to stems and branches in living plants, and axillary leaves triangular-ovate or broadly ovate. Molecular analyses based on ITS+5.8S and rbcL data also support it as a distinct species.

A new species, Liparis mai (Malaxidinae, Epidendroideae, Orchidaceae), from Guangxi, China, is illustrated and described based on morphological and molecular analyses. This new species is similar to L. nervosa but differs by the older pseudobulb often bearing bulbil, larger revolute lateral sepals, obovate-elliptic lip and caniniform callus. Molecular analyses of nuclear (ITS) and plastid (matK) DNA support L. mai as a distinct species, which forms an independent lineage sister to L. nervosa and its allies.

AbstractMorphological comparison of populations of Chironomus (Camptochironomus) tentans (Fabricius) from Europe, Asia and North America has confirmed earlier cytogenetic evidence that two distinct species inhabit the Palearctic and the Nearctic under this name. The Palearctic species is the true C. tentans, whereas Nearctic populations constitute a new species described here under the name Chironomus (Camptochironomus) dilutus. Descriptions of the larva, pupa and adult male of both species are presented, and the taxonomic structure of the subgenus Camptochironomus is examined.

Gloeocantharellus has an amphi-Pacific distribution, with five known neotropical species. Gloeocantharellus corneri was the only species in the genus recorded from Brazil. A new species, Gloeocantharellus aculeatus, was collected in the Atlantic Forest in the states of Espírito Santo and Santa Catarina of Brazil, and is described based on morphological and molecular characteristics. It is distinguished from other species in the genus by the orange to salmon pileus with slightly fibrillose margin, squamulose to pulverulent stipe, and aculeate basidiospores. The results of molecular analyses show that G. aculeatus is a distinct species and is closely related to G. corneri and G. echinosporus.

In the present study, we describe Ophioglossum chaloneri as a new species from the Hurdulu forest area, near Ranchi (Jharkhand, India), on the basis of morphological, palynological, cytological, and molecular analyses. The new species can be distinguished from all other congeners of genus Ophioglossum in having their unusually small linear rhizome with a long stalk of trophophore, a sporophore arising from a distance from the base of the trophophore hence not always adnate or appearing inserted at the base. Triradiate, round spores show small tubercles towards the proximal pyramidal area and irregular smooth elevated exine striations on both the proximal and distal faces. The ventral face of the trophophore is unusually thin all around margin thereby showing thin whitish margin from the lower side, a situation that may be due to lack of chloroplast all around the margin at the lower face of the trophophore. This feature is not observed in any other species of the genus. Molecular study based on three chloroplast DNA sequences (cpDNA) rbcL, trnL-F, and psbA-trnH also supports O. chaloneri as a distinct species.

A new Asteraceae species, Aster huangpingensis W. P. Li & Z. Li from Guizhou, China, is described and illustrated based on morphological and molecular analyses. Detailed morphological comparisons indicated that A. huangpingensis is similar to A. dolichophyllus. However, it can be distinguished from A. dolichophyllus by its lower leaves (2.5) 3.3–5.8 (7.5) × 0.3–0.9 cm, narrowly oblanceolate or spatulate, bracts glandular, punctate, few or absent, involucres campanulate, 3.5–5.5 mm in diam., ray florets 11–22 and disk florets 16–28, middle phyllary margins with strigillose and eglandular hairs, stigmatic appendage equilaterally triangle-shaped, and different flowering period. Molecular analyses based on nuclear ITS and ETS sequence data supported A. huangpingensis as a distinct species, and its systematic position is determined in A. subgen. Aster sect. Aster. Cytological observations showed that the new species is diploid with its karyotype being 2n =2x =18 = 16 m + 2 sm. Its only population is located on riverbanks of a stream that will become a tourist hotspot and is in urgent need for conservation actions.

Bletilla guizhouensis (Coelogyninae, Epidendroideae, Orchidaceae), a new species from Guizhou, China, is described and illustrated in this study based on the morphological and molecular evidence. Based on the morphological comparison, B. guizhouensis is closely related to B. striata, but differs in having ovate-oblong floral bracts, oblong-elliptic dorsal sepal, lip broadly-obovate, lip mid-lobe subelliptic, and disk with 7 longitudinal lamellae. These features distinguish the new orchid from all other known species of Bletilla. Molecular analysis based on nuclear ribosomal ITS and plastid DNA sequence data indicate that B. guizhouensis is a new species.

A new species of Paphiopedilum (Orchidaceae) from Yunnan, China, is described and illustrated based on morphological and molecular evidence. Morphological comparisons indicate that the new species P. notatisepalum is highly similar to P. henryanum, from which it differs by its leaves with large yellow spots, shorter scape, larger flower, ovate, white sepals and petals that are pale purple-red with large purple spots and yellow-white margins. Molecular analyses of combined nuclear and plastid datasets (nrITS and matK) indicate that P. notatisepalum is sister to P. barbigerum, which has a green leaves and pale yellow-green sepals and petals. The morphological and molecular evidence support the hypothesis that P. notatisepalum is a new species.

Camellia mingii S.X.Yang is described and illustrated as a new species from southeast Yunnan Province, China. It is morphologically closest to C. pubipetala, but can be easily distinguished by its spiral arrangement of bracteoles and sepals; its bracteoles and sepals lunate, reniform or broadly ovate, glabrous inside and densely puberulent outside; its petals orbicular to short elliptic, puberulent on both sides; and its inner filaments puberulen to ca. 2/3 from base. Molecular analyses based on GBSSI sequences also support C. mingii as a distinct species of yellow camellia. It is ‘Critically Endangered’ (CR) according to the IUCN Red List Categories and Criteria.
