A New Species

Huperzia nanlingensis sp. nov. (Lycopodiaceae) is described as a new species from southern China. The distinguishing characters, description, ecology, conservation status, detailed illustrations and photographs are provided. The species resembles H. serrata in leaf shape and serrations on the margin of leaves. However, it is clearly separated as a distinct species on the basis of quantitative morphology, anatomy, and molecular evidence. Although the observed morphological differences between these two species are superficially subtle, H. nanlingensis can be distinguished from H. serrata by purple coloration at the tip and base of leaves, higher number of teeth on one side of the tropophyll, higher seasonal index and slightly crispate leaf margin.

A New Species

Dipteris shenzhenensis, a new species of ferns from Shenzhen, Guangdong, southern China, is identified and described. It closely resembles D. chinensis but possesses several unique traits, such as long rhizome scales, castaneous stipe, and abaxially pale fronds with two fan-shaped fronds connected by a broad wing. Molecular evidence showed that D. shenzhenensis is allied to D. conjugata, whereas it has morphologically significant differences (P < 0.05) on the basis of quantitative trait statistical analysis. Overall, the morphological evidence, taken together with the result of cpDNA indicated that D. shenzhenensis is a distinct species.

Molecular Characters

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

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.

A New Species

Based on field investigations, morphological and molecular systematic studies, a new species, Caltha dysosmoides (Ranunculaceae) from southwestern China is described. It differs from all other known congeneric species by the densely dentate leaf margin, the pendulous pedicels, the scarlet flowers, the compressed filaments, and the triangular connective. To better understand taxonomy of this new species, phylogenetic analyses were conducted using a combined dataset from nrITS, plastid trnL-trnF region, and atpB-rbcL spacer. The results indicate that Caltha is monophyletic and C. dysosmoides is sister to C. sinogracilis. The conservation status of the new species is categorized as CR based on IUCN criteria.

Centaurea malatyensis Ş. Kültür & M. Bona sp. nova (Asteraceae) is described as new to science from East Anatolia (B6: Malatya: Turkey). It is morphologically similar to C. leptophylla but differs mainly in its stem, basal and cauline leaf shape and size, achene, pappus and phyllary appendages. The geographical distribution of the new species and its relatives is mapped. The ecology and conservation status of the new species is also presented. Micromorphological structures of achenes of C. malatyensis and C. leptophylla are examined by SEM.

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.

Verbascum seydisehirense (Scrophulariaceae), endemic to the Konya region of Central Anatolia, is described as new species based on the plant’s morphological features. The new species is morphologically similar to Verbascum phrygium, but it differs from it for basal leaf shape, calyx size, corolla size, corolla indumentum and glands, and capsule shape and size. In this study, a detailed description, illustration, distribution map, conservation status and ecology of the new species are provided. Additionally, the study looks in detail at pollen grains and seed coat ornamentation of Verbascum seydisehirense and includes SEM micrographs.

Two specimens of an apparently new Bulbophylum species were found in the Monts de Cristal, Gabon. They have a unique leaf shape among the species of this genus in Continental Africa. The flower shares the general morphology of Bulbophyllum saltatorium, one of the most common members of Bulbophyllum in Central Africa. Eight other taxa of the Continental African Bulbophyllum possess unifoliate pseudobulbs and long hairs on the lip. Comparison with them indicates that the new collections from Gabon represent a distinctive species, not yet known in the genus. We describe it here as Bulbophyllum pauwelsianum. The distinguishing features of the species include its leaves, which are pendant, coriaceous, linear, semiterete and v-shaped in transverse section, and its sepals, which possess relatively long hairs on their margins. A table of the taxonomic treatments of the nine Continental African Bulbophyllum taxa considered here is included. A taxonomic key and a table of the diagnostic characters of these nine taxa are given to facilitate identification. The new species is restricted to lowland forests of the Monts de Cristal in Gabon. A preliminary assessment of the conservation status, using the IUCN Red List Categories and Criteria is provided.

Russula subrutilans sp. nov., a new species of Russula is described from southern China. It is unique for having buff pink to light congo-pink pileus, distant ventricose to subventricose lamellae with rare lamellulae, globose to broadly ellipsoid spores with bluntly conical warts forming a partial reticulum, and narrowly clavate to clavate cheilocystidia and pleurocysitidia with variable tips. Phylogenetic relationships among the new species and other closely related species in the genus are inferred based on the internal transcribed spacer (ITS) region.
