A New Species

The genus Paris Linnaeus (1753: 367) was traditionally placed in Liliaceae (Melchior, 1964), and then in Trilliaceae, which was divided into two genera based on floral merosity: Trilliun Linnaeus (1753: 340) has trimerous flowers, and Paris has variable floral merosity (Li 1984; Zomlefer 1997; Li 1998). However, Trilliaceae were recently revised using molecular phylogenetic approaches and placed in Melanthiaceae (Ji et al. 2006; APG IV 2016; Kim et al. 2016). Paris consists of about 28 species of perennial herbs mainly distributed and endemic in eastern Asia (Osaloo & Kawano 1999; Liang & Vitor 2000; Li et al. 2017), with the center of species diversity in China, where Paris is well known for its medicinal value.

A New Species

Paris Linnaeus (1573: 367) is a temperate genus of about 27 species of perennial herbs distributed in Eurasia (Li 1998, Ji et al. 2007). Most species are restricted to East Asia, chiefly to China (19 species), with the Yunnnan-Guizhou Plateau in southwest China as the centre of species diversity (Li 1998). Paris is well known in China for its medicinal value. Those species with a thick rhizome have been used as medicinal herbs for more than 2,000 years in China owing to its analgesic, haemostatic, anti-tumor, and anti-inflammatory activities (Long et al. 2003). More than 40 commercial drugs and health products have been developed in China with Paris used as raw material (Li et al. 2015).

A New Species

Paris Linnaeus (1753: 367) comprises 28 species of perennial herbs, mainly distributed in eastern Asia (Osaloo & Kawano 1999, Liang & Vitor 2000, Li et al. 2017, Ji et al. 2017, Wang et al. 2017). These species are also known as chong-lou in Chinese and are used as traditional medicines, the thick rhizome being used as analgesic, haemostatic, anticarcinogen, antineoplastic and anti-inflammatory (Wang et al. 2015, Li et al. 2015, 2017, Ji et al. 2017). This genus traditionally was placed in Liliaceae or Trilliaceae, which was divided into two genera based on floral merosity, namely Trilliun Linnaeus (1753: 340) and Paris (Li 1984; Zomlefer 1997; Li 1998). Paris was revised recently by molecular phylogenetic approaches and placed in Melanthiaceae (Ji et al. 2006, APG IV 2016, Kim et al. 2016).

Although Gastrochilus Don (1825:32) is a small genus, its generic and interspecific relationships are still not well understood (Seidenfaden1988, Tsi 1996, Pridgeon et al. 2014, Zou et al. 2015). It comprises 64 species collectively distributed from China, India and Sri Lanka through eastern Asia and southern Japan to Indonesia and the Philippines (Kumar et al. 2014, Govaerts et al. 2015, Raskoti 2016). China is the centre of species diversity for the genus, which contains 39 species, 19 of which are believed to be endemic (Tsi 1999, Chen et al. 2009, Yi et al. 2012, Kumar et al. 2014). During our field investigation in southeastern Yunnan, two unusual species of this genus were discovered. After undertaking a comprehensive literature and herbarium review, these two species were identified as G. sect. Gastrochilus Don (1825: 32), which is characterized by stout stem with large cauline leaves. One is a new record for China, and the other is the new species.

Abstract—Hymenophyllum subg. Mecodium, composed of the taxonomically notorious H. polyanthos and approximately 15 other closely related taxa, is a common element of filmy fern communities in the tropical and subtropical moist forests. In Taiwan, although only H. polyanthos and one or two closely related taxa were recognized in recent studies, considerable morphological variation has been observed among populations throughout the island. Thus, we conducted an extensive morphological investigation, as well as a molecular phylogenetic analysis, to clarify the specific diversity and phylogenetic relationships within Hymenophyllum subg. Mecodium in Taiwan. Field and herbaria surveys helped in recognizing five morphs in Taiwan, mainly differentiated by the combination of certain traits, viz., the presence or absence of stipe wings, general frond size and shape, degree of laminar crispation, sori position, and involucre shape. The different morphs had diverse ecological preferences. The phylogenetic tree, inferred from the sequences of the plastid loci rbcL and rps4-trnS, demonstrated that Hymenophyllum subg. Mecodium materials in Taiwan comprise several well-supported lineages, mostly corresponding to the classification based on morphology. Comparing with the protologues and type specimens of 34 related scientific names, the five morphs are herein recognized as five independent species. A new species, Hymenophyllum exquisitum, is described here. Also, the status of H. paniculiflorum is reconfirmed and that of H. fujisanense, H. parallelocarpum, and H. punctisorum reinstated. Only H. exquisitum and H. parallelocarpum are endemic to Taiwan among all the species studied. In addition, the names Hymenophyllum blumeanum, H. integrum, H. microsorum, H. polyanthos, H. tenellum, and H. wrightii are now excluded from the regional flora, and several related taxa from China, Taiwan, and the Philippines are treated as synonyms. This study unravels the deep phylogenetic relationships within Hymenophyllum subg. Mecodium in Taiwan and Eastern Asia.

Abstract Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2) of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov.

A New Species

The Atlantic Forest of Brazil includes one of the highest species diversity and endemism in the planet, representing a priority for biodiversity conservation. A new species of Anemopaegma from the Atlantic Forest of Brazil is here described, illustrated and compared to its closest relatives. Anemopaegma nebulosum Firetti-Leggieri & L.G. Lohmann has been traditionally treated as a morph of Anemopaegma prostratum; however, additional morphological and anatomical studies indicated that A. nebulosum differs significantly from A. prostratum and is best treated as a separate species. More specifically, A. nebulosum is characterized by elliptic and coriaceous leaflets (vs. ovate to orbicular and membranaceous in A. prostratum), smaller leaflet blades (3.6–5.5 x 2.0–3.0 cm vs. 6.7–13.0 x 4.2–8.4 cm in A. prostratum), orbicular prophylls of the axillary buds (vs. no prophylls in A. prostratum), solitary flowers (vs. multi-flowered axillary racemes in A. prostratum) and a gibbous corolla (vs. infundibuliform corollas in A. prostratum). In addition, A. nebulosum differs from A. prostratum anatomically in having thicker leaflet blades composed of two to four layers of palisade parenchyma (vs. one to three layers in A. prostratum), and seven to eight layers in the spongy parenchyma (vs. six to eight layers in A. prostratum). A key for the identification of all species of Anemopaegma from the Atlantic Forest of Brazil is presented.

A New Species

Mangroves create unique ecological environments, furnishing a habitat opportunity for many species. The majority of published information on mangrove sponges comes from the Caribbean while few data are available from Indo-Pacific mangrove sponges. In general, species diversity of sponges in mangroves is lower than adjacent subtidal habitats in both the Caribbean and Indo-Pacific. The aim of this study is to report the first data about sponge species diversity of two mangrove forests from Bangka Island (North Sulawesi, Indonesia) and to describe a new sponge species associated with the mangroves. The survey found 19 species, belonging to 11 families and 15 genera; the samples were collected on mangrove trunks, on the roots or on the surrounding bottom. The majority of the species are typical of coral reef but two of them have been previously found only in lagoons or in mangrove habitats. These new data enlarge our knowledge about Indonesian sponges diversity and suggest the urgency to consider Indonesian mangroves as an important but underestimated element in coral reef ecological dynamics.

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

A New Species

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.
