Based on morphological and molecular evidence, Luisia yunnanensis (Epidendroideae, Orchidaceae), a new species from Yunnan, China, is described and illustrated. A detailed comparison between the newly discovered orchid and other members of Luisia is presented. Molecular analysis of nrITS and plastid DNA (matK, rbcL) sequence data show that L. yunnanensis is sister to L. filiformis with strong support.

A new orchid species, Cymbidium daweishanense, from Yunnan Province, China, is described based on morphological and molecular analyses and illustrated. A detailed comparison between the newly discovered orchid and other members of Cymbidium was conducted. The new plant was similar to C. erythraeum, C. subgenus Cyperorchis, but differs in having smaller flowers, a lip free from even the basal margins of column and a glabrous column with many purple blotches. The phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) sequence data support the status of C. daweishanense as a new species.

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.

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

Pilea nonggangensis Y. G. Wei, L. F. Fu & A. K. Monro, a new species from Guangxi, China is described and illustrated. The new species is morphologically most similar to P. basicordata from which it differs by being dioecious, having peltate leaf blades, membranous stipules, paired inflorescences and larger bracts. Nuclear ribosomal internal transcribed spacer (ITS) region and plastid trnL-F intron spacer (trnL-F) DNA sequence data from the new species and 20 local congeneric species are used to resolve the systematic position of the new species within Pilea. Despite vastly different morphology the molecular evidence suggests that P. nonggangensis is most closely related to P. pseudonotata. A Global Species Conservation Assessment classifies P. nonggangensis as Vulnerable (VU).

A New Species

Recent survey efforts in the Neotropics have documented a variety of new species of planthoppers associated with palms. Herein, a new species, Herpis soros sp. n., is described from palms in lowland tropical rainforest from Costa Rica. Other species in the genus (H. metcalfi, H. albida, and H. fuscovittata) are evaluated to provide an updated diagnosis of the genus Herpis. The New World Phaciocephalus is examined because two species were described in the genus Herpis with P. fimbriolata being recorded for both Herpis and Phaciocephalus. After examining holotype material for the New World Phaciocephalus, two species were determined to belong to other genera resulting in new combinations Oropuna orba comb. n. and Persis (Anapersis) pallidovenosa comb. n. The synonymy of Syntames with Herpis is reviewed, with S. fuscus moved to Oropuna as Oropuna fusca comb. n. Finally, molecular analysis of the new species based on COI and 18S show strong support for H. soros sp. n. as a distinct clade relative to all other cenchreines available.

A New Species

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

A New Species

Xanthagaricus siamensis, a new species in the family Agaricaceae, was discovered in northern Thailand and is here introduced based on its morphological features and molecular data. It is characterized by small to medium-sized basidiomata, a convex to plano-convex with depressed center pileus when mature, the presence of greyish orange to violet-brown fibrillose squamules on the pileus, lamellae that start out white, change to pinkish white when damaged, then change to dull green with age. Additionally, the annulus is fugacious, and the pileipellis is recognized as a cutis which morphologically distinguishes it from all other known Xanthagaricus. Phylogenetic analysis of the internal transcribed spacer region (ITS) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequence data indicated that the three specimens of X. siamensis form a distinct lineage within Xanthagaricus, and they formed a well-supported clade representing the genus Xanthagaricus. Detailed illustrations of macro- and micro-morphological characteristics and descriptions are provided, as well as other relevant molecular evidence.

A New Species

A new orchid species, Liparis funingensis, from Yunnan, China, is described and illustrated in this study based on morphological and molecular analyses. A detailed comparison between the newly discovered orchid and other members of Liparis was performed. This new plant is characterized by an obovate lip and is trilobed. The sidelobes are semiorbicular and fleshy, and the midlobe is short and bilobed with triangular lobes. The disc has a deeply bilobed basal callus and two longitudinal lamellae from the base extending to above the middle. There are four pollinia in two pairs, with each pair exhibiting long caudicles without a viscidium. The rostellum also has a bursa synovialis. These features distinguish this new orchid from all other known species of Liparis. A phylogenetic analysis was subsequently performed to determine the systematic position of this enigmatic species. A molecular study based on nuclear ribosomal ITS and plastid matK DNA sequence data indicates that L. funingensis is a member of L. layardii subclade.

A New Species

Chusquea gouveiensis is a new species of tropical woody bamboo from Brazil, herein described and illustrated. It is classified within C. subg. Chusquea, mainly based on its scandent habit, triangular central bud with vertical orientation, extra-or infravaginal branching, and lemma margins free at the apex. The new species is most similar to C. gracilis because they share culm leaves with undifferentiated sheaths and blades with a folded or twisted apex, and foliage leaves and spikelets of similar length. However, C. gouveiensis is distinguished from C. gracilis by having branch complements of 40‒90 usually ascending subsidiary branches (vs. 70‒195 mostly horizontally oriented subsidiary branches), synflorescences weakly paniculate to racemose (vs. paniculate), glumes I and II collectively 0.3‒0.7 mm long (vs. 0.1‒0.2 mm long), and glumes III and IV awned and abaxially pilose to pubescent at the apex (vs. mucronate and glabrous). The two species also differ in distribution: C. gouveiensis is only known from the region of Gouveia and Diamantina, in the southern portion of the Espinhaço Range in Minas Gerais state, Brazil, in forest fragments at 1,200‒1,300 m.a.s.l., whereas C. gracilis occurs in the southern Brazilian states of Paraná, Santa Catarina and Rio Grande do Sul, in mixed ombrophilous forests between 550 and 880 m.a.s.l. Based on nuclear internal transcribed spacer (ITS) and plastid DNA sequence data (ndhF and trnD-trnT), a sixth lineage within the Euchusquea clade was identified, herein named clade VI—Chusquea meyeriana clade, comprising a significant portion of the Brazilian species of Chusquea. The new species has phylogenetic affinities with the C. meyeriana informal group and is also distinct from C. gracilis in the phylogeny.
